2012 Equinox Air Box
Remove Four Screws
Four Torx T25 Screws
This automotive "how-to" guide was specifically written to assist owners of the second generation (2010, 2011, 2012, 2013, 2014, 2015 & 2016) GM Chevy Equinox in cleaning or changing the engine air filter element in the LFW 3.0L V6 motor.

Owners of other GM vehicles such as the Spark, Sonic, Cruze, Volt, Malibu, Impala, Camaro, Corvette, Traverse, Tahoe, Suburban, Colorado, Avalanche, Silverado, Verano, Encore, Regal, LaCrosse, Encore, Enclave, Canyon, Sierra, Terrain, Acadia, Yukon, Savana, ATS, XTS, CTS, SRX and Escalade may also find these DIY instructions to be helpful.

A few compatible aftermarket filters include the following with their part numbers: ACDelco A3138C, Ecogard XA6131, Purolator A36131, Wix 49727, Fram CA10465, Hastings AF1430, Pentius PAB10465, Valvoline VA-255, Champion CAP10465 and K&N 33-2439.

The only tool needed to access and change the engine air filter is a Torx T25 star bit screwdriver.

A wet/dry shop vacuum can be useful for cleaning the existing filter or the lower half of the air box.

Lift Off Top Half
Engine Filter Exposed
Pull Out Old Filter
The air box is located at the front left (passenger) side of the engine bay.

Remove the four screws holding the top half of the air box in place with the Torx T-25 star bit screwdriver by turning them counter clockwise. Set them aside in a safe place.

Inspect Underside of Filter
Vacuum Out Air Box
Install New Filter


Lift the old air filter element straight out of the lower half of the air box and inspect both sides.

If the old filter looks relatively clean, just tap out the large debris and clean out any dust with a wet/dry shop vacuum before re-installing it.

If the old filter is dark grey or black and clogged with dust, dirt, hair, leaves, and insects, it should be replaced with a new element.

I recommend buying the OEM GM ACDelco A3138C engine air filter since it has excellent reviews on Amazon.

If you'd prefer to have a re-usable filter, go with the K&N 33-2439 which will need to be washed and re-oiled every 50,000 miles.

Replace Air Box Cover
Tighten Four Screws
Engine Air Filter Replaced
Install the cleaned or new air filter back in to the lower half of the air box and replace the cover. Insert the four screws and tighten them with the Torx T25 screwdriver.
