Tools

A subwoofer is a pretty simple device. It’s got a cone, some copper and a big magnet. How you arrange, package, and design those parts, though, leads to hundreds of options. Choosing the right one can be a time-consuming mess of numbers and brands claiming to be the best. To combat that, we put together some tools to get you thumping asap.

Advantages of an 8″ Subwoofer
There are many advantages to the very approachable 8″ subwoofer. They represent a great first step in an audio upgrade.
First of all, 8″ subs often fit into factory systems. If your car came with a sub, it’s probably an 8-inch cone. Second of all, they offer the least expensive way to get into the world of sweet, sweet bass. You don’t need a huge amp to drive them, and you don’t need giant, expensive enclosures.
How to Choose an 8″ Sub for Your Car
First up is this quick buying guide. We’ll hit all the key things you need to know. Afterward, we will hit you with our recommendations, so you don’t have to slog through pages of garbage. At the end, after the list, is a ton of information about subwoofers. It’s there just in case you want to know about the nitty-gritty or talk shop with the bass king at your cars and coffee.
Type of Subwoofer
The first thing we need to cover is the type of sub you want to buy. It is pretty general, so don’t worry about knowing about ohms, resistance, or RMS just yet. You just need to know where the sub is going to fit into your audio system design.
There are three main types, four if you include non-aftermarket options. You can dive into the fourth and learn more about each at the bottom here if you want.
Component Subwoofers: Component Subwoofers are just speakers all by themselves. You will need a place to mount them, an amp to power them, and all the wiring to tie them in.
Enclosed Subwoofers: Enclosed subwoofers come in their own enclosure. That’s really convenient if you already have an amp and have space to work with.
Powered Subwoofers: Powered subwoofers, or ‘all-in-ones,’ come with an amp and an enclosure. A powered sub takes all the thinking out of it. Run some wires to it and boom, done.
Power Rating
Speakers have three primary measurements: the peak wattage, the RMS wattage, and the resistance.
Peak vs. RMS
Peak wattage is how fast you can run a mile. RMS wattage is how fast you can run a marathon. Advertisers like to show you the peak power because it’s a big number. It’s really not very important since running a speaker at peak will destroy it quickly. For more on the numbers, head down the page here.
Resistance
On a speaker, you’ll usually see a funny little omega symbol like this: Ω. That’s the ohms. Most car audio equipment is 2-ohm or 4-ohm, but some subwoofers can be as low as 1-ohm. Ohms affect sound clarity, with lower ohms producing lower-quality sound.
Matching Your Amp to Your Subwoofer
Amps will have an RMS rated at multiple ohms. Just make sure that you match both. If you don’t, you’ll have problems. Let’s say you hook a speaker rated to 200w RMS at 4ohms to an amp putting out 200w RMS at 2ohms. You’ll actually be feeding your speaker twice the energy it’s rated for, and it will blow up.
Hoffman’s Iron Law
The last piece of the puzzle for getting the best sub for your car is choosing the speaker’s style. Since this guide is only about 8″ subs, that makes it a lot easier. There is still a lot of variation, though, and there is no best answer. There is only the best answer for your situation and what you are willing to sacrifice. To determine that we have the awesome sounding Hoffman’s Iron Law of Speaker Building. It’s the easiest way to compare different speakers.
Hoffman’s Iron Law says that you can only choose two of the following:
Excellent Sound Quality: We go over variations in sound quality here, but it’s mostly expressed in the frequency range. The lower the optimized frequency, the better the bass will sound. Typically you want less than 50hz at the bare minimum.
High Efficiency: A sub is more efficient if it can get loud and produce good quality using less energy. In a practical sense, this is tied to cost. The more power you need, the more money you will have to shell out.
Compact Size: Most people need a sub that fits into a confined space, so you have to balance that against the other categories. Since the diameter of every 8″ speaker is 8″, like the name implies, we’ll focus on enclosure size. A bigger enclosure means more volume and clarity.
Naturally, if you want considerable volume for cheap, you will need something gigantic or something that doesn’t sound great. If you need something tiny, you will either be sacrificing sound quality or spending a ton of mullah. You can read more about it more in-depth at the bottom here.

Top 10 Best 8-Inch Subwoofers 2020
1. Best Overall 8-inch Subwoofer: Rockville SS8P Powered Under Seat 8″

View on Amazon
Why we like it: The Rockville SS8P is the best plug-and-play bass boost your sound system can get.
Editor’s Rating:

Sound Quality
The sound of the Rockville SS8P is fine: it’s not going to distort easily, but you will not be getting the lowest lows or best volume. You will also be missing some fullness because the enclosure is so shallow. That being said, it’s not for specific purposes: it’s designed to be a great all-rounder.
Efficiency
It’s inexpensive, runs off 100 watts RMS, and allows for high-level inputs. You won’t be selling a kidney to afford to run this unit. The downside is that you’re capped at 100 watts. It’s enough to fill out a factory system, but not to produce eye-watering bass.
Size
It’s not the smallest complete setup on this list, (that honor goes to the Recoil SL1708) but it’s close. You won’t have any problem finding a place to install it.
Verdict
The Rockville is an all-in-one, and it’s designed to be incredibly easy to install. That’s really cool. It means that anyone can get set up with a good hit of bass. They choose to focus on keeping it compact and efficient, which is also cool. Unfortunately, thanks to Hoffman, we know that means you won’t be getting top of the line sound quality or volume. If you want a little more volume in a system that’s still very easy to install, check out this MTX sub on our list.

Pros
Incredibly convenient, you don’t need an amp or enclosure
Inexpensive
Works with any system
Enclosure is durable and well built

Cons
Low volume
Not very much control over the sound profile

2. Best Budget 8-inch Sub: Boss Audio CXX8

View on Amazon
Why we like it: Boss is the leader of budget audio, and the CXX8 8″ sub shows us why.
Editor’s Rating:

Sound Quality
The CXX8 is optimized for 49hz, which is just about the bare minimum for a subwoofer to be acceptable. The materials are cheap too, which means it’s more prone to distortion.
Efficiency
With a 600 watt peak, you can drive this little sub using just about every amp on the market. It’s cheap and can run off of cheap amps, like the ones manufacturer Boss is famous for.
Size
This sub will fit into just about any medium-sized enclosure and thrive. It’s 4″ deep, so it’s not as shallow as others like the JBL, but it’s also not a monster that needs an entire kitchen cabinet to function.
Verdict
With the CXX8, you’re sacrificing some volume and quality for a small sub that costs pennies. If you really need the ultimate in quality from an 8″ sub, you can spend a grand easy to set up some of the powerhouses on this list. Otherwise, clean out your couch and grab one of these. It is a perfect first step into the car audio world.

Pros
Inexpensive
High wattage rating for the price
Very durable

Cons
Sound quality could be better
Wire connection points are weak

3. Best Premium 8-inch Subwoofer: Skar Audio ZVX-8

View on Amazon
Why we like it: With the Skar ZVX-8 you’ll get 15″ sub sound out of an 8″ sub.
Editor’s Rating:

Sound Quality
Ultra low-frequency response, high-quality materials, and dual voice coils make this the best sounding subwoofer on this list. You will get some distortion at high volume when you drop below 30hz, but everything is relative. For a tiny 8″ sub, that little distortion is really amazing.
Efficiency
You won’t find any efficiency here. This sub is rated to 900 watts RMS. It needs more power than every powered sub on this list hooked together, and there’s nothing cheap about that.
Size
The speaker sits at nearly 8″ deep. It’s a big unit for being so small in diameter. Still, because of the ultra high-power, you can get away with a relatively small enclosure.
Verdict
Skar is a big player in the bass world; they know how to make an audiophile smile. Unlike most 8″ subwoofers, the ZVX sacrifices your wallet instead of sound quality or volume. The only way to get louder and higher quality from a sub is to step out of the 8″ world.
You will need an amp that has enough power to drive this sub, and you will need to build a custom enclosure. If you don’t need that quality, save some money and look at this much more reasonable Skar.

Pros
Can handle massive amounts of power
Dual voice gives you tons of wiring options
Punches way above its size in volume and clarity

Cons
Expensive
Needs a serious amplifier

4. Best Sound Quality: MTX Audio RT8PT

View on Amazon
Why we like it: The MTX RT8PT is small enough to fit in the trunk without sacrificing frequency response.
Editor’s Rating:

Sound Quality
The MTX RT8PT is probably the best sounding powered sub on this list. MTX really focused on building a product that is simple to work with, and that doesn’t sacrifice frequency response.
Efficiency
It’s more expensive and uses more power than the Rockville, but it’s not bad. There’s nothing to complain about for a unit that comes with its own amp, enclosure and can be driven by any head unit.
Size
It’s squarely medium-sized. It won’t fit under your seat, and you won’t be able to hide in a factory cut out. It’s not too big, though, not like the Skar enclosed speakers on the list. There are just more compact options.
Verdict
The MTX is probably the closest you can get to a compromise on all of Hoffman’s metrics. It’s medium-sized, medium quality, and has a decent efficiency rating. Unlike the Rockville or the Recoil, it doesn’t go all-in on saving space. Unlike some of the higher power options like the Boss, it doesn’t go all-in to get the most volume out of a small speaker. It just tries to stay right in the center of everything.
If you do decide to go with the MTX, get an 8″ grate for the front. They did a great job making a beautiful carpeted enclosure. Unfortunately, they left the front of the speaker exposed to the elements. Spend the few extra dollars to protect it from loose objects bouncing around your trunk.

Pros
Very easy to install
Provides great volume for the size
Enclosure is carpeted, designed well and sturdy

Cons
Not as compact as other all in ones
The speaker is very exposed and can be damaged if not protected

5. Best Compact 8″ Component Sub: JBL Stage810

View on Amazon
Why we like it: The JBL Stage810 has a slim profile so you’ll have no problem fitting it into your build.
Editor’s Rating:

Sound Quality
With a range of 38-200hz, there’s not much to complain about. It’s not going to distort easily, and JBL is pretty well known for making great sounding audio equipment.
Efficiency
Don’t let the 800 watts on the box fool you, the JBL is only rated to 200 watts RMS. That puts it nicely in the range of most five-channel amps, and means it’s a great compromise between shelling out a ton of cash for a dedicated monoblock and the horrors of a factory sound system.
Size
It’s a bit chunkier than the Boss, but you can still get great results with a medium enclosure or factory location. We think it provides a good return on power and quality against its small size.
Verdict
The JBL is a great compromise between the low sound quality of the Boss and the crushing price of the Skar ZVX. It’s very middle of the road, afraid to take it too far in any direction. It’s not the cheapest thing, it’s not the most compact, and it’s not the best sounding, but it’s hard to go wrong for the price. If you take audio seriously but are just getting into the custom system world, this is a great sub to grow with.

Pros
Great frequency response for the size
JBL Sound Quality is top-notch
Does not need much space

Cons
More expensive than similarly built subs
Max wattage is misleading

6. Best Low Power 8-inch Sub: Skar Audio IX-8 D2

View on Amazon
Why we like it: If you don’t have a big amp but still want crystal clear bass, the Skar IX has you covered.
Editor’s Rating:

Sound Quality
Skar is at it again with the lowest lows on the list at 30hz. That’s amazing for an 8″ sub. Unfortunately, it’s rated for so little power that it will distort much faster than its bigger brother, the ZVX.
Efficiency
This amp is almost efficient enough to be used with a factory head unit. It has an RMS of 150 watts at 2-ohms, so you won’t need much to get that ultra-clear bass you want. Just don’t expect any kind of volume.
Size
The speaker itself is small. It’s short and compact, but you will want a bigger enclosure to take advantage of the frequency range and lack of volume, and you’ll have to buy or construct it yourself.
Verdict
The Skar IX-8 is all about the sound quality at low power. You will have to engineer a good enclosure to take advantage of that quality. The low power keeps everything in budget and offers a really approachable project, though. If you want to learn about cabinet building and get the most out of that project, this Skar is for you.
If you don’t want to learn about cabinet building, you can head to this area on the list and learn about Skar’s pre-built enclosures. There’s no shame in wanting to save time and let the engineers figure it out for you.

Pros
Great quality for the price
Dual voice coils mean tons of wiring options
Inexpensive

Cons
Power rating is low
Needs a custom enclosure

7. Best Weatherproof 8″ Sub: Kicker CompRT

View on Amazon
Why we like it: The Kicker CompRT can be placed anywhere. It’s shallow, well built, and weatherproof.
Editor’s Rating:

Sound Quality
The sound quality is decent. You can tell they tried their best to keep the lows low and clean while keeping the materials resistant and shallow. For your average rock and roll outing, it’s fine. If you plan on doing a thesis level analysis of Beethoven, stick with any of the Skar offerings on this list.
Efficiency
The Kicker Dual Shallow has a 600 watt peak and a very reasonable 300 watt RMS. That’s very middle of the range for 8″ subs, so if you want a compromise between using an inexpensive amp while still getting some good volume, this is a good choice.
Size
Size is where the Kicker shines. It’s very compact and shallow, and because it’s got decent power, it can still thump in a very confined space. It’s easy to install into just about anything. That includes boats, since this sub is rated for outdoor use.
Verdict
When you first look at this sub, you might run away at the sight of the price. Yes, it’s a very compact sub with some great power numbers, but so is the Boss on the list for less than a quarter of the price.
Two things set it apart and make it worth the price tag. First, it’s made of high-quality materials and can handle a higher load for longer periods than the Boss. Don’t get us wrong, Boss is an excellent company, but Kicker is a more serious player. Second, it’s weatherproof. You can install it on your Harley, or in your Jeep, or on your boat, and not give it a second thought as you blast tunes through the countryside when it’s pouring rain.

Pros
Weatherproof
Very compact design
Higher powered than other slim speakers

Cons
The waterproof design hurts sound clarity
Expensive

8. Most Features: Kicker 11HS8

View on Amazon
Why we like it: The Kicker 11HS8 is an easy to install plug and play system that has tons of options for dialing in the perfect sound.
Editor’s Rating:

Sound Quality
The Kicker Hideaway doesn’t have the lowest frequency response, and it’s likely to distort at volume. However, it shines in one area: how much control you have over the sound. Unlike other powered subwoofers that focus on being simple, the Kicker 11HS8 is crammed full of features like adjustable low pass filters and phase canceling. That way, you can tweak the sound to your heart’s content.
Efficiency
Even though it has a little more power than other compact powered subs, it’s still a little on the wimpy side, especially when you consider that it costs twice as much as the Rockville. It can feel like you are paying double the money for bass that still won’t rattle your windows.
Size
Like the name implies, you can hide this sub just about anywhere. It’s only a little bigger than the Rockville. but still a lot smaller than the MTX, so you get a good compromise between the two.
Verdict
Let’s be honest here, this is just a higher quality, marginally louder and slightly better-sounding alternative to the Rockville SS8P. It has the same qualities and drawbacks: not the best sound, okay power and great size. If you are looking for something that’s just a step up from the average compact powered sub, Kicker has you covered. It’s still incredibly easy to install and convenient.
Though, the truth is that if you are willing to put in the elbow grease, you will get a better system sourcing all the parts individually and building your own box. If you don’t see yourself placing a high value on the convenience of the 11HS8, there’s a Skar 8″ component sub on the list waiting for you.

Pros
Very easy to install
Lots of features make it easy to dial in different sounds
High volume for the size

Cons
Expensive compared to other all in ones
Bigger than other all in ones

9. Best Dual Enclosed 8-inch Subs: Skar Audio Dual 1400w

View on Amazon
Why we like it: The Skar Audio Dual is a pre-built cabinet that has so much bass it can practically break windows.
Editor’s Rating:

Sound Quality
With two high quality 30hz 8″ subs installed into an engineered enclosure, you will be getting the best sound quality that an 8″ sub can offer. The dual speaker design overcomes most of the pitfalls of a small speaker giving you mad volume without distortion.
Efficiency
It takes a ton of power to drive two subs, even if they are small. The speakers are 350 watts RMS each; even one alone takes a hefty amp to run. Together they have a 1400 watt peak. That’s getting into competition territory.
Size
When we talk about the enclosure’s size for the Skar SDR, there are two things you have to keep in mind. First, compared to a 15″ sub, it is still really tiny. The box is barely 15″ deep. Second, they are cramming two speakers into the box. That being said, this thing is two feet long, a foot and a half tall and a little over a foot deep. You are going to need a big trunk or cargo area to take advantage of a subwoofer enclosure of this size.
Verdict
It’s pretty easy to see that staying compact is not a priority with the Skar SDR-2. If you have the space, you’re getting a professionally engineered box with two high-quality subs ready to go. Just hook it up to your amp and blow the doors off.
If you are looking at the size and power requirements and thinking you could stand to scale it back slightly, the MTX we recommend might suit you better. It costs less, takes up less space, and isn’t quite as in your face. On the other hand, if the SDR-2 just doesn’t look like it’s crazy enough, Skar has you covered with the SDR-3 found over here on Amazon. No one will question your priorities when they have three tiny subs loosening their teeth.

Pros
Huge power rating
Enclosure is very well built
Comes with 2 subs for full sound

Cons
Takes up a lot of space
Needs a big amp to power it

10. The Most Compact 8-inch Powered Sub: Recoil SL1708

View on Amazon
Why we like it: The Recoil SL1708 is only ten inches in diameter and three inches tall. It still somehow cranks out 120 watts RMS.
Editor’s Rating:

Sound Quality
The 40-150hz range on this sub will give you okay lows, but you’ll notice that it really kills the traditional bass range’s upper frequency. That’s fine if you gravitate towards hip hop or other percussion-heavy music, but might leave you wanting more if you are into rock or metal.
Efficiency
The Recoil is cheap. Unfortunately, even though the box says 120 watts RMS, you won’t get the volume of other compact powered amps. It doesn’t have the heat dispersion to run at high watts for long, and the built-in amp is an older style class a/b amplifier that isn’t as efficient as the Rockville’s.
Size
If the sound isn’t amazing and it’s not very efficient, it’s got to be incredibly small, right? Yes. Yes, it is. It’s just under 10″ in diameter and only stands 3″ tall. The entire unit, including amp, wires, and enclosure, is smaller than some of the individual speakers on this list. That’s insane.
Verdict
With the Recoil, it’s all about size. It’s loud enough; you will still get bass that can compete with the rest of your sound system at reasonable volumes. The quality is good enough, you probably won’t be turning it up loud enough to hear the distortion. You can hide it anywhere and install it wherever you want. If you want to have fun watching your friends freak out because they can’t tell where the bass is coming from, here’s a powered sub for you.

Pros
Ultra-compact
Inexpensive
Uniquely designed

Cons
No much control over the sound
Low volume

Everything You Need to Know About Subwoofers
Here is the in-depth scoop on the topics from the quick guide, plus a few that weren’t.
The Four Types of Subwoofers to Buy
We said earlier that you really only need to concern yourself with the first three. That’s because the fourth could be several thousand pages of catalog space all on its own. These four categories will cover just about any style you can find in the wild.
Component Subwoofers
A speaker by itself is called a component speaker, since it’s one part of the system. It’s cheaper to buy them alone like this, especially with budget options like this Boss we recommend, but you’ll have to be more hands-on to install them. You’ll also need to do your own math to match the amp to the woofer.
The biggest advantage of buying a sub as an individual component is that you have full control over everything. Do you want to build in half a yacht’s worth of airspace? Go for it. Want to power it with a small fusion reactor? No problem, just make sure your wires are thick enough.
Enclosed Subwoofers
Subwoofers from the manufacturer in their own enclosure get you on the path towards bass town a lot faster than buying just the component. The engineers who built it already did the work to research, design, and tune the enclosure for you; all you need is an amp. Sub boxes like this two-speaker unit on our list by Skar will set you up to burst your eardrums fast.
The only issue is that enclosed subs tend to just be generic boxes that you have to fit into your car. That’s not an issue if you are willing to sacrifice all your trunk space or kick your passengers out. It can be annoying if you want to do something a bit more tasteful than having a big box rattling around in the back, though.
Powered Subwoofers
A powered sub is everything you need in one box. The amp is already attached, the box is already built, the speaker is already wired in. One of the advantages to a powered sub is that they can be ultra-compact, like this Rockville on the recommendation list. It can slide right under your seat and deliver sweet bass for no effort.
If you want any control over any of the components, though, then you are out of luck. You can’t add a bigger amp for more power, you can’t build a bigger box for more volume, and you can’t switch out the speaker for more depth. The price of convenience is steep sometimes.
Car Specific Subwoofers
This is the fourth category we told you not to worry about, and that’s because these subs are meant for a certain make and model. If your car isn’t that make or model, then they won’t fit.
Some cars have subs from the factory. If they do, then you can buy an upgrade for the factory system. Manufacturers may also make special enclosures that fit perfectly into your vehicle. Unfortunately, there are thousands of makes and models on the road. If you are looking for a specific factory sub for your car, you are better off looking at forums tailored to your car or speaking with your car dealer. If you’re not tied to a factory option, any of the subs on this list could work for you.
Watts, Ohms and Coils
When you talk about power in the audio world, you are talking about wattage. Watts themselves are a product of voltage and amperage, and they make a good unit for measuring energy. The higher the wattage, the more energy a device uses. In speaker terms, the higher the wattage, the more likely you are to lose your hearing. Easy enough.
The only problem is that manufacturers like to show you big numbers to make it seem better than it is. To get a feel for what a subwoofer can really do, you have to consider peak watts, RMS watts, resistance, and the number and size of the voice coils.
Peak Wattage
The peak wattage is the number they will shown first when measuring subwoofer power. The peak wattage is the maximum amount of power you can send to the speaker before it self-destructs. You don’t really ever want to hit the peak. The speaker won’t blow up right away, but it will definitely distort and sound like garbage. Plus, a lot of companies sort of, well, downright lie about the peak wattage.
Companies use absolutely perfect conditions in unrealistic temperatures to calculate the peak number. These lab numbers can be next to useless in the real world. Generally, cheaper subs like the Boss on the recommendation list will only tell you the peak numbers and hope you don’t look too close. That doesn’t mean they are bad. It just means you have to do a bit of digging or use this guide to give you the rundown.
RMS
RMS stands for Root Mean Square. While calculating this number is quite complex, a practical explanation is that RMS represents how much energy a speaker can put out over long periods. It’s a much more useful rating in the real world than the peak wattage.
The problem is that manufacturers will still fudge it so that the number is higher on the box. Even though a subwoofer might technically be rated to 150 watts RMS, the construction and wiring might mean it doesn’t sound as nice at that power level. That can lead to scenarios where a sub might stay louder than others despite a lower power rating. We have an excellent example in the recommendation section. The Rockville powered sub can get more volume out of 100w than the Recoil powered sub can get out of 120 watts.
Resistance
Resistance is measured in ohms which are represented by the omega (Ω) symbol. Lower resistance means more power, but higher distortion. Usually, people don’t prioritize sound clarity when it comes to bass, which is why subs usually sit at 2 ohm or even 1 ohm. People who really value sound quality will want to stick to speakers designed for it like the heavyweight Skar on the recommended section.
When it comes to comparing audio components, resistance is pretty straightforward. A speaker with 200 watts at 2 ohms will be louder than a speaker with 200 watts at 4 ohms. Sometimes manufacturers are really good at offering different resistances and configurations, like Skar, a company that’s particularly consistent with their product quality.
Sometimes manufacturers don’t even want to tell you what the resistance is. The JBL we recommend, for instance, seems to not want you to know that it’s a 4-ohm sub and not a more conventional 2-ohm sub, because that means it will be quieter than a 2 ohm. It’s not a bad sub by any means, but it illustrates that the numbers are never to be taken individually.
Voice Coils
Voice coils are the windings of copper that make up the heart of a speaker. The length, width, and size of wire all contribute to the sound quality and how much power they can handle. In general, and this is very, very simplified, a bigger voice coil can utilize more power and give you more bass. You can dive down a bottomless rabbit hole on this web page, but bigger is better for our purposes.
A component speaker with a larger coil like the Skar IX we recommend sounds better than the Boss, even though they have similar ratings and are the same diameter. The trade-off is that the Skar costs more and needs more room to install because like Hoffman’s Law points out: everything is a trade-off against something else.
Dual Coil Vs. Single Coil
A dual coil sub has more wiring and output options than a single coil. They don’t sound different, and it isn’t necessarily better to have a dual coil. You just have more room to play with wattage and resistance.
To see it better, look at the JBL on the list. It’s a single coil sub, it only has one set of posts. Take a good look at the Skar IX and you’ll see two separate sets. That means you can wire them up for 4 ohms, or wire multiple speakers in parallel.
Upgrading Your Sound System
A subwoofer by itself does wonders for a sound system, but it takes a lot more than an 8-inch sub to have a truly top-of-the line setup. Consider adding in the following products for a commercial-grade speaker system.
Car Stereo: Along with a new sub or driver, a car stereo is one of the best bang-for-your buck items when working on upgrading your sound system. Whether you’re just looking to move up from a tape deck or you want to add Bluetooth capability and a whole host of other features, a custom, inexpensive car stereo can make a big difference.
Sound Deadening Mats: While some cars need sound deadening mats more than others, annoying rattles and out-of-place engine noises take a lot of joy out of blasting music in your ride. sound-deadening mats can go along the way if you have an older car. Check out a list of our favorites here.
Speakers: Subs, drivers, woofers, speakers, and more, there are many factors that play into a speaker setup. Check out our list on some of the best general speaker setups on the market.
Sound Quality
It’s always hard to talk about sound quality because it can be really subjective. Some people love ultra-clear bass that punches through the rest of a song, while others like the warmer mid-range centric tones you might find in classic rock. It’s safe to say that you want to give good volume to low notes without distortion when it comes to subwoofers. Sound quality is a combination of things. Primarily, the materials the sub is built from, the style and shape of the parts, and its construction quality.
Materials
There’s a lot of thought that goes into what type of stuff a speaker is built from. The considerations include the price, the durability, and the sound they can produce. Like with all things, it’s all about trade-offs. More responsive materials are less durable. To be durable and responsive, you need to spend a lot. It’s sort of amazing how often the “you want 3 things but can only choose 2” rules come up, isn’t it?
You can see it live in our recommendations. The Kicker we recommend is made of super durable material that can handle just about anything, but you will pay for it. If not, the Boss is also made from durable materials, but the sound quality suffers for it.
Style and Shape
Style and shape include the voice coil design, which we covered previously, but it also includes other factors, like cone depth and cone shape. The bigger the speaker, the better it is at producing low notes. The smaller the speaker, the less energy it needs. This is an area best left up to the manufacturer, with no real winner: it’s more about priorities. Each manufacturer designs their subwoofer to run a balance between frequency response range and sensitivity.
The frequency range is more useful at a glance. Typical bass notes range from 20-200hz, so the lower the sub can go, the more bass clarity you will have. On the other side, if the range is too narrow, it will clip the upper range, and you might end up with holes in your sound system.
Build Quality
Compared to the other aspects that define a speaker, this one is simple. It costs money to build a speaker using principled engineering and attention to detail, so a cheap speaker probably won’t have those things. What that leads to is rattling, imprecise responses, and premature failure. Better built speakers sound better. Seems sort of obvious, but it is important to keep in mind.
Enclosures
The science of building an enclosure is something argued about in every corner of the audio world. If you are buying something like the Skar Dual above or a powered sub, you don’t have to worry about it. If you aren’t, then space is pretty much your biggest concern.
Enclosures range from simple metal boxes to full-on fancy pants DIY projects like the one in this video. There are two main enclosure styles: ported and sealed. Ported enclosures are more for resonance. They have vents and openings so that the pressure can travel further, and they tend to be louder. Sealed enclosures are quieter but offer a more defined sound. Which you choose is all about your personal preference.
As for the design and size of the box itself, if you are going to go the DIY route, just know that you are about to do a lot of research. There’s even consumer software just for that purpose of testing different enclosures virtually. It can help to check out pages like this one that offer an overview of just how many styles and ideas there are.
Turn It Up
Whether you are just starting out on the audiophile journey or want some extra bass punch for your commute, an 8″ sub is the perfect answer. After a deep dive on the best subs on the market, the only thing left for you to do is choose one, sit down and crank the volume. Just don’t blow out your eardrums. If you do, you won’t be able to enjoy that sweet bass anymore, and life without bass is boring. More

Whether you’re tired of guesstimating the distance to the back wall of the garage after a hard day at work, or you simply want to give your car a fighting chance against the student driver in your family, you’ll probably want to invest in a garage parking aid.
If one of these devices can prevent just one dent or scratch in your paintwork, then it will have already paid for itself. It’s a no-brainer to invest in one, particularly if your car is in and out of the garage multiple times per day or if many people in your household use the same garage space.

Factors to Consider in a Garage Parking Aid
There is a vast range of aids available out there catering to many different needs and preferences. You have a choice of getting something more portable, such as a gadget you install in your car, or a more permanent addition to your garage itself.
The aids can be categorized into three different types – visual, auditory, and tactile. Depending on your personal preferences you can pick what will work for you best, and in this article, we will try to guide you through the process of picking the best parking helping gadget for you.
Do You Need a Garage Gadget or a Car Gadget?
This is an important question to answer first – do you want to have aid in parking just in your garage or anywhere you go?
If you find yourself struggling to park in your tight garage, but do just fine everywhere else, investing in a garage gadget is the way.
On the other hand, if you simply struggle with flawless parking in general, equipping your car with something as simple as a rear-view camera to help you out would be best.
Portable or Permanent Garage Parking Aids
Portability is another important factor to consider, particularly if you are renting your home or if you like to change your cars often. Some aids require more work to install and are potentially more destructive than others.
Portable vs. Permanent Garage Gadgets
If you’re renting a house or a garage, most likely you don’t want to cause much damage or have to pay for repairs. In this case, choosing aids that can be easily removed without much damage are your best bet, such as ones using adhesives, for example, the Tkach Enterprises parking aid.
If you own your house and garage, and you’re perfectly fine with having a permanently installed parking aid, you definitely have a broader range to choose from. In these cases, you can really think about not just the type of aid, but the aesthetic that fits your space.
Portable vs. Permanent Car Gadgets
Just like with permanently changing your garage space, considering whether or not to permanently change your car is a major decision. Most of the sensor aids that are fitted to the car require drilling and pulling your car apart to some extent. If you like to change your cars often and are not ready to put all this work in every time, these sensor-based aids are not for you.
There are “semi-permanent” options available though, mainly in the form of rear-view cameras, that you will be able to keep with you even if you decide to sell your car.
What Kind of Sensory Help Do You Want?
Depending on the space in your garage and your portability preferences, next up is deciding what type of aid you want – visual, auditory, or tactile? Here it’s also good to think about your parking preferences – do you park front first or back? Some aids are more difficult to use if you back up into your garage, which is something to keep in mind.
Visual
The visual is among the most common types of. Usually in the form of  lasers or cameras, there’s an impressive range of fanciness in this tech.
Auditory
Some people might prefer the more traditional “beeping” guide. These aids require more work and drilling into your car for a permanent fit, but they will always let you know when your car is close to hitting something by beeping when backing up.
Tactile
These are extremely popular, more permanent additions to your garage. They’re usually in the form of floor blocks or mats, which act like a curb. You set it up on your garage floor where you want your wheels to bump into the curb and let you know you’ve parked far enough.
With these, it’s important to consider the distance between your front wheels and the bumper, as well as rear wheels and the back bumper. You need to be aware that if you set it up for your front wheels, it may not work for backing up into the garage!
Garage Parking Aid Installation
Closely related to the portability of the aid, the installation difficulty and time required to install play a role. Some installations can be more difficult than others and will require you to take apart a bit of your car, or drill holes into the bumper.
Others will require drilling into your garage ceiling, walls, or floor. The more basic installations rely on adhesives, which can leave some residue after you remove the device.
Now that you know what to consider when choosing a garage parking aid, let’s check out the best options available today.

Top 10 Best Garage Parking Aids 2020
1. Best Overall Garage Parking Aid: eRapta ERT01 2nd Generation Car Rear View Camera

View on Amazon
Why we like it: It’s not just a garage parking aid; it’s a great visual aid that will help with your parking anywhere you go in your car.
Editor’s Rating:

This rear-view camera is a semi-permanent option to install in your car to aid you with parking in your garage and beyond. It’s a nice tech gadget with an affordable price tag that will help you with rear parking. You can check out a whole range of cameras that can aid you with parking in this article.
Main Features
In the pack you only get the camera, leaving you to decide what type of monitor you want to use in your car, essentially avoiding waste. If you just want the whole kit, the company does offer the camera and a monitor as a pack.
The camera is waterproof and works well in low light conditions, becoming quite helpful in all kinds of weather. This little gadget will help you park in reverse not only into your garage but anywhere, as it becomes a feature of the car.
You may be wondering how this differs from a normal camera. This camera becomes a great parking aid due to its assist guidelines, helping you to judge the distances around the car. The night vision is a nice addition too, as you don’t have to necessarily put the light on in your garage to park well.
Installation
The installation is a little involved, but is simple enough if you follow the instructions. No drilling is required, but you do need to pull the cable through the car, as the camera is mounted to the rear license plate.
The 26-foot-long RCA cable running from the camera plugs into a monitor of your choice, which will ultimately display the rear-view. The camera does come with its own power supply cable that will need to be hooked up to your car.

Pros
Assisted parking anywhere you go
Great visual feedback, even at night
Very affordable

Cons
No monitor included – just the camera
Must pull the cable through the car

Editor’s Rating:

Quick Facts:
Sensory Type: Tactile
Tech Level: Very Low
Ease of Installation: Easy
This is a super simple solution to help you park just far enough in your garage, avoiding demolishing your back wall. Made out of recycled rubber, it’s essentially a long, 72-inch curb.
Main Features
This personal curb is solid, and will work for even huge cars. With a height of 4 inches, you don’t need to fear that you will go over it – it’s chunky enough that it will definitely notify you when you’ve gone far enough.
Being industrial grade and very durable, this gadget is resistant to damage from gas, oil, UV light, and moisture. Unlike some cheaper options, this curb is long enough for any car without worrying that your wheels might miss it.
Installation
The curb doesn’t use adhesives, but instead can be permanently mounted to the floor. It’s pre-drilled with 1/2 inch holes, but will require you to drill into the floor to mount it. Despite the premium price tag, the hardware is not included, so make sure you’re equipped.

Super durable
Great for even huge cars
Simple yet effective design

3. Best Budget Garage Parking Aid Tkach Enterprises Park Ranger Garage Parking Aid

View on Amazon
Why we like it: A different design to most other products, this guide is mounted on the sidewall, it’s easy to remove and modify to your preferences.
Editor’s Rating:

Quick Facts:
Sensory Type: Visual
Tech Level: Very Low
Ease of Installation: Easy
This option is very simple, very affordable, and very different from your usual parking aids. It’s mounted to the sidewall rather than the back wall, yet it is a surprisingly useful aid. If you have a little more space but still want to avoid hitting the wall or jamming your garage door into the car, this is a great guide – particularly for those who like to back in.
Main Features
This simple design consists of a bit of plastic with some red lines. Mount it where the vertical lines on the guide align from your view as a driver.
It’s definitely something different as you can have a visual to your side rather than to the front (or back) of your car. Unlike some of the other guides, this one won’t help you at all with the horizontal parking distances, so watch out for your mirrors!
Installation
Due to the design, you can mount it however you like, as long as the vertical lines align from your driver’s seat. There is a hole pre-drilled if you choose to mount it on a nail, but other options are available such as adhesives.

Pros
Sidewall mount for easy visual
Very affordable
Super easy to install
Doesn’t require any power

Cons
Not super accurate of a guide
Not a horizontal parking guide

4. Best Laser Garage Parking Aid: Maxsa Innovations Dual Laser Parking Aid with Light

View on Amazon
Why we like it: Having lasers to guide you as you park your car is just cool. Especially considering it works!
Editor’s Rating:

Quick Facts:
Sensory Type: Visual
Tech Level: Medium
Ease of Installation: Medium
Best choice for laser lovers, you will get to park your car with pinpoint accuracy. It’s a visual aid utilizing two lasers which can be used either for a single car or for two cars in the garage.
Main Features
This aid is ceiling mounted, and provides two separate lasers which you can adjust to your needs. Once you point the lasers on a predetermined spot of your car, you will be able to park in the correct position every time by looking out for that red dot. This may be quite difficult though if you normally park backward, and the positioning of the laser, in this case, will be even more important.
Once installed it is quite easy to simply readjust the lasers if you decide to change your car, saving you from messy readjustments and extra costs. The adjustment angle between the two lasers is a little tight and in some cases will not be wide enough to cover two cars.
These lasers meet the class IIIa red laser requirements, and are perfectly safe to use – just don’t look directly at the laser coming out. The motion sensor built into the system will detect movement up to 10 feet away, and only when the movement is detected the lasers will switch on.
Installation
To work, this parking aid requires AC power, and you may choose to put in some batteries as a backup in case of loss of power. A 6.5-foot-long AC power cable is supplied, and you will need to find a spot to plug it in.
The aid itself is mounted to the ceiling, meaning you’ll need to drill some holes to fix it in place. It’s a little amount of work, but it’s as easy as installing a smoke detector.

Pros
Suitable for both single and double car garages
Ceiling installation means it’s out of the way, not taking up space
Adjustable to any space and car

Cons
Requires constant AC supply
A little difficult for backward parking

5. Simplest Garage Parking Aid: STKR Concepts Adjustable Garage Parking Sensor Aid

View on Amazon
Why we like it: It’s a simple traffic light system that is adjustable to your parking needs. The colors are easily visible even backing in.
Editor’s Rating:

Quick Facts:
Sensory Type: Visual
Tech Level: Low
Ease of Installation: Easy
This parking aid is similar to Logic XYZ but even simpler. It has a single sensor to set up rather than two. Instead of displaying the distance between the sensor and the car bumper, the monitor simply shows colors – red, yellow, or green. The colors will signify how close you are to the wall and are much easier to spot than a number.
Main Features
The sensor can be set up to detect the car bumper between 6 inches and 6 feet. You calibrate it by parking at the perfect distance from the sensor and pressing a button – it’s that simple. Next time you go to park your car, the light will turn red when you reach that calibrated distance.
It’s a nice big display that is color-based, so no need to worry about specific numbers – just set it up once and look out for that color change to park at the perfect distance every time.
Installation
The installation is as simple as it gets. You’re supplied with double-sided tape and Velcro for the monitor, allowing you to stick the monitor to the wall, door, or cupboard. The sensor is attached via a wire to the monitor, and needs to be placed at the height of your bumper.
This gadget is powered by batteries, removing the necessity of hardwiring. This does mean replacing the batteries quite often however – the large bright display will drain the power quite fast. You will need to buy the 4 AA batteries separately as they’re not included.

Pros
Simple color indication of the distance
No need to hardwire
Minimal cables

Cons
The battery life can be a little short
Shortest distance of 6 inches

6. Easiest-to-Use Parking Aid: Camco AccuPark Vehicle Parking Aid

View on Amazon
Why we like it: Minimal tactile design that works, yet remains very affordable. It’s also easy to upgrade and improve if desired.
Editor’s Rating:

Quick Facts:
Sensory Type: Tactile
Tech Level: Very Low
Ease of Installation: Easy
An alternative to the stopping mat, this is even simpler to use compared to both the Guardian rubber curb and the Maxsa parking mat. Install it in a place where your tire will stop at the perfect parking distance from the wall and never worry again about hitting it. You will still need to park straight enough to contact the curb, but this can easily be modified by getting a few of these to create a ridge the width of the car.
Main Features
This little curb is made out of UV stabilized yellow resin, making it both durable and visible. It measures approximately 19 inches in length which is plenty for standard tires which can go up to 13 inches in width.
At a height of a little over 1 inch, it should be sufficient for passenger cars to feel the resistance without posing a major tripping hazard.
Installation
The aid is mounted using the provided adhesive to the garage floor, making the installation very simple. At the same time, the adhesive may skid a bit over time, requiring better tape and remounting, or hard mounting it to the floor.

Pros
Super low-key design that can be easily upgraded
Simple tactile feedback to stop you at the right distance
Suitable for any garage and car

Cons
The adhesive tape may slide a bit

7. Best Numbers-Based Parking Aid: Logic XYZ Garage Parking Assistant

View on Amazon
Why we like it: The visual display shows you the number of inches away from the sensors, making parking easy every time.
Editor’s Rating:

Quick Facts:
Sensory Type: Visual
Tech Level: Medium
Ease of Installation: Easy
If you like numbers, this is for you. This visual aid will display how far your car bumper is from the sensor, and once you know what the magic number is, you’ll be able to park in the same spot every time.
Main Features
The monitor will display the distance between the car and the sensors in inches, with a maximum distance of 99 inches. This monitor isn’t suitable for extremely tight parking spaces, where you need to park at 2 inches or less from the wall.
The product comes with a 48-inch AC power cable, meaning no fussing around with batteries. The monitor itself, although listed as white, sports more of a yellowish beige – think old 80’s computers. The upside being that most likely no one will even notice the addition; it will look as if it was always there.
Installation
Everything you need comes with this sensor, and the installation is very simple. The two sensors need to be positioned at the height of your bumper and stuck to the wall with the provided adhesives.
The monitor itself should be stuck to the wall at a height you can see from the driver’s seat – check if you can see it in the rear-view mirror as well if you’re planning to be parking up back-first. The monitor does require power, and you will need to hook it up using the AC power cable provided.

Pros
Simple sensor system displaying the distance between your car and the wall
Great for rear and front parking
Can be adjusted to the height of your car bumper

Cons
Some may find the sensor leads to be a little short
The sensor adhesive is single use

8. Most Fun Garage Parking Aid: Garage Parking Aid Ball Guide System

View on Amazon
Why we like it: More fun than the DIY tennis ball guide, plus it’s made out of soft foam so it won’t harm your windshield.
Editor’s Rating:

Quick Facts:
Sensory Type: Tactile/Visual
Tech Level: Very Low
Ease of Installation: Easy
Ridiculously simple, it’s a fun take on the DIY tennis ball aid. Stick it in the ceiling above your windshield and adjust the length of the string just so the soft foam ball bops it. Now you can park in the same spot every time when the ball contacts your car.
Main Features
The ball is made out of soft foam and bright yellow in color – you can’t miss it. It will also help you with horizontal parking as you have a nice target to go toward, meaning you will drive in, in the correct position – no need to back up and retry just so you can open your door to get out. As you get two balls in the pack, you can use it in a double-car garage.
Installation
The product comes with little screw hooks, where one needs to be screwed into the ceiling above your windshield. You can hang the ball from this hook and adjust the length of the string just so the ball touches the desired spot on your car.

Pros
Can’t get any simpler
Yellow so you can’t miss it
Adjustable to any garage or car

Cons
Not a classy looking thing
Can DIY it yourself

9. Best Permanent Garage Parking Aid: ZoneTech Parking Sensors with LED Display

View on Amazon
Why we like it: It’s a permanent addition to your car that will help with reversing anywhere you go – not just your garage.
Editor’s Rating:

Quick Facts:
Sensory Type: Auditory/Visual
Tech Level: High
Ease of Installation: On the Difficult Side
This aid will help you not only with backing up into your garage but also anywhere you need to park. However, as the sensors are installed to the back of the car, it’s not particularly helpful when driving into the garage front first. While it’s affordable, it requires a bit of time to install, so there’s a time investment even if there’s not much of a monetary one.
Main Features
You’re supplied with four sensors, an LCD display, and a box all the cables connect to. The ultrasonic sensors will change the rate of beeping as you approach closer to an obstacle. As the sensors are connected to your rear lights, the sounds will only activate when you’re in reverse.
Even though the beeping is at the core of this parking aid, it can be much too loud for some people. If you want to reduce the volume of the sound, you will need to pop open the LCD display and put some tape on the speaker.
In addition to the sound feedback, the LCD display will also visualize the distance for you, in the form of colored bars ranging from green to red.
Installation
Now for the difficult bit – installation. The four sensors need to be installed into the bumper of your car. This means you will need to drill holes, with the supplied drill bit, into your bumper for those sensors to fit into.
The wires going from the sensors need to be pulled to the front of the car and into the main hub the LCD display is also plugged into. In addition, the sensors need to be wired to the rear lights’ circuit so the sound activates only when you back up and the lights go on.
While this parking aid may be a great upgrade to your car, you really should know what you’re doing if you want to get it all installed correctly.

Pros
Helps with backing up
A permanent addition to your car
Affordable

Cons
Can be too loud
A little more advanced to install

10. Best Portable Garage Parking Aid: Maxsa Innovations Parking Mat

View on Amazon
Why we like it: A simple, portable, and affordable solution to aid your parking. Can easily equip your garage with one, wherever you need it.
Editor’s Rating:

Quick Facts:
Sensory Type: Tactile
Tech Level: Very Low
Ease of Installation: Easy
Set up this tactile parking aid for one (or both) of your front tires to rest in, and you will know you’re in the right spot every time. Due to its size, you have to be able to park well enough, as the mat can be quite easy to miss.
Main Features
You get a small range of colors to choose from, allowing for some aesthetic customization to your space. The mat is made out of hard plastic rather than rubber, making it prone to breaking.
You can position this parking mat how you like; however, it’s quite a narrow guide at 11 inches. While 11 inches may be sufficient for most passenger cars, it becomes quite a small target to run over if you have a bigger truck.
Installation
In order to install this parking guide, you can either hard-mount it to the floor, or simply use the adhesive provided. However, the adhesive strip isn’t particularly effective and can leave a nasty mess on the garage floor.

Pros
Easy to install
Simple tactile design
Low-key improvement to your space

Cons
Can break quite easily
The adhesive leaves a mess

Complete Guide to Garage Parking Aids
You may be wondering what’s the deal with parking aids, particularly if you’re new to parking in a garage. I mean is it not just a matter of “get good”? Well yes, but not exactly – you may be amazing at parking but just want that safety net, ensuring that you will park in exactly the same spot every time. Or it can be used as a way of getting good – more experience parking with an aid, and hence parking well, means you will eventually develop a sense of how to park without an aid.
How Do Garage Parking Aids Work?
The main objective of an aid is to help you park in exactly the same spot time and time again. How you want to be notified that you hit the spot is up to you. Tactile options will work without fail – set it up once and when you’re in the right position the tires will hit the bar. Some aids inform you through a visual display, either with numbers or colors.
Why Should I Invest in a Garage Parking Aid?
There are many benefits associated with using a parking aid. It’s nothing to do with pride, but with saving money in the long run. Fewer times you have dates with the wall, the better off your insurance and pocket is going to be. Plus you’ll be taking care of the garage as well, not just your car.
Garage repairs and maintenance can get expensive. If you’re using your garage as a workshop as well, ensuring you park right will protect the potentially expensive tools and equipment you have. It can also help you to start parking in the garage if you aren’t doing so already, minimizing the chances of car theft. If you’re scared you will trash your car or start moving the garage walls, an aid can help you to learn how to park in these tight spaces.
High Tech or Low Tech Garage Parking Aids?
Both are great options and it purely depends on your personal preference. Low tech doesn’t necessarily mean worse, just like high tech doesn’t mean it’s better.
High Tech Garage Parking Aids
Going for a high tech option is great if you’re naturally more of a tech-savvy person. If you love fiddling with technology, or lasers get you excited, this is for you. But high tech means a higher potential risk of it failing. Although the tech tends to be installed in the car, there are options for the garage itself as well.
You should be prepared to maintain your technological accessories, to make sure they all operate correctly. But if you’re prepared to be a bit more hands-on, you can pack your car so full of technology you end up with a homemade tesla.
Low Tech Garage Parking Aids
The benefits of going low tech include these guides simply being more reliable. They are much easier to troubleshoot and are quicker and easier to set up.
The low tech options tend to be created for the garage rather than the car, and usually take the form of a curb or a distance meter.
Is My Garage Suitable for a Parking Aid?
To determine the suitability of your garage, you should look at what you’re willing to do, what you can do, and what are potential gadget candidates.
You should also ask yourself what the main issues are in terms of parking – is it hitting the back wall? Not being able to get out of the car as you park too close to a wall? Backing in? Or simply driving in?
Some aids require permanent mounting while others use adhesives so make sure you have the space and a suitable surface to install the parking aid to. Also, be mindful of potential power requirements – some may use batteries while others need to be hardwired.
Tips to Improve Your Garage Parking
In addition to using a garage parking aid, keep these tips in mind to make parking as simple as possible.
Take Your Time When Parking
Whether you have an aid or not, you can improve the skill of parking by practicing it, just like anything else.
Reserve some time to practice parking in the garage in different ways and learn for yourself which method is best for you. Not only will it improve your parking in that specific garage but will develop your parking skills in general as you familiarize yourself with different techniques and approaches and how your car behaves.
Light Up Your Garage
Poor light makes parking so much more difficult as you just can’t see as well. By improving the lighting in the garage you can make it a lot easier on yourself to not only see the garage contents but the parking aid itself.
Take Care of Your Surroundings
Do some tidying and organization. Remove the clutter and make sure everything has its space – take some lessons from Marie Kondo and make your space spark joy – just not too much so the sparks don’t set the car on fire. Not only will the garage look better and feel better, but most importantly it will provide you with those precious extra inches of space, and save your stuff from being run over.
Final Thoughts
We’re living in a golden age of affordable technology. So why live with the stress of reversing a modern SUV into a garage designed for a VW Beetle without any help? Instead, you could just install one of these little beauties and kiss all your parking worries goodbye. More

If you are like most people, your vehicle’s air conditioning system is not something you put much thought into until it stops working properly. It can be miserable to sit in your car on a hot summer’s day when the AC barely feels cool at all. Even with your windows down, the temperature in your car can become unbearable.
Fortunately, the most common reason that an air conditioner is not cold is that the refrigerant used has either gone bad or leaked out over time. Recharging your vehicle’s air conditioner is a relatively simple job, and it is very affordable when you are able to do it on your own.
AC recharge kits make this task so easy that anyone can do it in their own garage or driveway. It just requires you to hook the kit up to the proper valves in your car, and when needed, add a can or two of new refrigerant. Even when doing this for the very first time, it will take less than an hour to complete.
When done, your air conditioner will be operating properly once again. Of course, it is important to purchase the proper AC recharge kit to get the job done right. Keep reading to see our picks for the best AC recharge kids for your vehicle in 20202.

Before Choosing an AC Recharge Kit
When shopping for an AC recharge kit, you will quickly find that there are many different types available, and the prices can range from under $20 up to hundreds of dollars. There are a number of different things that you need to be aware of in order to ensure you get the right kit for your specific needs.
Type of Refrigerant
The first thing you need to know when getting ready to recharge your vehicle’s AC system is what type of refrigerant it uses. The refrigerant is the chemical that actually causes the air to cool, which results in the cold air that you enjoy. If you choose the wrong type of refrigerant, it could damage the air conditioning system in your vehicle.
When shopping for the refrigerant, start off by making sure that it is specifically for a vehicle. While there is some overlap in the chemicals used in both residential AC systems and AC systems in vehicles, the containers that are used are not compatible. If you accidentally order refrigerant that is designed for a central air unit, or a window air conditioner, it will not fit onto the auto AC recharge kit.
Once you are certain that you are looking at refrigerant for automobiles, you will need to select the specific refrigerant that your vehicle uses. The following are the three types that you may see, and which types of cars they are typically used in. Do not, however, use this alone to choose the refrigerant you need. It is always best to look in the owner’s manual of your vehicle to make sure you are choosing the right option.
R12 – This is the least common option and will only be used for vehicles manufactured prior to 1994.
R123A – This is the refrigerant that replaced R12 and is by far the most commonly used option for vehicles on the road today.
R1234YF – This is the newest option and will be what is used for all new vehicles by 2021. Some vehicles made in 2018 or more recently already use this refrigerant.
You can learn more about each of these types of refrigerants in the full buyer’s guide found below.
Type of AC Recharge Kits
When it comes to the AC recharge kit itself, there are several different options to choose from. Which one you need will depend on a number of factors including how often you plan on using it, whether you have vehicles with different types of refrigerant, and even the positioning of the AC system in your vehicle.
Testing, Maintenance, and Recharging Kits
Full AC testing, maintenance, and recharge kits are going to be significantly more expensive than the other options, but they may be worth the investment. These kits include not only the hoses and gauge needed to add refrigerant to your AC system, but also tools to check for leaks, run pressure checks, and remove old refrigerant. Another advantage of this type of kit is that they will typically include adapters for all three types of refrigerant used in vehicles today. This will make the kit useful for any vehicle you need to service today, and long into the future.
Recharge Only Kits
Recharge only kits will usually include only a hose with a pressure gauge built in. On one end of the hose will be the coupler that attaches to the AC recharge port in your vehicle. On the other end of the hose is the coupler that attaches to the can of refrigerant. In most recharge only kits there is no adapter for different types of refrigerant, so make sure to choose one that works for the type that your vehicle requires. These kits can be used many times as long as it is stored safely. All you will need for each use is a new can of refrigerant.
Single-Use Kits
Single-use kits are by far the easiest option and are ideal for someone who does not plan on doing this type of work very often. The kit will include everything you need to recharge your vehicle once, and then you throw everything away, so you do not need to store it in your garage. These kits usually include a can of refrigerant, a pressure gauge, and a hose that connects to your vehicle’s AC system. T
he pressure gauge is usually going to be found right near the can of refrigerant and have a trigger built in to allow the refrigerant to flow into your vehicle. To use this type of kit, you simply attach the coupler to your car and pull the trigger to add the refrigerant until the pressure gauge indicates that it is full.
Choosing the Right AC Recharge Kit
Recharging your vehicle’s AC system is a simple repair job that just about anyone can do. No matter how mechanically inclined you may be, the right kit will allow you to safely add refrigerant to the AC system so you can enjoy ice-cold air the next time you drive. We have looked at dozens of different AC recharge kits and hand-selected the best options on the market. In this list, you will find full maintenance kits as well as options that are only used to complete a recharge. Read through each of the ten options listed below and select the one that is right for you.

Why we like it: It comes with everything you need to recharge and maintain your vehicle’s AC system.
Editor’s Rating:

This kit includes just about everything you could ever need for testing, servicing, and filling your vehicle’s AC system. It is an ideal choice for the ‘at home mechanic’ who is often asked to look at the cars of friends or family who may be having problems. It is even rugged enough to be used regularly, so if you own your own auto-shop or just do a lot of work on cars, this is an excellent option.
In this kit you will find the air vacuum pump that will allow you to test pressure, remove old Freon, and perform other key tasks. The pump is made with durable materials, including brass fittings, to ensure a tight fit without leaks or other problems. There are separate HVAC gauge readings for hi and low pressure, which will make it far easier to read (especially for a novice). The three hoses each have a different color, which makes it easy to avoid making mistakes on which hose is going to which part of your AC system.
While this is one of the more costly kits on the market, it will serve you well for many years, so it is a great option if you plan on having to perform this type of work more than once or twice. Once you get used to using this kit, you will absolutely love it. Unfortunately, if this is your first time working on an AC system, the instructions included with the kit are not as clear as they should be. Also, take note that this kit does not come with the actual coolant, or a tap valve for the coolant, so you have to buy those separately.

Pros
Includes tools you need to fully maintain your AC system
High-quality materials ensure it lasts a long time
Convenient carrying case included

Cons
Does not include a tap valve for common Freon refills
May be overkill for those who just want to recharge one vehicle

2. Easiest to Use: ACPRO Refrigerant

View on Amazon
Why we like it: The simplicity of this kit makes it the perfect option for anyone who is looking to recharge the air conditioning on just one vehicle.
Editor’s Rating:

If you are looking for something that is easy to use and does not have any extra tools or equipment, this is a great option. While you will not be able to diagnose problems, remove the old coolant, or check for leaks, you will be able to quickly recharge your system. This makes it perfect for those who know that all they need is a quick recharge to get their AC blowing cold again.
The refrigerant included in this kit does contain a basic leak stopping component, so if your AC unit has a small leak, this should solve that issue.
This kit comes with the refrigerant you need, the hose to connect to your vehicle’s recharge valve, and a built-in gauge to measure pressure. All you must do is connect the hose to your vehicle’s port (see your vehicle owner’s manual to locate the port) and squeeze the trigger. Watch the pressure gauge until it reaches the level recommended for your vehicle (again, refer to your owner’s manual for pressure levels). Once you have reached the desired level, disconnect the hose and turn your air conditioning on to test it out.
The refrigerant that is included with this kit works very well and will have your air conditioning blowing very cold air right away. The one issue we found with this kit is that the gauge is not perfectly accurate. It is certainly good enough to get the pressure where you need it, but it can be off by several PSI. With this in mind, it is best to just fill your vehicle to the lower end of the recommended pressure levels.
Once you see the recommended level has been reached, try your AC. If it still is not as cold as you would like it, go back and add a little more of the refrigerant until you get the cold air you need. Of course, if you have reached the high end of the pressure recommendations and it still is not cold, do not add more refrigerant. There may be other issues that need to be diagnosed by a mechanic.

Pros
Comes with everything you need to recharge your AC
Very easy to use
Refrigerant is effective and will give you the cold air you need

Cons
Gauge is not as accurate as it should be

3. Best for R-1234YF Refrigerant: InterDynamics Certified AC Pro

View on Amazon
Why we like it: The one hose design with trigger dispensing makes this kit easy to use even for automotive novices.
Editor’s Rating:

This is one of the simplest designs for recharging your AC system. It comes with just one hose that connects to a gauge, which is where you screw in your can of refrigerant (sold separately). The end of the hose has a valve that will easily hook up to the AC recharge port on your vehicle.
Once attached, you simply pull the trigger until the pressure gauge shows the level where you want it. The gauge is even color-coded to help indicate when the system needs more refrigerant as well as when it is full, when it has become overfull, and when it is at dangerous pressure levels.
This kit only works with R1234YF refrigerants, so make sure that is what you need. This is the latest type of refrigerant standard for use in vehicles. Most late-model vehicles will be able to use this option, so if you drive a newer car, this is likely what you will need. If your vehicle is older, however, this kit will not work for you, so consider another option. You can check out the ACPRO Refrigerant Kit, for a similar option that works with R134 refrigerant, which works in most vehicles.
As long as your vehicle can use the R-1234YF type of refrigerant, this kit will work for you. It really could not be easier to use. The can of refrigerant will screw directly into the gauge and automatically seals in tightly to avoid wasting any coolant. The valve on the end of the hose has an opening that makes it easy to fit around the recharge port no matter where it is located. The hose is 24’’ long, which should ensure you do not have to stretch out to get it attached.

Pros
Design is simple to understand and use
Valve attaches easily to AC recharge port
Easy to read gauge helps to avoid over or under filling

Cons
Only works for R-1234YF type refrigerant

4. Best Budget Pick: Orion Motor Tech AC Kit

View on Amazon
Why we like it: This is a very affordable kit that includes everything you need to test, detect leaks, recover refrigerant, and recharge your vehicle’s AC system.
Editor’s Rating:

If you want to be able to maintain and service the AC unit in all your vehicles, it is important to buy a kit that includes all the hoses, gauges, and other items that you could need. This AC service kit from Orion Motor Tech is a great option that has everything you need at a very affordable price. While the items that you will receive when you order this kit are not made from industrial strength materials, they are more than durable enough to last for years of occasional use.
In this kit, you will get three colored hoses that are used for recharging or testing your AC unit, two pressure gauges (one for high pressure, one for low pressure), multiple different couplers and adaptors to fit almost any vehicle as well as most common types of refrigerant, and a can tap to pierce whatever bottle of refrigerant you choose. They also include a user manual that provides general instructions for how to use all the equipment included.
There is a lot to like about this kit, including the fact that it really makes testing and recharging your AC system very easy. The biggest thing to remember when buying, however, is that this kit does not include any refrigerant. You need to look up which type you need and order a can of that to do the actual recharging.

Pros
Very affordable AC maintenance kit
Includes everything you need to maintain and recharge your AC system
Included instruction manual makes it easy to use

Cons
Refrigerant is not included
Not as durable as some higher end models

5. Best for Leaks: Certified AC Pro AC Sealant and Recharge Kit

View on Amazon
Why we like it: This kit will seal small leaks in your AC system so you can keep it functioning properly.
Editor’s Rating:

If your vehicle’s AC system has a small leak, you will want to pick up this repair kit. It works just like an AC recharge, but instead of using refrigerant alone, it is specially formulated to seal leaks as well. The formula is able to seal leaks both in rubber hosing and in metal areas such as the condenser, evaporator, accumulator, and other locations. All you have to do is hook up the valve to your car’s AC recharge port and open it so that the sealant flows into the system.
Of course, if your AC system has a leak, you will also need to add additional refrigerant. The hose, valve, and can tap that are used for this product will also work on cans of R-134A refrigerant. This means if you purchase the refrigerant at the same time, you can simply use this kit to perform both the sealing and the recharging of your system.
There is no pressure gauge, however, so you will want to either have a separate pressure gauge on hand, or just be careful not to overfill your system. Many people will just add one can of the refrigerant to see if the seal is able to hold. If it does, they can get a kit with a gauge on it to make sure it is up to the proper pressure.
While the kit is definitely strong enough to be used to add the sealant and the refrigerant, it really is not meant to be reused multiple times. After you are done with it the first time, it is best to dispose of it and get a separate recharge kit if you ever have to add more refrigerant in the future.

Pros
Can effectively seal many types of leaks
Works both for sealing and recharging your AC system
Easy to use

Cons
Does not come with refrigerant
Only for R-134A systems

6. Best Premium Pick: Kozyvacu AUTO AC Repair Tool Kit

View on Amazon
Why we like it: The durable construction of this kit makes it an ideal option for anyone who does this type of work regularly.
Editor’s Rating:

This is another full AC maintenance, repair, and recharge kit that comes with everything you will need. This includes a powerful vacuum pump for removing existing coolant, testing the lines for leaks, and much more. The three hoses are color coded to make it easy to know which one to hook up in which spot based on the instructions for your vehicle.
These hoses are four feet long, which makes it quite easy to reach to the valves on any make or model vehicle. It even includes the can tap so you do not need to buy anything separately (other than the refrigerant itself) to recharge your system.
Everything in this kit is made with durable materials including the die-cast aluminum housing for the pump and the strong high-pressure hoses. This kit was clearly made for frequent use. Despite this, however, the price is still quite reasonable.
If you are the type of person who not only maintains your own vehicles but is often asked to help out with the cars of your friends and family, this is a great AC service kit that will help you to get the job done properly. All of the different pieces of equipment that come with this kit will fit into the included carrying case, which makes it even easier to take with you no matter where you happen to be.
The weakest part of this kit is the fittings on the ends of the hoses. While they were made with durable materials, they are difficult to connect to the AC system on vehicles. They really need to be placed on in perfect position, or they will not tighten down. Depending on the positioning of the valves on your vehicle, this can be quite a challenge to get them positioned properly.

Pros
Durable vacuum pump made with die-cast aluminum
Comes with everything you need to work on your vehicle’s AC system
One of the most affordable full AC maintenance kits

Cons
More difficult to attach to valves than it should be

7. Best Basic Kit: R134A AC Refrigerant Charge Host Kit

View on Amazon
Why we like it: Very inexpensive and gives you only what you need to recharge the AC system on your vehicle.
Editor’s Rating:

When you have the right tools, recharging your vehicle’s AC system is one of the easiest types of maintenance you can do on your car. If you want to be able to easily recharge your system and are not looking for anything fancy, this kit is a great option. It is just one hose with a pressure gauge in the center. All you have to do is hook one side up to the refrigerant valve on your vehicle, and the other to the can of R134A refrigerant. Once ready, turn the valve to start releasing the refrigerant into your vehicle. When the gauge reads full, close the valve, disconnect everything, and enjoy your cool air conditioning.
The kit costs a fraction of what the more advanced AC maintenance and troubleshooting kits cost and will also make it much easier for you to complete this job. When purchasing, make sure you select the right version. One of them is good for up to 100PSI with a 15.4-inch hose, and the other is good for 350PSI with a 19.5-inch hose. See your owner’s manual on your vehicle to determine what pressure level your system will require.
You will need to purchase the R134A refrigerant along with this kit in order to recharge your AC system. Once you have this kit, however, all you will need is the refrigerant to recharge your vehicle in the future, which will save you money. Also, make sure to note that this kit only works with R134A refrigerant. This is the type of refrigerant used on most vehicles on the road today, but certainly not all, so make sure to check your owner’s manual to see if this is the right option for you.

Pros
Very inexpensive
Simple to use
Options available for either 100 or 350 PSI

Cons
Only works with R134A refrigerant

8. Best for Home HVAC Use: NewPosition 4CFM AC Maintenance Kit

View on Amazon
Why we like it: This kit has the equipment needed to work on most types of HVAC systems including your vehicle, your home, and more.
Editor’s Rating:

At first glance, this kit looks like it is very similar to many other air conditioning system diagnostic and recharge options on the market. When you look closer, however, you will see that this kit not only includes everything you need to recharge your vehicle’s air conditioning system, but also everything you need to work on your home AC units as well. This is a great option for the true ‘do-it-yourselfer’ who wants to be able to diagnose and repair all types of problems on virtually any AC unit.
When it comes to your vehicle, this kit includes the vacuum pump needed to test the pressure on the system and remove existing refrigerant. It also has both a low pressure and a high-pressure gauge for accurate readings of your system. Of course, you can also use this kit to recharge your air conditioner with new refrigerant when needed.
This kit will work with just about all types of refrigerant, including R134A, so you can recharge not only your own vehicle, but other people’s as well. The kit does not, however, come with any actual refrigerant, so make sure you purchase that at the same time.
Everything with this unit is made with durable materials that are designed to stand up to the test of time. It is a perfect option for your at-home garage, and it should serve you well for many years. Just make sure that you clean everything properly after each use and add the included vacuum pump oil as needed to keep it working right.

Pros
Works on AC systems of both vehicles and homes
Has everything you need to diagnose problems and recharge systems
Made with durable materials

Cons
Does not come with any refrigerant
More costly than many other kits

9. Best Pressure Gauge: EZ Chill Car Air Conditioner Hose and Gauge

View on Amazon
Why we like it: The simple design makes it easy to check your AC system pressure and add refrigerant when needed.
Editor’s Rating:

This kit has a very simple design that makes it quick and easy to check your AC system’s pressure levels and add in refrigerant when needed. It is made specifically for vehicle’s that use the R-134A refrigerant, so it may not work on the latest makes and models. The vast majority of vehicles that are more than a few years old, however, use this type of refrigerant.
The kit has a one-piece design. On one end is the coupler that attaches to your vehicle’s low-pressure valve. It has a 90-degree angle on it, so it is simple to attach, even when the valve is not conveniently located. In the center is the gauge that clearly displays pressure levels and is even color-coded to let you know how your pressure levels are at just a glance. Finally, on the other end is the valve that attaches to the bottle of refrigerant. This valve is compatible with either a sealed or a self-sealing R-134A can of refrigerant for maximum convenience.
One nice feature of this design is that you do not actually need a can of refrigerant to test the pressure of your system. If you believe you may have a refrigerant leak, or you just want to know the pressure levels, you just snap on the one coupler to get a quick reading as a first troubleshooting step. On the downside, however, the total length of the hose on this kit is only about 10’’, which may make it more difficult to use than options with longer hoses. Overall, however, this is an excellent tool at a low price, which makes it a great option for many situations.

Pros
Very affordable
Allows you to check system pressure without refrigerant
Easy to read gauge

Cons
The hose is only about 10’’ long

10. Most Portable: Mofeez Pro AC Diagnostic Manifold

View on Amazon
Why we like it: This kit is easy to use and comes with a convenient storage case so you can take it with you anywhere you go.
Editor’s Rating:

If you want to test and recharge your vehicle’s AC system, this kit has everything you need and nothing you do not. It is ideally suited for casual home-mechanics. If you like to do your own basic maintenance, but are not looking to dive into complex repairs, this manifold has everything you need.
The red and blue hoses along with the red and blue gauges are there to let you check the pressure in your AC system. This is an essential first troubleshooting step to see if you may have a leak somewhere in your system. They will also allow you to measure the pressure as you add in new refrigerant so that you do not leave your vehicle over or under pressurized, which can cause damage.
While this kit does not have a vacuum pump so you cannot typically pinpoint the location of the leak, it will help you to determine if one exists. Given its very affordable price, it makes sense to use this kit to check pressure rather than paying a mechanic hundreds of dollars just to take a look.
When you are ready to recharge your AC system, simply hook up the yellow hose to your vehicle and the other end to the can of refrigerant (which is not included). Once the gauges reach the specified pressure needed for your vehicle, disconnect the hoses, and give your AC a test. For a basic AC diagnostic and recharging kit, you really cannot go wrong with this option.
The only downside to this one compared to some of the more expensive ones is that it does not come with the vacuum pump (which is not needed for basic diagnostics) and the materials used are not as durable so don’t plan on using it every day without it breaking.

Pros
Affordable option for diagnosing and recharging your AC system
Easy to use on any type of vehicle
Convenient carrying kit is great for storage when not in use

Cons
Materials used in this kit are not very durable

The Complete Guide Recharging Your Vehicle’s AC System
If you turned on your vehicle’s air conditioning only to find that it is not blowing as cold as it should, you will want to get it fixed as soon as possible. The air conditioning system in your vehicle is critical for your comfort on hot summer days. Whether you have recharged the AC system of a vehicle in the past or not, you want to make sure you get this job done properly to avoid causing further problems. This guide will help you learn everything you need to know to keep your vehicle’s AC system blowing cold.
Before you get started with this type of job, you will want to make sure you are confident in what you are doing. This guide will answer common questions and give you the information you need to safely recharge your vehicle’s air conditioning.
Types of Refrigerant
As mentioned in the mini buyer’s guide above, there are three types of refrigerant that are used in vehicles. Selecting the right one is essential. Learning more about each of these three types will help ensure you purchase the right can of refrigerant and the right recharge kit.
R12 Refrigerant
If your vehicle was made prior to 1994, it is likely that it had an AC system that used R12 refrigerant. R-12 is the shortened name for the chemical dichlorodifluoromethane, which was also sold under the popular brand name Freon-12. While effective, this type of refrigerant was found to be very harmful to the environment and is now best known for depleting the ozone layer. Due to this, the EPA banned its use in vehicles after 1994.
If you own a vehicle that was manufactured prior to 1994, however, you can still use this refrigerant legally. Many of these vehicles, however, were modified to use the newer refrigerant (R134A) over the years, so make sure you double-check to be sure what your vehicle uses. Even your owner’s manual may be incorrect in this case.
Due to the fact that so few cars on the road today still use this option, there aren’t any recharge kits on the list that are made specifically for this option. You can, however, buy the XtremepowerUS AC Recharge Kit because it includes an adaptor that will work with R-12.
R134A Refrigerant
From 1994 until today, the standard refrigerant used in virtually every vehicle is known as R134A. This is a chemical called Tetrafluoroethane. This chemical was found to be highly effective without harming the ozone layer. This refrigerant, however, is now known to cause the release of greenhouse gasses that take a very long time to breakdown in the atmosphere.
If your vehicle uses this refrigerant, you can select from just about any recharge kit on our list, including the easy to use ACPRO Refrigerant kit, which includes the refrigerant itself. While still much better than R12, the harmful impact on the environment is still a problem. This is why the EPA has stated that auto manufacturers that want to sell vehicles in the United States need to switch over to the new R1234YF refrigerant.
R1234YF Refrigerant
The latest refrigerant standard is the R1234YF option, which can be found in some late model vehicles even today. This is a chemical called Tetrafluoropropene. It is similar to the R134A option, but it breaks down in the atmosphere far more quickly, which reduces the negative impact it will have on the environment.
If you drive a newer vehicle, you will want to check to see if it uses this type of refrigerant. Also, if you have an R134A vehicle, you may want to consider converting it to use R1234YF. It is a relatively inexpensive conversion and will help to protect the environment. For vehicles that do use this option, a great recharge kit is the InterDynamics Certified AC Pro kit.
Save Money by Recharging Your Car’s AC
If you bring your vehicle into a mechanic’s garage, you should expect to spend hundreds of dollars just for trying to diagnose a problem. Even something as simple as recharging your AC system is going to be quite expensive, which is why many people choose to do it on their own. Even if you do not have any experience working on cars, recharging an AC system is a relatively simple and straightforward task that anyone should be able to do without a problem.

AC Recharge Kit FAQ
How Often do You Need to Recharge Your AC System?
Unlike most types of regular vehicle maintenance, there is no exact answer to this question. Air conditioning systems do not need to be serviced after a set amount of time or a set number of miles. Some vehicles will never need to be recharged, and others will need to have it done several times over the course of ownership.
Do You Need to Recharge Your AC?
Your vehicle will not have an error light or other indicator that will let you know when it is time to recharge the AC system. The only way to know if you need to perform this type of service is when you notice that the air conditioning it not blowing as cold as it once did. Ideally you should recharge the system with new refrigerant as soon as it has become obvious that it is not blowing cold air.
Will a Recharge Fix Your AC System?
If your air conditioning system is working correctly, but still not blowing cold air, it is because it is low on refrigerant. This is generally caused by tiny leaks that occur in the system over time. If this is the case, recharging your system will fix the problem right away. If there is a large leak in the system, the new refrigerant will come out right away, in which case you will need to have the broken parts replaced before adding more refrigerant.
How Do You Actually Perform the Recharge?
This is perhaps the most important question to get answered before starting. The specific answer to this question will vary based on the type of vehicle you drive, and which AC recharge kit you purchase. The general process, however, is always going to be the same. Take a few minutes to watch this video so you can see how it is done. Once you have watched the video you will simply have to locate the same valves on your vehicle and the rest should be very straightforward.
Final Thoughts
Recharging your vehicle’s AC system is a great way to stay comfortable and safe when it is hot outside. While it can be intimidating the first time you do this type of repair yourself, it is actually quite simple and it can save you a lot of money compared to bringing it into a mechanic’s garage. Just choose the right kit and follow the included instructions and you will be sitting in a nice cool car in no time. More

Windshield sun shades are a product that too many car owners ignore. Most people don’t think it’s worth the effort of installing sun shades onto their windshield every time that they get out of the car. However, doing so could seriously prolong the life of the upholstery and equipment within the vehicle. It could also keep the inside temperature of your car within a reasonable range that’s still fairly comfortable.
This isn’t a product that you just want to grab off the shelves. It’s not as easy as buying a charger for your phone. There are several considerations before choosing the best sun shade to buy for your car or truck. Keep reading to learn more about keeping your car cool and shielding it from damaging sun. You’ll also find our list of our favorite sun shades for 2020.

How to Choose the Best Windshield Sun Shades
Most windshield sun shades look oddly similar to one another. It can be hard to differentiate between two different types of windshield sun shades and narrow down your options if you don’t know what you’re looking for. The thing that sets each windshield sun shade apart from one another is the material that it’s made of, its size and fit and its ease of use. We’ll look at these factors in more detail below.
Material
This is where most windshield sun shades will vary. Although many products may look alike, they’ll actually be made from different materials. Consider the type of material that the shades are made of, how thick the material is and how well it can reflect the sun’s powerful rays away from your car. You should also ideally look for a product that has some insulating properties as well, as this will keep the inside of your vehicle cool even when it’s steaming hot outside!
There are many materials to choose from, but the best sun shades will be made out of polyester and have a thin coating of silver on top. The silver is the reflective material that prevents the sun’s rays from getting into the car.
Some other manufacturers may use other reflective materials. Another common material is nylon. Nylon windshield sun shades tend to be a bit cheaper; however, they’re not as effective at protecting the inside of your car from UV damage. It’s also not very good at keeping your car cool.
Another thing to consider about the material is its thread count (T). A higher thread count represents a higher density and tighter weave and will do a better job at blocking UV radiation.
Size/Fit
Every make and model out there will have a slightly different windshield size and shape. Make sure that you are buying a windshield sun shade that is the right size for your car. You want something that will be able to cover your entire windshield with ease to prevent any heat or UV rays from getting inside the car. Most windshield sun shades come in sizes XXS to XXL.
Some windshield sun shades are adjustable. Most of the time, you’re going to need to measure the size of the windshield and try to find a product that can offer as close of a fit as possible. Most products will have some type of flexible wiring inside that will allow you to alter the shape of the shades, so they wrap around the windshield perfectly.
Ease of Use
Last but not least, look for something that’s easy to install. You really don’t have that much room to move inside your car, so you want a product that is easy to fold and store. Ideally, the windshield sun shade shouldn’t take more than a couple of minutes to install and disassemble. Anything longer than that and the product isn’t really that convenient at all. When the sun shade is folded up, it should be small enough to store in the trunk or in the glove box. It should not take up too much space.
Now that you know what to look for, here are our top 10 selections. Looking for maximum sun protection? Be sure to also check out our list of the best side window sun shades.

3. Best Budget Pick: EzyShade Windshield Sun Shade

View on Amazon
Why we like it: This windshield sun shade can block over 99% of the sun’s rays and also reduce the heat inside the car by over 82%.
Editor’s Rating:

Overview
Every purchase comes with a storage pouch and an extra non-slip sticky dashboard mat. This mat is super convenient. You place it on your dashboard, and you can put your cell phone, change and other small items on top without worrying about them slipping.
Material
EzyShade Windshield Sun Shades are made from polyester and can block up to 99% of the sun’s rays and reduce heat in your vehicle by over 82%. It has a Solar Heat Gain Coefficient (SHGC) of 0.18. Most other sun shades don’t even come close!
The only other sun shade that can probably do a better job is the EcoNour Windshield Sun Shade. This sun shade, however, will still keep your car nice and cool even during the sweltering summer months. The material is very lightweight, strong and durable.
Size/Fit
When it comes to size and fit, you’ll find these sun shades in three different sizes: sports, standard and max. The sports size can fit a sedan like the BMW 3 series or a Buick Reatta. The standard size can fit a Chevrolet Astro or a Cadillac ATS and the max size can fit a Ford Escape or a Benz R-Class.
These sun shades come in 2 identical rectangular shades. You can install them vertically or horizontally, as a portion of each sun shade will overlap with the other. They’ll stay put even if you don’t use the visors to hold them in place.
Ease of Use
This is one of the easiest sun shades to install. All you have to do is pop them out of their storage bag and place them onto the back of the windshield. The product is also relatively easy to fold as well. All you have to do is layer the two sun shades together, twitch them into an ‘8’ shape and fold it into a circle before storing it in its pouch.

4. Best ASE-Certified: A1 210T Windshield Sun Shade

View on Amazon
Why we like it: This sun shade comes in 7 different sizes! You’ll easily find one that perfectly fits your vehicle!
Editor’s Rating:

Overview
This windshield sun shade was designed by an ASE-Certified Master Technician, so you can rest assured that it’s high in quality. Its price point is very similar to the Magnelex Windshield Sun Shade. This sun shade blocks UV rays and heat well although not as efficiently as the Magnelex Windshield Sun Shade.
Material
This product is made from a mix of polyester and nylon. Polyester is the superior material and does an excellent job at blocking almost all of the sun’s rays and heat. If you’re looking for something that’s made completely out of polyester, you’re better off with EcoNour Windshield Sun Shade. The nylon in this product does make it a bit more flexible and bendable.
Although it’s made from a mix of different fabrics, the A1 210T Windshield Sun Shade is still a fairly efficient and durable sun shade, as the thread count is 210. It has a twin-support conjoined design that makes the sun shield even sturdier.
Size/Fit
This is where this sun shade really shines! Unlike many other competitors, like the Magnelex Windshield Sun Shade, these sun shades come in 7 different sizes. It’s really easy to find a size that will fit your windshield perfectly. It offers a perfect fit on vertically short windshields. A small will fit a BMW X2 or Z4 and a XL will fit a truck like the Ford F150.
The product is made with high ductile materials. This gives it overlapping features that allow for a perfect fit that you can easily adjust.
Ease of Use
This windshield sun shade is just as easy to install and remove as most other products. Simply pop the sun shades out of their bag and they’ll unfold. You can slide your sun shade right above the dashboard on the car’s interior.
To fold the sun shade, fold the two sides together and twist it an ‘8’ shape before collapsing both sides together. You can store this product in the storage pouch that it comes with.

Pros
210 Thread Count
Blocks sun’s rays and heat efficiently
Quick installation and convenient storage

Designed by ASE-Certified Master Technician

Cons
Made from a mix of nylon and polyester

5. Best 2-Piece: Autoamerics Windshield Sun Shade

View on Amazon
Why we like it: The innovative 2-piece design makes this sun shade extremely easy to install.
Editor’s Rating:

Overview
The Automerics Windshield Sun Shade is another popular choice thanks to its innovative 2-piece design, which is similar to the EzyShade Windshield Sun Shade.
If aesthetics is a huge component of your purchase, this sun shade isn’t going to measure up to the BDT Auto Front Windshield Sun Shade, which comes in 12 different designs.
This sun shade comes with a storage pouch and two anti-slip pads for the dashboard. You can use these pads to hold small items like your keys or change.
Last but not least, this product is designed in the USA!
Material
It’s made from high density UV reflective material that’s reinforced with high strength ductile wire. This makes this product incredibly sturdy and durable. With that said, the manufacturer never specifies the thread count of the material or the exact fabric.
The EzyShade Windshield Sun Shade has the same design but is made from 100% polyester. You can rest assured that it’s high in quality, sturdy and durable.
That said, the manufacturer claims that this sun shade can offer over 99% UV protection and sun reflection. It will keep the inside of your car cool even in the scorching summer heat, and will protect the dashboard and upholstery from fading or cracking.
Size/Fit
This windshield sun shade comes in 3 different sizes: sports, standard and max.
Each sports piece measures 23.5 by 29 inches, and will fit most compact and sports cars, like an Audi R8 or a BMW 3 series, with ease. Each piece of a standard sun shade measures 28 by 31 inches and will fit most standard cars, sedans and mid-size SUVs and trucks with ease. It’ll fit a Chevrolet Astro or a Buick Cascada. A large piece measures 32.5 by 36 inches and will fit large SUVs and trucks, like a Hyundai Entourage.
The innovative 2-piece design is quite popular amongst many car owners because it can be installed vertically or horizontally. It’s easy to get the perfect fit! You can also overlap the pieces in the middle in order to accommodate different windshield sizes.
Ease of Use
This sun shade is easy to store and install. If you take the sun shades out of their storage pouch, they’ll pop open. You can place the sun shades against the dashboard and use the rearview mirror or the sun visors to hold them in place.
To store the shades, align them together and twist them into an ‘8’ shape before collapsing both sides together to create a small circle. Slide the shades into the storage bag and you’re done!
Unlike the Shinematix 2-Piece Windshield Sun Shade, it doesn’t come with an elastic that holds the small circles in place. With that said, it is quite a bit cheaper than the Shinematix 2-Piece Windshield Sun Shade, so if you can master putting the shades back into their bag without an elastic, you’re golden!

Pros
Blocks 99% of UV rays
Comes in 3 different sizes
Can be installed vertically or horizontally thanks to its 2-piece design
Easy to install and remove
Designed in USA

6. Best Designs: BDT Auto Front Windshield Sun Shade

View on Amazon
Why we like it: If you like cute or fun designs, then BDT has exactly what you’re looking for!
Editor’s Rating:

Overview
If the design of the sun shade will be a major part of your purchasing decision, this is the best brand out there because the sun shades come in many printed designs rather than just one solid color. You’ll find some cute designs like a dog wearing sunglasses, some pretty designs like butterflies, and some patriotic designs with the American flag on it. There’s really something for everyone.
You can even flip the sun shade over and use the other side. The other side doesn’t have any prints on it and is just silver in color.
Material
It’s made with a double bubble construction, and much more durable and rigid than sun shades made from polyester or nylon, like the Autoamerics Windshield Sun Shade.
The two layers of air bubbles inside make this product more rigid, so it’ll hold its form even after many years. There’s more girth to the structure, and this makes it tougher.
The double-sided layer also does an excellent job at insulating your car and preventing any UV rays or heat from entering. In fact, this sun shade can reduce the interior car temperature by 30℉ to 50℉. That’s the difference between scorching heat and tolerable warmth.
Size/Fit
Unfortunately, this product only comes in one size, so there’s not a lot of room for adjustability there. Also, the accordion style does give you some leeway and will help make this sun shade suitable for almost all personal vehicles. You’ll need to use the rearview mirror as support.
This sun shade also has tapered edges that allow for a snugger fit. There are also deep cutouts that will fit the rearview mirror.
Ease of Use
Like with all accordion style sun shades, this sun shade is incredibly easy to fold up and store away. It is, however, a bit chunky. If you’re looking for something more compact, take a look at the X-Shade Windshield Sun Shade because it can be folded up to 1/10th of its original size. This sun shade does have a Velcro strap that you can wrap around it before you put it away.
Accordion style sun shades are, however, very easy to install. All you have to do is pop it open and place it on your dashboard. The whole set-up process will only take seconds.

Pros
Comes in 12 different designs
Accordion style for easy folding
Reduces the interior car temperature by 30℉ to 50℉
Provides 100% UV protection
Dual usage on both sides

Cons
Comes in one size and not as fitted as a 2-piece design
Can be a bit chunky when folded up

Material
Made from reflective polyester, this sun shade is fairly durable and will do a great job at reflecting the sun’s rays and heat away from your car. This will keep the inside of your car as cool as possible, so you won’t have to spend as much money on AC.
Because of the material, this sun shade only comes in one color: silver. If you’re looking for more customizability, take a look at the Motor Trend Windshield Sun Shade, which comes in 7 different colors!
Size/Fit
In terms of sizing, this sun shade comes in 3 different sizes: standard, large and extra large. A standard will fit a compact like the Mercedes-Benz GLC. A large will fit a Honda Accord and an extra large will fit a Volkswagen Touareg.
Although the different sizes will give you a good fit that’s customized to the windshield size of your car, the fit isn’t as great as with a 2-piece windshield sun shade, like the Autoamerics Windshield Sun Shade. The fact that you can install the pieces vertically or horizontally allows for more adjustability.
Ease of Use
It’s easy to set this sun shade up. Simply unfold it and place it on your dashboard. When you’re done with it, fold it back up and put it in the storage pouch that it comes with. The entire process takes only seconds.

Pros
Made from reflective material
Comes in 3 different sizes
1 year warranty
100% Satisfaction Guarantee

A Complete Guide to Windshield Sun Shades

Windshield sun shades work! They’re super effective and definitely worth buying if you want to keep your car in tip-top shape. These shades were first patented in 1911 by Frank H. Ilse of Chicago, but they have only become really popular since the mid-1970s.
These products will block visible light from entering the sun and getting absorbed by the objects in the car. You need to remember that most windshields are already tinted and will block a good chunk of the UV light coming from the sun. Finding a good windshield sunshade isn’t easy. Many of the products on the market look pretty similar to one another, which is why it’s important to always read the product information to get more insight into the technologies that are incorporated into each design.
Other Factors to Consider
Although windshield sun shades are simple tools, there are many things that you need to consider when narrowing down your options. Some other factors that may come into play are listed below.
Looks
Not all windshield sun shades look the same. Many of the newer products on the market now look quite stylish. Some have interesting designs on them, and can even be used as a type of decoration. Look for a color and design that you love and is somewhat reflective of the things that you like or your personality. You’ll feel like you got a better deal if you’re able to find a product that speaks to you.
Warranty
You’d be absolutely gobsmacked at how many manufacturers offer some type of warranty on windshield sun shades. Some of these products may come with no warranty, but others may come with a lifetime replacement warranty or even a 1-year warranty like the Shinematix 2-Piece Windshield Sun Shade.
Make sure that you check the warranty that’s offered first before you buy it. A good warranty will give you peace of mind knowing that you can easily get a replacement should anything happen to the product.
Durability
Consider how long the windshield sun shade will last you and how often you’ll need to replace it. Most windshield sun shades are fairly reasonably priced and within the same price range, so you’re not really going to find a great bargain on them. The biggest difference is the quality of the sun shades and how long they’ll last. A good windshield sun shade can easily last you decades. The only time that you’ll need to replace the sun shade is when you switch to a different car.
Type
Although most sun shades look almost identical, there are different types. They include:
A custom-fit, collapsible sun shade, which will fit perfectly to your car’s windshield. These sun shades are designed with the exact same dimensions as your windshield, so it can offer full coverage. These products tend to be a bit more expensive, as they can only fit one car model.  With that said, you’ll get a much better fit. You won’t have to worry about gaps or excess material spilling out from the edges.
A universal-fit, collapsible sun shade, which is designed to be used on a variety of cars. This may not be an exact fit. There may be some gaps on the edges or some material may spill out from the sides. However, these sun shades tend to be much cheaper than custom options and will do the trick as well.
An accordion sun shade, which folds in an accordion-like manner. These sun shades are less likely to slip off the windshields and usually offer a universal fit. However, due to the accordion-like nature of these products, they tend to be a bit bulkier.
Knowing which type is best for your car can be difficult, so you’ll need to take into consideration all of the factors as well listed here as well. Any type would fit your car. Although a custom may fit perfectly, a universal-fit sun shade may still cover everything that needs to be covered.
Adhesive
Some sun shades come with adhesives that will either stick to the side of the car or to the windshield. These adhesives prevent the sun shades from slipping, especially if you’ll be away from your car for long periods of time.
How to Install Windshield Sun Shades
Accurately measure the size of your windshield before purchasing a sun shade. Get a custom fitted one or a universal one that fits as close as possible. Place the top of the sun shade between the rearview mirror and the top of your windshield and push the bottom of the sun shade against the bottom of the windshield. Push the sides in at the side as well. Keep the sun shade in place by folding down the visors. Watch the video below for a walkthrough!

PRO TIP: If the sun shades are slipping, consider taping it to the sides using Velcro tape. A 1.5-inch tape will usually do the trick just fine!
Reasons to Use Windshield Sun Shades on Your Car
Is it really worth the time and effort to place a windshield sun shade to your car every time you get out? While it is a personal choice, most experts do recommend putting in the effort for the reasons below.
#1. It’ll Cool Down Your Car During the Summer and Warm It Up During the Winter
That’s right. You should install windshield sun shades not only during the summer, but during the winter as well. Contrary to belief, it’s useful to install windshield sun shades on your car throughout the entire year.
During the summer, these shades will protect the inside of your car from becoming sweltering hot. In fact, good shades can reduce the internal temperature by up to 40 degrees! This is extremely important as the inside of your car can get a lot hotter than the outside temperature.
During the winter, these shades can also increase the temperature inside your vehicle, so you won’t freeze to death while you wait for your engine to heat up. Most windshield sun shades have heat-absorbing materials in them that won’t make the inside of your car feel toasty, but will make it bearable.
#2. It Can Block UV Rays
If you’re sitting inside your car, installing a windshield sun shade can protect you and your passengers from UV rays that can lead to skin cancer. The shades can also protect the interior from fading, so your dashboard, upholstery and console look new even as they age. UV rays can actually crack and fade your steering wheel. Last but not least, these shades can also protect electronics inside the car, like GPS devices, DVD players, phones or computer tablets that may be left inside. polyester sun shades can block up to 99% of the sun’s rays!
#3. They’re Really Affordable
For all of the things that windshield sun shades can do, they’re surprisingly affordable. You can easily buy one without breaking the bank. By installing this product, you can prevent costly repairs in the future. Replacing a cracked steering wheel can cost several hundred, if not thousands, of dollars depending on the make and model of your vehicle.
Protect the Inside of Your Car
Get a windshield sun shade to protect the inside of your car. They deflect heat, prevent UV rays from damaging the consoles and upholstery inside and are super affordable. They’re also easy to install and small enough that you can store them in a glove box or in the middle console. Best of all, you don’t need to be a rocket scientist to install them or put them away.
When looking for a windshield sun shade, take the time to research each product and consider some of our recommendations above. We’ve listed some of the best products on the market based on the materials they’re made of and other factors. More

If you have ever had to spend a night in your car, you know how absolutely brutal on your back it can be. No matter how comfortable your car is while you are cruising, the seats are just not meant to be used as a mattress. The good news is that there are many products that are intended to be used in your car as a bed.

Getting into the World of Car Air Beds
Whether you own a compact car and just need a place to stick the kids when Grandma comes over, or are a hardcore overlander with a dedicated off-road SUV for camping, there’s an airbed for you. That’s pretty sweet. However, since there is so much variety, it can be hard to know how to choose the right one.
That’s where we come in. We have a list of the top 10 car air beds complete with reviews. We also have some great extra info in our full guide below. But first, let’s get you ready with the basic info you need to know before you start shopping.
Choosing the Right Bed for You
In truth, there are not that many decisions needed to narrow down which car air bed will work best for you. That’s largely because once you choose the size, your options dwindle rapidly. After all. You would look mighty silly trying to force a gigantic mattress into a tiny car. Here is what you need to know before shopping for your car air bed.
Size
Like we said, choosing the right size is the most important thing when choosing a car air bed. There are two primary considerations concerning size: the number and size of the people going to sleep on it, and the amount of space you have in your car.
We have a guide to figuring out what your car can fit a bit further down the page, but we can’t help you decide how many people you need to sleep. We also can’t help you determine how many people you are willing to cram into a tiny space. Just take a look at the general size and make sure it fits your needs.
Materials and Comfort
Some mattresses are thin and will ruin your back. Some are so thick it will feel like sleeping on a cloud. Some are made of only PVC and squeak every time you move. There’s no real one size fits all, but we can safely say that bigger beds will be more comfortable. Both in surface area, since not being able to stretch out can be annoying, and in thickness. The thicker the air bed, the more cushion there is between you and the ground.
You’ll also want to avoid seams and crevices. Air beds can be very complicated in shape, especially when meant to conform to your car. Those shapes can create arm traps that will cause you discomfort.
Types of Car Air Beds
There are a few different types of air beds that can be used in your car, ranging from giant truck mattresses to tiny backpacking rolls. We’ll hit the main categories, but know that there are actually more.
The Back Seat Bed
The back seat air bed is fantastic for people with smaller cars who just need to spend the night once or twice in their car. It is a mattress that has inflatable parts that take up the footwells, so you get the maximum width possible.
It’s not a lot of space, but it’s better than nothing. Just be aware that if you have a sportier car, like a Mustang or BRZ, they won’t fit. Really only a backpacking mattress will fit in the back of one of those, and that may even be worse than no mattress at all.
The SUV Bed
SUV beds are meant to expand over fold-flat rear seats and take up the cargo area. It’s definitely not limited to SUVs, though. Vans, minivans, station wagons, really these beds will fit in anything with fold-flat seats. Many will even fit into standard hatchbacks like the Focus and the Prius.
If you have space, they are better for two people and more comfortable in general. They can also be pulled out and used in other places.
The Truck Bed Air Mattress
Truck bed air beds go in truck beds. They have cutouts for wheel wells so that you get the full width of the bed for sleeping. They also tend to be way thicker and more comfortable than other categories.
If you don’t own a truck, though, they are just a costly standard air mattress.
The Standard Air Mattresses
No rule says you can’t just put a regular air mattress in the back of your vehicle. In fact, it’s usually the cheapest option. You just have to make sure they will fit since they aren’t meant for anything in particular.
You’ll also have to put up with the inconvenience of it. Beds made for cars fill up the entire space; you can’t fall off an SUV air bed. They also usually have bumpers to protect your head from things like handbrakes. Typical air mattresses have none of those things. There is a genuine possibility of falling off during the night and whacking your foot on a sharp seatbelt clip. Don’t ask us how we know.
With the basics out of the way, let’s get on with the list. We tried to find a great cross-section of styles and values; you are bound to find the perfect one for your lifestyle.

Top 10 Best Car Air Beds 2020
1. Best Overall Pick: Wey & Fly Air Mattress

View on Amazon
Why we like it: The Wey & Fly Air Mattress is comfortable, easy to inflate, and fits neatly in the back of a van or SUV.
Editor’s Rating:

Fit
It’s wide enough for two people at 53in wide and long enough for the average adult at just over 6ft in length. That’s really good for a car bed. Most backseat beds are much shorter, so if you need to stretch out, an SUV mattress is what you need.
You will need a bigger vehicle though, that’s what they are designed for. It doesn’t have to be an SUV, it can be a van or crossover, but there aren’t many cars that have more than 5ft of cargo length.
Finish
The Wey & Fly Mattress is really well built. It’s got a decent plastic shell that can withstand being pierced by sharp rocks, and it’s easy to clean on top of being durable. Beige was a weird color choice, though; it shows stains fairly easily, which can be unsightly.
Comfort is the biggest benefit of this mattress. It’s chambered so that you can use it in different configurations, but it lacks the seams that other versatile SUV beds have. The only thing you might really want are extra cushions to take up footwell cavities. They are simple enough to purchase as an extra. You can grab them here.
Our Thoughts
There’s really no substitute for the length that a larger mattress like the Wey & Fly offers when it comes to sleeping in a car. Even the nicest backseat beds won’t allow the average adult to stretch out, so if you need to sleep more than once or twice in a car, you have to have that length.
Yeah, you do need a larger vehicle to use it, but chances are if you are camping or going on long road trips, you already have a crossover or SUV. If you are concerned about the fitment, there are more versatile large mattresses like the Saygogo bed we talk about later. The Wey & Fly inflates faster, is easier to work with, and more comfortable. That’s why it’s taken our top spot.

Pros
Segmented for versatility
Easy to take out of the car and use for camping, in-laws, or whatever
The seamless mattress is very comfortable

Cons
Even though the air pump is fast, it can take a while to inflate because of the chambers
White color stains easily

2. Best Budget Pick: FBSport Inflatable Mattress

View on Amazon
Why we like it: The FBSport car bed is cheap, rugged, and comfortable. What more could you want?
Editor’s Rating:

Fit
The FBSport mattress is your everyday standard backseat mattress. It has chambers that fill up the footwell space and offer the most area you can get in the back of a car. It’ll fit in the back of anything but the cars with the smallest back seats, and it’s perfect for children and pets.
It does suffer from one problem: it’s short. That’s the limitation of every backseat mattress. A car can only be so wide, after all. That means a grown adult can’t stretch out fully. If you need that, consider getting something that can fit over fold-flat seats like the Saygogo mattress instead.
Finish
At its core, the FBSport inflatable bed is a cheap air mattress. Just like the other cheap air mattress on our list, the durability isn’t as good as others. If you are really looking for a bulletproof backseat airbed, take a look at the Caloer option instead.
Aside from the short size, though, it’s comfortable enough. The soft fabric top can be slept on without sheets if you want, and there’s enough cushioning to keep you off the bumps and curves of your car’s seats. We do wish it had more of a headboard. If you aren’t careful, it’s easy to hit your head on a door handle. That makes for a rude way of waking up.
Our Thoughts
Sometimes simple is exactly what you need, and that’s what the FBSport inflatable mattress embodies. It’s perfect for the occasional night in a car. It’s not comfortable enough for extended stays or anything, but it beats trying to find a way to sprawl out across the backseats without a mattress. The simplicity also has another benefit; this unit is cheap.
The durability could be better, and sometimes the air valve will stick open, but it’s still a great value for the price. If you are still on the fence about buying a backseat bed, you can buy this without feeling bad.

Pros
Inexpensive
A good amount of comfort for what it is
Fits on most back seats

Cons
Could use a headboard
Air valve can be temperamental

3. Best Premium Pick: Pittman Outdoors AirBedz Pro3

View on Amazon
Why we like it: You’ll never want to sleep on another air mattress after spending a night on the Pittman Outdoors Pro3.
Editor’s Rating:

Fit
At almost 8ft long and over 5ft wide, the Pittman Outdoors Pro3 is the largest mattress on our list. That’s the same surface area of a king mattress. This means you’ll have no issues fitting a couple of people comfortably for a night of sleep (or other nighttime activity, we don’t judge here). It’s also the thickest mattress on our list, which means even if you load it full of people, they will all be comfortable.
The downside is that you need a ton of space to use it. It has cutouts for the wheel wells on a truck, and it’s wide enough that only larger trucks have enough width to make a good fit. You might be able to get it into a larger van, but the reality is that if you have anything smaller than an F-150 long bed, you’d be better off with a different mattress.
Finish
The mattress is a foot thick and has a soft fabric top. It’s easy to say that there isn’t a more comfortable bed on our list. The only thing you might want to do is bring an extra couple of blankets to fill the wheel well area completely. Just like the less expensive version we talk about on our list here, the wheel well cutouts can be just a little too large for many trucks.
The premium version here is a lot more durable than the less expensive counterpart, though. The pump is built-in and can run as soon as the air starts to leak out, keeping it inflated throughout the night, and the material is thick enough to withstand a lot of abuse. Without going completely airless and getting something like the Xprite mattress, you’d be hard-pressed to find a more reliable bed.
Our Thoughts
The Pittman Outdoors AirBedz Pro3 is a premium product, and it has a premium price tag. It carries an even higher price since you need a big truck just to utilize it, and those are never cheap.
It’s totally worth the price if you have a big truck and plan on spending multiple nights away from civilization. The leak-proof, fast inflating bed might even be more comfortable than your home foam and spring unit.

Pros
The integrated pump is fast
The large amount of area, perfect for two (or more) people
The thickest, most comfortable mattress on this list

Cons
Expensive
Only fits in the bed of a full-size truck

4. Most Versatile: Saygogo SUV Air Mattress

View on Amazon
Why we like it: Saygogo’s Air Mattress can be either a backseat mattress or an SUV/Van full-size mattress.
Editor’s Rating:

Fit
Saygogo chose to make this mattress all about fitment. It’s got footwell cushions so you can lay across the entire back of your vehicle uninterrupted. It can also fold up and be inflated in sections, converting it from an SUV style mattress to a backseat style bed.
There are not many vehicles that this bed wouldn’t fit into between the different chambers and the extra footwell cushions. SUVs, vans, and crossovers can easily fit the bed when it’s expanded and sleep multiple people. Small cars can use it as a backseat bed for a single sleeper, pets, or kids.
Finish
The very thing that makes it great also makes it less comfortable than some of the competitors. Each of those chambers is outlined by a deep seam that can cause a lot of discomfort if you get an arm trapped in them.
The thickness is good enough to be comfortable multiple nights, though. As long as you don’t fall into the crack, it’s as good as the Wey & Fly bed we recommend. It’s also fine in terms of durability, and is easy to clean. It’s not as strong as some, but it will outlast most cheap air mattresses.
Our Thoughts
If you aren’t sure about how big a mattress will fit into your car, then grab this Saygogo. It’s bound to fit in some configuration, and it’s wide enough to be used as just a backup guest bed on your floor, even if it doesn’t fit.
We do have a bit of an unusual criticism of the product, though. The ads, instructions, and online support are all terrible. Even the product page includes gems like “Get the warty. with email, a replacement or refund is allowed.” That’s not very confidence-inspiring, if something goes wrong, you are probably on your own. Not the worst thing to say about a product, since it does work, but it’s worth mentioning.

Pros
Versatile
The included pump can be powered in a variety of ways
Wide enough for larger SUVs

Cons
The seam can be uncomfortable when slept on
Documentation, like instructions and online-help, is terrible and full of poor English

5. Best Bed for SUVs: SuitedNomad Double Sleeping Pad

View on Amazon
Why we like it: SuitedNomad’s inflatable mattress is incredibly compact when deflated, so it’s easy to keep in your vehicle.
Editor’s Rating:

Fit
The SuitedNomad is big enough for two people who are comfortable with each other, and it fits most SUVs and Crossovers. In fact, at 4ft wide and over 6ft 5in long, it’s actually a bit bigger than other SUV mattresses.
You can even shoehorn it into smaller spaces. It’s flexible enough and thin enough to conform to nearly any space. The thin flexibility leads to its other big strength when it comes to fitment. You can roll it up to be super compact; it’s easy to justify taking on an adventure since you won’t be sacrificing cargo capacity.
Finish
Like the backpacking mattress we recommend, the SuitedNomad is very thin. That means that other SUV mattresses will be more comfortable. Ones like the Saygogo SUV mattress still fold up fairly compactly, are more comfortable, and just as versatile.
Almost nothing is more durable than the SuitedNomad, though. It’s got a soft cover that is stain resistant and thick enough to keep the rocks from puncturing holes in it. Also, like other thin mattresses, it’s very easy to inflate, even without a pump.
Our Thoughts
Compact mattresses work great for adventuring. They are better than sleeping on a hard surface, even if they aren’t the most comfortable things out there, and they are compact enough that they don’t take up any precious cargo room.
There are just two complaints we have about the SuitedNomad offering. First, it doesn’t come with a good pump. Getting a small, battery-powered pump will serve you a lot better than the bag pump that it comes with.
Second, in their effort to make it more versatile, the SuitedNomad mattress creators decided to chamber it. That makes it easy to fold in half and create a better condition for a single sleeper. Unfortunately, that means there’s a seam running the length of the bed.

Pros
Can either be inflated for one person or two people
Lightweight and extremely portable
Fits securely in the back of most SUVs and Vans

Cons
There are a lot of more comfortable mattresses
“Bag” pump has a high learning curve

6. Best Truck Mattress: Pittman Outdoors AirBedz Lite

View on Amazon
Why we like it: It may not be as thick as its more expensive counterpart, but the Pittman Outdoors Lite is still one of the most comfortable air mattresses you can get.
Editor’s Rating:

Fit
This behemoth of a mattress is only outclassed in size by its more expensive brother, the other Pittman mattress on our list. At 72in by 55in, it’s more than enough surface area for two people and a dog, and at 12in thick, it’s like sleeping on a cloud. A dense, fabric-covered cloud.
This is all fantastic, but only if you have a truck. Like the other Pittman Outdoors bed, the Lite version has cutouts for wheel wells and comes in sizes for short and long beds. You’ll have to double-check your truck bed dimensions, but if you have space, it will make a perfect bed out of your truck bed.
Finish
There are no seams to fall into, and the soft top is comfortable enough to sleep on without a blanket covering. You’ll still probably want one, though, just to keep it clean.
The only thing that might ruin your night is the wheel well cutouts. Unlike the thicker Pittman Outdoors bed, the mattress part that covers the wheel wells is fairly thin. If you roll into it during the night, you might sink down into the cavity. It’s nothing a few strategic blankets can’t fix, but it is something you’ll have to keep in mind.
Our Thoughts
If you have a truck and love camping, these kinds of air beds are the best thing you can get. Couple them with a truck bed tent or camper shell, and you’ve got RV level sleeping comfort for a tiny fraction of the price.
That means the only choice you have to make is whether you get the premium truck mattress we mention or this less expensive one. If you really need the ultimate in comfort, get the thicker Pro3 bed. You won’t be disappointed with the less expensive option, though. It’s still very comfortable, durable, and perfect for camping. Just bring an extra blanket.

Pros
Really comfortable
Big enough to fit two people very comfortably
Inexpensive compared to its rivals

Cons
Wheel well cutouts are too large
You need a truck with a wide bed

7. Best Compact Single Mattress: KingCamp Lightweight Sleeping Pad

View on Amazon
Why we like it: A backpacking roll makes a perfect car mattress to keep in your car for emergencies or a quick overnight trip.
Editor’s Rating:

Fit
It’s only 25in by 74in, which means it will fit in any vehicle with fold-flat seats. They do sell a double-sized version if you need to sleep two people, but the significant benefit to this mattress is the ultra-compact size. If you need to sleep two people, the Wey & Fly mattress costs less and is still reasonably compact when packed away.
Finish
Anyone that has ever been backpacking knows exactly how uncomfortable a backpacking mattress is. It’s better than dirt, but a lot is sacrificed in favor of the compact, lightweight construction. The only advantage of the thin design is that it only takes a few seconds to inflate.
It is long enough for most adults, so it may be more comfortable than backseat beds. It’s also super durable; it’s meant for backpacking after all. If you aren’t totally into ultimate comfort, there is really a lot to love about the KingCamp offering.
Our Thoughts
There are two mattresses on our list that are not car specific: the cheap, good enough Intex Dura-Beam, and this one, the KingCamp Lightweight. They couldn’t be more different, though. The Intex is thick, comfortable, and heavy. It’s also fairly likely to spring a leak since it’s made of thin PVC.
The KingCamp, on the other hand, is thin, made of durable fabric, and can easily be carried around in a backpack. That makes it perfect for people who do the occasional car camping or those who just want to keep an emergency bed around.

Pros
Very compact
Lightweight and easy to store
Easy to inflate

Cons
A bit expensive
Not the most comfortable thing out there

8. Best for Smaller Cars: Caloer Thickened Inflatable Car Air Mattress

View on Amazon
Why we like it: If you have a smaller car or hatchback, the Caloer mattress is the best inflatable car mattress you can get.
Editor’s Rating:

Fit
Like any backseat bed, the Caloer offering comes with two big inflatable pillows that take up the wheel well space and give you a full 34in of width to stretch out on. That’s about the size of a twin mattress, which isn’t enough room for two people but sure as heck beats sleeping on the narrow seats.
It’s also chambered, and the footwell supports detach and can be inflated to different levels. What that means is it’s actually more likely to fit your car than the less expensive FBSport backseat mattress. Still won’t fit into a subcompact or sports car, but everything bigger than a Yaris will have no issue.
The only thing you’ll really wish is that your car was another foot longer. At just over 4ft wide, you will need to employ the fetal position if you are average height.
Finish
It’s in the finish and comfort that the Caloer shines. It’s got extra inflatable cushions to protect you from the bumps and corners of your car. A big side cushion prevents you from rolling onto your center console, and the extra tall headboard will prevent your head from making contact with the door handle.
The Caloer is thicker than other backseat airbeds, and it’s covered in a no-slip fabric, which makes it a lot quieter than, say, the fairly noisy FBsport mattress. All in all, it’s about as nice a bed as can be made in the back seat of a car.
Our Thoughts
What kills the mood when we talk about any backseat bed is the part when we talk about the length. A full-sized adult will never be comfortably crammed into the back area of the cabin. If you have to do it, though, the Caloer mattress is the best way.
It’d better be, though, since you could buy 3 of the FBSport mattresses for the price.

Pros
Durable
Has extra cushions for a headboard and sideboard
The seamless mattress is more comfortable than many competitors

Cons
Expensive for a backseat air bed
Still too short to be a great alternative to a real bed

9. Best Basic Air Bed: Intex Dura-Beam Standard

View on Amazon
Why we like it: There’s no reason a standard air mattress can’t be used inside a car, and the Intex Standard is a very budget-friendly one.
Editor’s Rating:

Fit
It’s a full-size mattress and is not explicitly built for vehicles. The good news is that since it’s not specific to any vehicles, it will fit anywhere with a 53in by 75in space. Camper vans, RVs, big SUVs, flat truck beds, you name it.
A full-size mattress is bigger than every SUV-specific bed on our list, even the highly-rated Wey & Fly offering. That does mean it won’t fit into smaller SUVs, crossovers, or wagons. They do sell a twin sized version if you don’t have space for the full-sized one.
Finish
Let’s be real here: it’s a cheap air mattress. You can probably picture exactly how it feels already. It’s got a weird, pseudo fuzzy top and makes weird noises when you roll around on it. The thickness and width make it really comfortable, though, so it’s hard to hate.
Just definitely don’t expect it to last forever or anything. It’s a cheap air mattress, it will last you through the night, and if you are lucky, it will stay hole-free for a year or so.
Our Thoughts
There’s no reason not to just get a comfortable, cheap air mattress if you have space. The battery-powered pump works anywhere, and the extra size means that you can comfortably sleep two people.
It simply has all the drawbacks of a cheap air mattress too. It’s not a good thing to rely on in an emergency, and it doesn’t have wheel well cutouts or any other features. The battery pump is worth the price alone. If all else fails, you can keep the pump and use it to fill up any of the other mattresses we recommend, like the nearly indestructible SuitedNomad Double.

Pros
Inexpensive
The battery-powered pump is great for travel
Versatile

Cons
No features that make it better for cars
Quality could be better

10. Best Foam Car Bed: Xprite Black NitePad Premium

View on Amazon
Why we like it: The Xprite mattress is a giant foam mattress that pieces together to fill the back of your SUV. It is super comfortable.
Editor’s Rating:

Fit
The Xprite is perfect for most larger crossovers, wagons, and SUVs. At a little under 42in wide and coming in at 70in long, it’ll fit very comfortably in the back of any minivan or SUV, and will fit snugly in the back of CUVs like the Outback and Rav4. They also make a version specifically for the bigger Wranglers, so grab that one if you own a Jeep.
It’s a little tight for two people, but 70in is the height of most doors. If you fit through your front door, the length won’t be an issue, which is nice.
Finish
The Xprite is a bit different than everything else on our list because it’s not an airbed. That does have some drawbacks. Creases run rampant throughout the unit; you can definitely lose an arm between cushion segments that might lead to uncomfortable sleep.
Generally, though, it’s going to be more comfortable than an air mattress of the same thickness. The foam is covered in an easy to clean leather-like material, and the best part is that there is zero chance of springing a leak. Even if you forget to take your boot knife off after a long day of cutting trails, there will still be enough mattresses in the morning to protect your back.
Our Thoughts
There are two reasons to avoid the Xprite NitePad, and they really highlight the advantages of an airbed. First is the price. Even the incredibly luxurious Pittman Outdoors Pro3 air mattress is cheaper. What makes that an extra tough pill to swallow is the Pittman’s comfort far outpaces the Xprite’s; the Xprite just isn’t thick enough to compete.
That brings us to problem number two. The Pittman Outdoors bed is much bigger while inflated, but much, much smaller deflated than the Xprite. Even though the Xprite folds up, it’s easier just to throw all your cargo on top of it and pretend it’s the floor.
The simple fact that it can’t spring a leak might make it the right choice for any overlander, though. Off-road trails are never gentle, so the peace of mind that your mattress will support you at night can definitely be worth paying extra.

Pros
Very comfortable
There’s no chance of an air leak
Easy to clean

Cons
Really expensive
Takes up a lot of space, even stored

Advice, Accessories, and Alternatives
Now that you’re ready to get a good night’s worth of rest in your car, there are a few things that can really improve the experience.
Making Sure it Fits
Don’t worry, you don’t need to measure every inch of your car. You just need to know a few things so you can make sure that the air bed you buy will fit in your car. First, and most importantly, you need to know what kind of vehicle you will stick the bed into. Generally, a bed made for an SUV will fit in most larger vehicles like crossovers, CUVs, and minivans without much trouble.
The other thing you will need to know is the general width, length, and height of the space you will be putting the bed in. Length is the most important measurement, especially for truck bed mattresses. Simply fold your seats down or measure across the back seat so you know the maximum size you can get.
Accessories
To get the most out of your experience, there are some items you should take with you. Most you will already have, but some simple things can be purchased for cheap and really help out.
A pillow. Even though most air beds, including the less expensive mattresses like the Fly & Wey we mention, have inflatable pillows. They are usually pretty bad, so grab your own instead.
A repair kit. The Saygogo, and many other mattresses, come with one, so you might be fine. If not, grab one here. They are cheap, and they are wholly necessary if you are doing multi-day expeditions.
It’s a bit obvious, but you probably want to be warm when you sleep.
You should have water in your car no matter what, but especially if you are planning on spending the night. You lose a lot of water when you sleep, and it’s a good idea to replenish it before continuing on your journey.
Tips
There are a few tips and tricks to help you get the most out of sleeping inside a vehicle. The first thing, though, is perhaps the biggest piece of advice we can give you.
Make Sure to Sleep Where It’s Legal
In most cities, you aren’t allowed to pull off to the sidewalk and sleep the night. If you don’t want to be woken up by your friendly neighborhood police officer, then take a look at local laws before you jump into bed. You can get a bit more information about the legalities of sleeping in your car right here.
There are a lot of spaces that you know will be safe, though. Campsites and dispersed campgrounds are the obvious ones, but most rest stops, Walmart parking lots, and anywhere labeled BLM (Bureau of Land Management) land are good places to park for the night and catch some shuteye.
Additional Tips and Tricks
Once you are sure that you don’t have to face the red and blue flashing sunrise, there are some great things to do to make sure you are as comfortable as possible.
Park so your head will be uphill if you can’t park where it’s level. It makes a big difference for long term comfort.
Be aware that the first time you use an air bed, it will seem like it leaks a lot of air. That’s not the case; it’s just stretching and forming. Re-fill it and try it again before assuming that it’s leaking.
Consider grabbing a battery or foot pump for backup. It beats trying to fill the bed with your lungs if the main pump goes out.
A sheet layer underneath an air mattress can eliminate a lot of squeaks and noises.
Extreme cold will deflate your bed as you sleep on it. If you are snowbound, consider a foam mattress like the Xprite bed we recommend.
Crack the front windows for a little bit of venting. That will keep the air from getting too stale and uncomfortable.
Tell people where you are. If something should happen and someone needs to find you and your car, it’s better that they don’t have to search for too long.
Alternatives

If you read all about air beds and are still not convinced they are for you, then no worries. There are some great alternatives.
Rooftop Tents
We talk about them at length here, but rooftop tents are probably the best alternative to an RV that you can get. They usually come with their own mattresses and mount to almost any vehicle. That way, you can keep your cargo bay for cargo and still maximize your comfort. Truck owners can also find some great tents that fit in the bed of a pickup truck.
Built-in Beds
Whether we are talking overlanders, van-lifers, or the RV crowd, the people who absolutely must rely on a comfortable bed inside a vehicle all have custom-built mattress frames and pads. They cost a lot, but if you plan an expedition across the states in a van, we guarantee it’s cheaper than paying doctors to repair your spine.
Pile of Blankets
The last alternative we’re going to talk about is also the most accessible, but probably the worst for your back. Pillows and blankets can be laid out to make a perfectly acceptable sleeping pad. You will have to contend with the footwells in the backseat area of most cars, and you will have to contend with lumps and pillars in the back of most SUVs. It’s better than just sleeping on the carpeted cargo area, but when an air mattress like the FBSport is the cost of a few lunches, there’s no reason to suffer like that.
Sleep Tight
Whether you are camping or just hiding from your in-laws, a car bed can be the difference between a world of sore muscles and pleasant dreams. Grab one for yourself. Even if you don’t see yourself ever sleeping in your car, they make great extra sleeping spaces for pets and children when you are on the road. They also make a good contingency plan for when everything goes to hell, and you need to survive the Mad Max apocalypse. Just, let’s not hope that happens, no matter how cool the cars seem. More

Hopefully, it isn’t a surprise to anyone, but oil is supposed to stay inside your car and not leak out. If it does escape, it’s a pain. An oil leak can cause your car to smoke and makes a mess of your engine compartment, as well as your driveway. The good news is that there’s a variety of products made just to stop leaks. They are fittingly called “stop leak additives.”

Choosing the Right Way to Stop a Leak
There are a lot of brands that all make a product meant to stop leaks. Every single one of them claims to be the best. The truth is that there is no universal best. There are some products that work better in some situations, and there are some that work better in other situations. The best way to get the most out of an additive is to choose the one that works best for the problem you are having.
Small Leaks Only
Here’s the thing with stop leak additives: they don’t work on big leaks. They also only work on certain types of materials. Leaks from cracks in metal, leaks from pressed-in fittings, and leaks from loose parts need to be fixed. No amount of liquid gunk you pour into your oil will magically weld a crack shut. If you see a few drops weeping from an old gasket, though, they are perfect.
Leak Location
Where the leak is coming from is probably the most important thing to know when choosing an additive. If you head over to Popular Mechanics, they have a quick guide for finding out what component on your engine is leaking. You don’t actually need to be perfectly accurate, just the general area is fine. A head-gasket leak has a different set of rules than a main seal when it comes to stop-leaks; it doesn’t matter the exact location of the hole.
Internal Leaks
External leaks are easy to notice. The oil will be on the outside, either coating your engine bay in slime or staining your garage. An internal leak, where oil is getting into the cylinders or cooling system, is much more subtle. Some oil stop-leaks can solve an internal leak, but usually, if you suspect oil is getting into internal components, you are looking at a visit to a mechanic or a few long nights under the hood.
Oil Being Burned
The biggest symptom of an internal oil leak is blue or dark gray smoke coming out of the exhaust. When oil gets into the cylinders, it burns and colors the escaping gases. Unfortunately, while it can sometimes just be a leaky gasket, it’s more likely that there is a mechanical seal that is not working correctly, and you need to open the motor up.
Oil in the Coolant
Oil in the coolant system, and much more noticeably coolant in the oil pan, is a bad head gasket symptom. If there is some cross-contamination and your car is belching out white smoke, stop driving the car. A stop leak will not help you if the coolant is getting into the cylinders.
Gas or Diesel
One final consideration is the type of fuel your car uses. Some additives won’t work with some fuels. Most of the time, additives are formulated for all engines, but there are a few special cases.
Alright, let’s get down to business. Here are our thoughts on 10 of the best stop leaks out there. Most are simple enough to use; just pour them into your oil reservoir at whatever ratio it says. Some are a bit more complicated, but all of them are good products.

Top 10 Best Oil Stop Leak Additives 2020
1. Best Overall Pick: Lucas Oil Stop Leak

View on Amazon
Why we like it: Lucas is a household name in automotive for a good reason: they make products that work.
Editor’s Rating:

Leaks Fixed
The Lucas is great for weeping gaskets. If you have a slow leak on the oil pan or around valve covers, it’s perfect. If it’s a big leak, don’t bother.
Any Compatibility Issues?
Many people seem to believe that Lucas Stop Leak won’t work with diesel engines, but Lucas says there’s no issue. What it may have an issue with is other additives; just make sure it’s the only thing that isn’t oil you put into your oil pan.
Verdict
Lucas Oil Stop Leak is more than just a gasket fix, and that’s why we call it the best. It quiets the engine down, reconditions oil, and unlike many additives, you don’t have to make sure to drain it out after a while. It’s safe for your engine, and only the BlueDevil stop leak rivals it in terms of total compatibility with petrol-based products. You can use it in any oil, with any engine, and feel ok. It also doesn’t cost much, per ounce, it’s one of the cheapest products on our list. So there’s that.
It’s not a miracle substance, though. For one thing, bigger leaks need filler. Lucas stop leak doesn’t have any filler in it. That makes it super safe, but makes something like the Bar’s Rear Seal stuff better for bigger problems.
There’s also this pervasive theory that you shouldn’t use it on a diesel engine. No one seems to be able to say why, but it does cause some people concern. It’s ok to get the BlueDevil instead if you can’t shake that feeling.

Pros
Improves engine performance in addition to stopping leaks
Very safe to use
Inexpensive

Cons
Not good for bigger leaks
Doesn’t play well with other additives

2. Honorable Mention: BlueDevil Oil Stop Leak

View on Amazon
Why we like it: BlueDevil is another highly trusted product that works great. It’s considered a safer product than the Lucas additive, but it doesn’t work as well on large gaskets.
Editor’s Rating:

Leaks Fixed
BlueDevil’s forte is pinhole leaks and tiny cracks. While weeping gaskets are better solved with the Lucas stop leak, BlueDevil is better at stopping a leak with visible drops. It’s a very long-lasting product, so the best leaks to fix are ones you don’t plan on addressing in the future. It’s still not magic, though, so don’t expect it to fix bigger issues.
Any Compatibility Issues?
No, like the Lucas, the BlueDevil contains nothing that can interact with normal engine operation. In fact, it doesn’t have the stigma of being incompatible with diesel motors. If that’s what turned you off from the Lucas, then this is a good alternative.
Verdict
There’s only one thing that prevents the BlueDevil stop leak from being #1, and that’s the price. It’s virtually identical in function to the Lucas product, but it costs a bit more. That being said, it’s still an excellent product. If you just like the blue bottle better, or don’t like Lucas, it’s going to get the job done, and you’ll be happy.
It does take a bit more time to use than other products if you do it by the book. Which let’s be clear, you should always read and follow instructions when it comes to adding things to your engine. BlueDevil suggests going through the process twice to make sure leaks are taken care of, which means it takes twice as long as others like Bar’s stop leak.

Pros
Works with all engines
Stops pinhole leaks
Long-lasting

Cons
Costs more than similar products
Takes a little longer to use than similar products

3. Best Premium Pick: Bar’s Leaks OS-1

View on Amazon
Why we like it: Bar’s stop leak is one of the best working sealer additives on the market.
Editor’s Rating:

Leaks Fixed
Any time a seal gets old, it has a chance of developing a leak. That’s because it dries out and shrinks a bit. Products like the Lucas get absorbed and work quickly to expand the seal, making it perfect for slow seeping leaks, and the BlueDevil works by expanding over time so that it can close off bigger holes. Bar’s does both, making it perfect for older engines that have a lot of leaking all over the place. It won’t fix a big crack, but it will allow you to finally clean your engine bay.
Any Compatibility Issues?
Bar’s doesn’t sell products that have compatibility issues; it’s something they are known for. You do pay for that peace of mind, though.
Verdict
If you are not sure what product to get, get this one. It costs more than the others, it comes in an intimidating bottle, and it has funny words printed on the box. Ignore all that. Bar’s Oil Seal has the best chance of working on small leaks. They also sell a product for bigger leaks, the Bar’s Rear Main Sealer, but that’s even more of an intimidating product to use. Stick with this. It’s easy to use, works for older motors, and won’t damage turbos. If it doesn’t work, save up for a replacement gasket.
Just be aware of two things. First, it doesn’t work as fast as the Lucas stop leak. You’ll need to wait for about 200 miles worth of driving time for it to really show good results. Second, it costs four times as much as the Lucas but isn’t really that much better. It’s more of a psychological thing; it costs more, and has really fancy words printed on it, so you’d think it was way higher quality. The truth is that it’s not that much different. We said it was the most likely to work, and we stand by that, but you might kick yourself if you found out later that the cheaper products would have worked just as good.

Pros
Works with any motor
One of the best working stop leaks on the market
Is good for older motors

Cons
Costs more than other products
Takes a while to activate and work

4. Best for Stopping Smoke: Liqui Moly 2020

View on Amazon
Why we like it: If your car is producing blue smoke, it’s burning oil. Liqui Moly is specially designed to make it stop.
Editor’s Rating:

Leaks Fixed
Liqui Moly is an excellent product for internal leaks. Bad seals on the inside of the motor lead to excess smoke and can cause you to fail inspection. If you see the telltale blue smoke rising from your exhaust, this product can save you a costly visit to a mechanic.
Any Compatibility Issues?
There is one, and it’s a bit of a weird one. Don’t use it on vehicles with a wet clutch that have a shared oil reservoir. If you don’t know what it means to have a wet clutch, you probably don’t have one. It’s rare. Many motorcycles have wet clutches, but the chances of the average driver encountering one are slim. We just have to say it.
Some websites also note that you shouldn’t use it with an automatic transmission: that’s not true. What you shouldn’t do is add it to your transmission. That’s true for most stop leaks unless they specifically say they are for automatic transmissions.
Verdict
Liqui Moly is German, and it fits right into the Mercedes and BMW precision engineering philosophy. It even looks like it belongs on a shelf at a BMW shop. More than anything else, the Motor Oil Saver is all about keeping the insides of your motor healthy. The Lucas improves motor function as a byproduct. It’s a gasket sealer first, and a stabilizer second. The Liqui Moly is all in on the stabilization and lubrication aspect.
It works fantastic if you are burning oil. It also works fantastic if you seem to be losing oil, but can’t see any leaks. It’s not as good at sealing gaskets, though, so if you see evidence of a leak on the outside of the motor, you are probably better off sticking with BlueDevil or Lucas.

Pros
Great at slowing or stopping engine oil consumption
Good for making your car run cleaner
Liqui Moly is a very high-quality brand

Cons
Some compatibility issues
Not as good at stopping external leaks as other products

5. Best Budget Pick: STP High Mileage Oil Treatment

View on Amazon
Why we like it: It costs so little it’s hard to care about the fact that it isn’t the best at stopping leaks.
Editor’s Rating:

Leaks Fixed
It will fix really minor leaks. If you have a dribble, get the BlueDevil, and if you have a lot of weeping, get the Lucas. But if you have an old car with mystery stains from oil that seems to have no origin, this stuff is probably all you need. It will help stop smoking too. Not like cigarettes, that’s a different journey, but high mileage engines sometimes leak a little oil into the cylinders. The STP will help manage that.
Any Compatibility Issues?
If you follow the directions, there are no issues. However, and this is important, if you add too much of the product and dilute the oil, you can risk damaging your engine. It’s a very thick product and can make your oil a little slimy if you use too much. That slime will clog channels and make the engine work harder.
Verdict
STP is a well-known oil product manufacturer, and unlike the band, they are still putting out great products. This high-mileage treatment is one of them. It’s for, as you probably guessed, high mileage motors. It’s also amazingly cheap, easily half the cost of any other additive on this list.
It works well if you use it to stop very slow leaks on older cars. Think of the STP treatment more like an oil thickener than something that will plug a hole. Imagine trying to pour molasses through a colander, and you’ll get it. The downside is that it’s not great for reconditioning seals, especially not compared to Bar’s Stop Leak. Granted, as we said, it’s much cheaper.
It’s also a little bit dangerous if you just use it willy-nilly. Unlike products like the Lucas that don’t dilute the oil, the STP treatment will eventually become concentrated and cause problems if you just keep adding it. Do an oil change more often, and you’ll be fine.

Pros
Good for high mileage engines
Inexpensive
Helps an older car stop smoking

Cons
Can dilute the oil if used improperly
Not as good at reconditioning seals as other products

6. Best Main Seal Repair Additive: Bar’s Leaks Concentrated Rear Main Seal Repair

View on Amazon
Why we like it: Bar’s Rear Main Seal Repair is great if you suspect a leaky main seal. It’s specially formulated for rubber seals and works quickly.
Editor’s Rating:

Leaks Fixed
The name suggests that it’s only for main seals, but it’s actually suitable for just about any gasket or seal. What it’s best for, and what sets it apart from everything else on the list, is medium-sized leaks. Since it is a relatively thick and heavy-duty concentrate, it can really get into cracks and issues and close them up.
Any Compatibility Issues?
There should not be any compatibility issues. As with the other Bar’s product we have, making it easy to use, worry-free products are tied to their brand identity.
Verdict
This is the one product to try after other products have failed. It can close larger holes than anything else on this list. There aren’t many downsides to it either; it’s just more hardcore than most people will need.
All stop leaks carry risks. Risks like clogging channels or causing a leak to worsen due to the type of damage a seal has suffered. This concentrate just has a greater risk of all that compared to everything else. It’s more likely to work, and also more likely to cause problems. That’s why we say to try it after something else fails. It’s probably your last chance to solve the problem before having to take off the part and change out the gasket.

Pros
Fixes larger leaks
Compatible with all engines
Works quick

Cons
Small risk of clogging oil channels
Will make improperly installed gaskets leak worse

7. Best Fast-Acting Leak Stopper: ATP AT-205

View on Amazon
Why we like it: The AT-205 is a simple, fast-acting product.
Editor’s Rating:

Leaks Fixed
This is another one of those general-purpose sealers. The “I’m not sure where the leak is coming from, but it’s slow enough not to cause a panic,” type of leak that you think could be a valve cover or could be a worn-out oil cooler line, but you don’t really care to find out which. The only thing that makes it different than the Lucas or similar products is that it’s formulated to be better on plastic parts. Your ‘90s-early 2000s import cars will be happier.
Any Compatibility Issues?
There is one issue to be aware of when looking at the ATP. If there’s gunk in your oil pan already, like some engine sludge or other contaminant, it may dislodge the gunk and clog things up. The chemical that makes it useful for restoring gaskets is also really good at dissolving particles like paint, so just be aware of that. Read the directions and use less than they recommend at first. If it fixes the problem using less, you have no problem and didn’t risk clogging your oil pump.
Verdict
ATP makes a good product. It’s not as good as the Lucas product, and it costs a little more per treatment. However, if you own a car with many plastic parts, you may find it’s more useful to have the ATP over anything else.
The thing with the ATP is that the chemicals that make it good for polymer seals can also make it bad for your car. If a gasket is rolled or improperly installed, it will do its job and make them swell. That will make the leak worse. It will also strip the paint off your car if you accidentally spill it, so don’t do that.

Pros
Works well on cars with a lot of plastic parts
Good for minor leaks
Works faster than similar products

Cons
There’s a chance it will make the leak worse if the gasket is damaged
Should only be used if you know the oil is clean

8. Best for Head Gaskets: BlueDevil Head Gasket Sealer

View on Amazon
Why we like it: It’s specially formulated for head gaskets. That means if it works, it can save thousands of dollars in repairs.
Editor’s Rating:

Leaks Fixed
There are few phrases that spark fear into the hearts of mechanics. At the top of the list are terms like rod-knock, lifter noise, and blown head gasket. It’s that last one BlueDevil is attempting to solve.
This is a product meant to stop coolant from getting into the cylinders. You don’t pour it into the oil pan. You pour it into your radiator. We chose to include it on a list of oil stop leaks because one, head gaskets can leak oil as well as coolant, and two, these kinds of problems are all connected to each other. Chances are if you have a bad gasket on the bottom end, you have a bad gasket on the top end too.
Any Compatibility Issues?
Tons. We hate to say it, but there are just a ton of compatibility issues anytime you deal with coolant. Since it’s pretty much impossible to know how a product will react with every single one of the hundreds of coolant and radiator types, the best thing to do is to drain and flush the coolant system before attempting to use this product. That’s a tall order, but it’s way better than clogging a tiny coolant vein. The good news is that BlueDevil makes everything you need to do it, and they all work with each other.
Verdict
The simple truth is that there’s no such thing as a perfect liquid head gasket fix. There are temporary solutions that work fine, and there are products that won’t work at all. Even products like the BlueDevil that work on some vehicles may not work on yours. What you are paying for is the chance that you will only have to buy a product that’s around $50 instead of paying a mechanic several thousand.
The earlier you can catch a problem, the better chance you have. If you notice excess smoke from your exhaust, first try a product like the BlueDevil oil stop leak. If the problem persists past 500 miles or so, then start diagnosing a blown head gasket. Don’t wait with head gaskets, and honestly, don’t put all your faith into a head gasket sealer. It will cost you a lot of money if you let the heads warp because you waited too long.

Pros
Can save you thousands of dollars
BlueDevil makes a full line of products to help you along the way that are all compatible with each other
Helps with leaks everywhere on a coolant system

Cons
It might not work for you depending on thousands of hard to predict variables
It takes a long time to do it right

9. Best Emergency Stop Leak Spray: Permatex Spray Sealant

View on Amazon
Why we like it: A different approach to the problem of leaks, the Permatex Spray Sealant lets you patch up small leaks from the outside.
Editor’s Rating:

Leaks Fixed
Any small leak that you can see from the outside. It doesn’t matter what liquid is leaking, and it doesn’t matter what material it’s leaking out of. The Permatex Spray just coats the area in a goo that hardens and creates a barrier.
Any Compatibility Issues?
None. Since you spray it on the outside of the leaking component, it doesn’t actually have any interactions with the inside of the motor.
Verdict
The Permatex is another product like the RTV that isn’t something you add to the oil, but it is a good thing to have in your tool kit if you are trying to fix a leak. Unlike the RTV, it’s incredibly simple to use. You clean the leaking area, shake the can, and spray the contents at the leak. It hardens into a new seal and dams the liquid inside.
It’s only a very quick fix, though. The hard barrier will be in the way of future repairs, and it will have to be chiseled off, which is a pain in the butt. Basically, use this stuff if you don’t have any other options. Like you are out on the trails and just need to keep it together for another 30 miles until you make it back to civilization or something.
It can be picky sometimes. You have to clean the area pretty well so the goo can stick to the surface. Even then, sometimes, conditions are wrong and it won’t form a good barrier. This just adds to the idea that it’s only a good thing to use if you don’t have any other options and nothing to lose by trying.

Pros
Great for an emergency fix
Works on a lot of different surfaces
Easy to use

Cons
Terrible for a long-term solution
Sometimes it just doesn’t work

10. Best for Big Leaks: Permatex Ultra Black

View on Amazon
Why we like it: Sometimes, a stop leak can’t fix the problem, and you have to get serious. That’s where an RTV sealer comes in.
Editor’s Rating:

Leaks Fixed
Unlike everything else on this list, RTV sealer is good at fixing big leaks. That’s because it’s not a product that fixes an old gasket. It’s a product that is used to create a brand-new gasket. Yes, that means it takes a ton of work, but if you are in a situation where you can’t get a new gasket, you don’t have much of a choice when the leaks get too big.
Any Compatibility Issues?
There aren’t really any compatibility issues. Permatex sells other sealers that are better for different applications, but since this article is all about oil leaks, we choose to feature the Ultra Black. The Ultra Black is all about oil resistance, and that’s everything you could want.
Verdict
Gasket makers are something everyone should have in their toolbox if they work on cars. There’s a lot of stupid reasons you’ll need it. Like if you are replacing a part and accidentally destroy the gasket, or you just need your beater to stop dripping oil on your driveway.
It just takes a lot of work to use it right. Unlike the spray sealer, RTV goop takes a ton of prep and is in no way a quick fix. You have to take the part off, clean it, scrape all old gasket residue off, apply the product, then bolt the part back on before the stuff dries. It’s messy, it’s in no way better than buying the right gasket, and if you have to take the part off again, you’ll be kicking yourself.

Pros
Can fix any oil leak eventually
Unlike most stop leaks, it’s actually a long-term solution
Makes a strong, durable seal

Cons
Takes a lot of time to use
Only a good replacement for a new gasket if you can’t get the new gasket

About Stopping Leaks
Most stop leaks are straightforward, but there are tips and tricks that everyone can use to make sure they get the most out of the product.
Understand the Limitations of Stop Leak Additives
We went over it before, but we’ll do it again. If you experience big leaks, broken components, and cracked lines, none of those can be fixed by adding something to your car. Spray sealers like the Permatex can work temporarily, but nothing will actually fix the problem until you repair the damaged part.
Beware of Diluting Your Oil
Oil additives are not motor oil and do not perform the same function. Even Lucas, who prides themselves on being great for motors, will be bad for your engine in sufficient quantities because it will dilute the oil. As a general rule, only use a product once per oil change. However, like BlueDevil, some products recommend using the product twice if the oil doesn’t stop leaking the first time.
That brings us to our most important piece of advice…
Read the Instructions
Read the instructions and follow them. It’s impossible to overstate the embarrassment you will feel if you bought a head gasket sealer meant to go into your coolant, and you put it into your oil.
Treat All Additives as Temporary
Even the BlueDevil and Liqui Moly that claim to be permanent are not. In truth, even a gasket maker like the RTV is not a permanent solution. You should always plan on eventually getting the correct gasket and installing it.
When a gasket or internal part wears out, it’s only going to get worse over time. A stop leak works by being absorbed into the area around the leak and then expanding. It can only work where it can be absorbed. That means there’s still a lot of the gasket that is not functioning correctly, and over time the same process that caused it to fail in the first place will happen again.
When it happens again, the likelihood of a stop leak working is significantly lower.
Prevention Is the Best Way to Stop Leaks
Keeping your oil clean will keep your internals from wearing down and leaking. That means keeping up on your scheduled maintenance and using the right oils. Heads usually fail due to heat, and lines can deteriorate if the vehicle sits unused. Basically, and bluntly, the most common reason that a car develops a leak is neglect.
FAQ
We see a lot of questions about stopping oil leaks being asked around the web, so here are some answers.
Are Stop Leak Additives Safe?
Yes. Old additives use chemicals that could cause clogs or corrode materials, but modern stop leaks are safe. You can read all about what modern stop leaks are made out of here if you’d like. In short, assuming you follow the directions, your car will be safe if you use these products.
Can You Use Oil Stop Leaks for Transmissions?
Sometimes you can. Some additives are perfectly safe for transmissions, like the AT-205 Re-Seal. Some are not, like the Liqui Moly. If you have a leaking transmission, though, it’s probably better to buy a product specially made for transmissions.
Can Different Stop Leaks Be Used Together?
In general, no. While it may not cause a problem immediately, it may dilute the oil and cause future problems. It is also not worth it; most of the time if a product doesn’t work, it’s because the leaking part has failed. It’s not because a different product would be more effective.
How Long Should You Wait Before Deciding a Stop Leak Didn’t Work?
If a product is going to work, it will work after driving 500 miles or so. It does vary product to product. For instance, the BlueDevil additive takes longer to activate than the ATP, but both should be at full strength by the 500-mile mark. If you still have a leak after 500 miles, you probably need to look for a new solution.
Stopping Leaks Keeps the Stains Away
No one likes to try to clean oil out of concrete, and no one likes to scrub oil out of an engine compartment. For the sake of sanity, grab some oil stop leak additive and keep the leaks at bay. You should also consider picking up an oil drain pan to protect your garage floor or driveway while you sort out your leak problems. Also, consider using laundry detergent to scrub oil stains out. It works great. More
