Best Air Filter for Jeep Wrangler (Review & Buying Guide)

If you’ve never given much thought to your Jeep’s air filter, you’re not alone. Many people simply use their jeep to get from one place to another and enjoy off-roading.

But after prolonged driving, you will begin to notice a difference in air quality. You may see thick air, reduced airflow, a dirty odor and weird colors in the air.

Just like the air filter under the hood of your jeep that allows your engine to breath clean air, your jeeps interior heating and air conditioning system also has an air filter allowing you and your passengers to breath clean air.

The factory filter is a large one-piece paper style filter that can be pretty flimsy and some models of the Jeep Wrangler don’t come with even that.

So if you’re on the lookout for new air filters for your jeep wrangler, you’ve come to the right place.

Here is my list of the top 5 options that you can find online:

aFe 31-10155 Magnum Flow OER Pro DRY S Air Filter for Jeep Wrangler JK V6-3.8/3.6L

PROS

  • Durable as this filter can last for years
  • As this is a dry-filter, there is no spillage of oil or mess involved
  • The thick rubber seal around the filter ensures that no dust or moisture gets in

CONS

  • Issues are mostly due to improper fit so aFe should come up with a list of jeep wranglers this model is compatible with

The aFe Magnum Flow air filter has been created to suit Jeep Wrangler JKs. Made of plastic, this filter features 3-layers of synthetic polyurethane to keep the engine running well.

These layers let airflow even when it is quite dirty. The filters use a rounded pleat design to increase the surface area thus increasing the dirt/dust capturing capacity.

Since this is a dry filter, it is easy to clean. There is no oil involved in using this filter thus it can be used multiple times after cleaning it- which is something oil-filters cannot offer.

Cleaning them is as easy as stacking them on a flat surface but we recommend using a vacuum cleaner/hose to do the job.

The filter is sealed with urethane which ensures minimal leakage and eliminates the usage of gaskets or sealants. Since the urethane is soft, it will return to its original shape allowing for a better fit.

The synthetic materials used make it weather-resistant so if you plan to use your jeep wrangler in hot weather, the aFe is a good option.

aFe claims that we can see an improvement by up to 45% in horsepower and torque, now we cannot measure that exactly but we did see better performance and quieter idling time.

All aFe filters come with a lifetime warranty. Many owners have had these for an extremely long amount of time, 5 years and up.

  • Easy to install but you can get a professional to do so at a cheap cost

The pleats on this filter rise in both directions around an inch from the center, increasing the surface area. you’ll save money compared to anything out there.

Some reviews even mention using this filter in the desert. It almost looks like an OEM swap to us but is cheaper and the quality cannot match the former.

It’s a thinner design with the sealing plastic being softer than the OEM. Installation is pretty easy and all you need to do is drop the glove box open, pinch in the tabs on the side to swing it further, remove the old filters and drop the Fram filter ones.

Fram recommends that you replace these filters on reaching 12,000 miles as this point further you will not see an improvement in performance.

Guide to Buying An Air Filter

Here are a few features that determine how well the air-filter works and will help you choose the right one for yourself:

Compatibility:

You should check for the specifications of your car model before shopping for a new one.

An easy way is to look at the part number and specifications in your old filter and buy one with the same numbers.

Otherwise, when you buy online, you can a compatibility list to cross-check your jeep with the air filter

Types of air filter:

Paper Engine Air Filters

The most rudimentary kind of air filter, they are made of paper using a special kind of wood pulp.

K&N High-Performance Filter Jeep Wrangler JK

Being fine and porous, they are pleated out to increase the volume covered. It usually weighs between cover 100 g/m square to 200 g/m square in weight.

These filters are sealed with foam or plastic at the edge. They are affordable compared to other types and are good for jeeps present in less dusty areas or less pollution. However, they tend to get worn out after reaching a particular mileage and cannot be reused.

Cotton Engine Air Filters

This air filter has multiple rows of cotton trapped between mesh screens. The cotton material is dipped in oil which helps trap most of the dust without affecting airflow.

They are long-lasting and reusable. When you feel that the filter is clogged, you can wash and re-oil it. But if you’re the no-fuss involved kind of person, you will find the maintenance to be annoying. Also, they tend to be more expensive than paper filters.

Foam Engine Air Filters

These are very similar to cotton filters but they use polyurethane foam instead of cotton gauze. It is also dipped in oil to trap small dirt and dust particles from the air.

They are reasonably priced and are the popular choice for off-road vehicles as they can tackle a lot of dust and dirt.

Temperature Resistance:

If you live in an area that experiences high-temperatures, you better chose air filter which is resistant to extreme weather.

Ease of Installation

Instructions that are simple and easy to follow are always a bonus feature, especially if you are a beginner. For some filters to operate properly, a particular side needs to be towards the air source.

You can get professional auto mechanics to do this for you and usually they should charge around $ depending on your jeep model.

But the service charge will end up being pricier than your air filter! Youtube is a good resource and you can refer them to install most of the above filters.

Lifespan

The lifespan of air filters is measured in terms of miles or months. It is quite obvious that the lengthier the lifespan of the air filter the more value for money you get.

K&N High-Performance Filter Jeep Wrangler JK

This also means they will have to be replaced less frequently. Even if the filter is easy to clean, you wouldn’t want to keep taking it out and cleaning it.

Final Thoughts

All manufacturers mention the lifespan on their box and you shouldn’t try to use it beyond the set lifespan. At that point, they could be really dirty and will not adequately protect you from dirt and dust which is bad if you suffer from allergies.
