1. K&N – Best Cold Air Intake for Jeep Liberty 3.7L

K&N Cold Air Intake Kit: High Performance, Increase Horsepower: Compatible with 2010-2012 Jeep/Dodge (Liberty, Nitro)

What are you looking for in a replacement intake kit? Is it strong protection against contaminants, a better engine sound, or maybe an improved airflow? Good news: you’ll get all of that with the K&N cold air intake. Thanks to the patented High-Flow air filter, the engine will be safeguarded from the tiniest dust, pollen, and allergen particles, not to mention debris. The engine’s tone will be boosted as well.

As a result of the increased airflow, the motor will get that roaring characteristic that most off-roaders like. Speaking of the airflow, expect an up to 50% improvement. So, you can stop worrying about engine failure, because overheating won’t be an issue with this gear. On the downside, the price-tag of this intake system is a bit steep. It’s not unreasonably high, though.

If you’re looking for the finest aftermarket cold air intake for the Liberty, K&N might have the right offer for you. Thanks to the advanced anti-contaminant protection, strong airflow, and a “beefed up” sound, this air kit improves the powertrain in more than one way. But, you’ll have to pay a big buck for it.

2. AEM – Best Cold Air Intake for 07 Jeep Liberty

AEM 21-8309DP Polished Brute Force Intake System

Feeling a bit patriotic? Then pay extra attention to the AEM cold intake. This is a 100% US-made product. They designed, built, and, most importantly, dyno-tested it in the States. Besides, it was engineered with the Jeep Liberty in mind, meaning it will be very easy to install. The replacement/mounting process will take you two hours at a slow pace with no extra hands and only a set of basic tools.

The overall construction is decent as well. The housing comes with a heat shield (blocks hot engine air) and weather stripping (keeps cool air from “running away”). Sadly, the performance improvements are very modest and you probably won’t even feel that big of a difference. On the bright side, this air kit does boost the airflow quite nicely.

Verdict

Easy, no-hassle installation, weather stripping, and decent gains in the airflow are this cold air intake’s biggest selling points. It’s a US-made product, by the way, designed and crafted for the American roads and the Liberty. The increase in performance won’t be very impressive, however.

3. Auto Dynasty – Best Replacement Air Intake Kit for Jeep Liberty 2003

Compatible with 2002-2003 Jeep Liberty 3.7L V6 Aluminum Lightweight Hi-Flow Air Intake Kit

Next up, we’ve got another third-party cold air intake kit worthy of your attention. It was engineered from the T-6061 aluminum – one of the sturdiest, most reliable, and flexible materials on planet Earth. The kit is lightweight, durable, and long-lasting. Plus, compared to the stock system, you’ll see an increase in fuel efficiency. Depending on your vehicle’s engine, transmission, and suspension, you’ll end up with 1-2 extra miles per gallon.

In the long run, that will save you enough money to buy a new air kit. Keep in mind, however, that the installation process might not run very smoothly. Again, this has to do with your Liberty’s engine, model year, and other parameters. Mainly, the issues are with fitment: you’ll probably have to bend the heat shield a bit for the air kit to fit the factory mounting holes. Or, drill in new holes, if you’ve got the right tools.

4. DNA MOTORING – Best Cold Air Intake System for 2012 Jeep Liberty

DNA MOTORING AIPBK-CC57L-RD Short Ram Air Intake

Owners of the 2012 Liberty (the most recent model before it was discontinued) might want to pay extra attention to the DNA Motoring cold air intake. It goes great with the latest Liberty and does an excellent job of improving its performance. The built-in filter is pretty decent as well and you won’t have any problems with cleaning it whatsoever. It is washable (with water and some soap) and reusable.

Now, while the overall build quality isn’t on par with the most expensive cold intake systems, it is still rather solid. Besides, DNA’s selling it for cheap: this is one of the least expensive aftermarket air kits right now. So, folks on a budget will definitely like it. As for the cons, the package only includes an intake tube, a filter, and some installation hardware. You won’t get any type of housing.

Best Cold Air Intake for Jeep Liberty

Verdict
Ask Question

Affordable, well-built, and perfectly compatible with the Liberty SUV, this cold air intake system can be a very good investment for you. Just remember that it doesn’t have a heat shield and might not handle the most stressful off-roading trails. On the other hand, If you only drive on mildly challenging roads, that shouldn’t even be a problem.

Buyer’s Guide

Alright, with my list of the finest cold air intakes for the Liberty out of the way, it’s time for some theory. Don’t worry: I won’t get into any of that boring stuff. Instead, we’ll focus on the key points to look for when buying a new air kit.

Compatibility and Fitment

I want to say right from the start that there are no universally compatible cold air intakes. They all fit a small list of vehicles, which is why you need to find a kit that’s 100% compatible with your Liberty. When I say “your”, I mean the exact make, model, year, and engine. Some air intakes are great for four-cylinder engines; others go hand in hand with V6 units. So, the first thing to check is whether it is going to be a direct bolt-on installation, or not.

Good news: there are hundreds of different options on the market – it won’t be hard to find the right fit for your four-wheeled friend. You will have to do some digging, however. At a local store, ask the staff members to help you out with the choice. At an online store, refer to a compatibility chart: it will help you make an educated decision.

The Intake Tube

Best Cold Air Intake for Jeep Liberty When it comes to the tube’s design, it should be aerodynamic and mandrel-bent. That’s pretty much all you need to know about the tube. It’s the most important part of any cold air intake kit; so, depending on how good of a job the engineers did, the improvements can be pretty great. Mostly, I’m talking about gaining extra HP/torque, of course. This gear is also capable of changing the way the engine sounds.

The factory cooling system is quite restrictive and doesn’t really sound like much. That’s because it’s simply not as powerful to make the vehicle roar. Secondly, many manufacturers deliberately make it mild and smooth so that the drivers and passengers are comfortable. But, since we’re here talking about air kits for off-roading, the louder and meaner its tone, the better!

What’s the Deal with Filters?

Best Cold Air Intake for Jeep Liberty Along with the intake tube, the filter plays a key role in protecting the engine. However, instead of battling extreme temperatures, the filter safeguards the motor from contaminants. Those include debris (tiny rocks and pieces of wood on the road), dust, pollen, and more. With filters, you have a choice between dry and oiled units. So, what’s the difference between the two? Which one should you pick?

Dry filters are cheaper. Plus, they don’t have any negative effects on performance. However, once they get clogged, the only thing you can do is buy a new one. Some experts recommend blowing the dust away, but that doesn’t usually fix anything. On average, OEM dry filters last for 15-20K miles, depending on the area that you live in, the engine, and how well you take care of it. That might seem like a decent lifespan, but not when you compare it to oiled filters.

A cheap oiled filter can easily go on for twice as long. A proper one, in turn, serves for up to 60-70K miles, or even more. For example, the K&N filters only require cleaning every 100K miles. And, they don’t take much time or effort to clean. If you’ve got a hose and some soap, you’ll be done in no time. Oiled filters are more expensive, though; plus, because of their design, they do slow down performance by 1-2%.

Efficiency – what to look for?

As we already learned, the #1 job of any aftermarket cold air intake system is to improve the air filtration and flow. That way, it can keep the engine from overheating. The best (and most expensive) intake tubes boost the airflow by up to 50%, which makes a dramatic difference compared to the stock gear. Most companies “dyno-test” their air kits to ensure efficiency in real-world applications. So, if you see that in the specs, rest assured it will be a good purchase.

Best Cold Air Intake for Jeep Liberty

Even if the increase in airflow is 20-30%, it will be more than worth paying for. Moving on to the performance side of things, don’t expect any life-changing improvements. On average, you get 5-10 extra HP and torque. In other cases, the boost will be 5-10%, which is roughly the same. Now, if you’re driving a Wrangler, the powertrain will get a bigger “kick” out of a new air intake, but the Liberty isn’t as lucky in this regard.

I do, however, want to add that with a new intake kit, it’s very well possible to make the Liberty accelerate faster, climb steep hills easier, and even be more fuel-efficient.

Conclusion

Did you know that the Liberty was positioned by Jeep as the official replacement for the Cherokee? That’s right: it filled the gap between the legendary Wrangler and the bigger, stronger Grand Cherokee. Sadly, it was discontinued in 2012, but, if you invest in a premium-quality cold air intake system, the Liberty will turn into one hell of an off-roading champ. For today’s list, I hand-picked four air kits and vouch for every single one.

They’re not identical to each other, however: some are cheaper, while others are slightly on the expensive side. Their pros and cons differ as well. That’s why I want you to give each intake system the attention it deserves and read my reviews thoroughly. A decent intake tube and filter last for many years; so, make sure you’re happy with your pick!
