3.7L V6 Engine Air Box

Release 2nd Fastener Latch
This automotive "how-to" guide was specifically written to assist owners of the 2nd generation 2008, 2009, 2010, 2011 & 2012 Jeep Liberty equipped with the Chrysler PowerTech 3.7L EKG V6 motor in cleaning or replacing the engine air filter element.

Owners of other Jeep, Dodge, Mitsubishi or Chrysler vehicles with the PowerTech 3.7 liter EKG engine such as the Grand Cherokee, Commander, Nitro, Ram 1500, Dakota, Durango, M80 and Raider may also find these DIY instructions to be helpful.

A few compatible replacement aftermarket engine air filters include the following with their part numbers: Fram CA10228, Purolator A35670, Wix 49933, Pentius PAB10228, ACDelco A3159C, Champion CAP10228 and K&N 33-2363.

No tools are needed to clean or replace the engine air filter.

A wet/dry shop vacuum may be useful for cleaning the filter.

Lift Off Top of Air Box
Remove Air Filter Element
Check Underside of Filter
To access the engine air filter, first locate the two metal latches on the right side of the engine air box situated at the front left (passenger) side of the engine bay.

Flip the bottom of the metal latches upwards to release them and lift off the top half of the air box.

Clean Out Lower Air Box
Insert New Air Filter
Insert Tabs Into Slots


Pull out the old engine air filter element and inspect the top and underside of it. If the filter isn't very dirty, tap out the large debris and clean it with vacuum.

If the filter is dark black and clogged with dirt, dust, insects, leaves and other debris, it should be replaced with a new element.

I recommend buying the Fram CA10228 engine air filter since it has excellent reviews on Amazon.

If you'd like to have a re-usable filter that will last the life time of the SUV, go with the K&N 33-2363 which will need to be cleaned and re-oiled every 50,000 miles.

Insert the cleaned or new air filter element into the bottom half of the engine air box with the pleats facing down.

Secure Metal Fastener
Lock 2nd Metal Clasp
Engine Air Filter Replaced
Lower the top half of the air box down over the bottom half while inserting the tabs on the left side into the corresponding slots.

Close the right (driver) side of the air box and flip down the two metal latches to secure the air box together. Make sure that the two halves of the air box are flush all the way around.
