Mazda3 Engine Air Box
Release First Metal Latch
First Fastener Released
This automotive "how-to" guide was specifically written to assist owners of the second generation (2010, 2011, 2012 & 2013) Mazda Mazda3 in cleaning or changing the engine air filter element in the Skyactiv-G 2.0 liter inline four cylinder motor.

Owners of other Mazda vehicles such as the Mazda2, Mazda5, Mazda6, MX-5 Miata, Mazdaspeed3, CX-5, CX-7, CX-9, MPV, Tribute, RX-8, Axela, Demio, Verisa, Premacy, and Atenza may also find these DIY instructions to be helpful.

A few compatible replacement air filter elements with their part numbers are as follows: Ecogard XA6280, Purolator A44688, Wix 49247, Beck Arnley 042-1700, Mann MA 1113, Mahle LX 1688, ACDelco A3121C, Hastings # AF1256, Fram CA11259, K&N 33-2293,

No tools are needed to access the engine filter.

A wet/dry shop vacuum can be useful for cleaning the existing element.

Release 2nd Metal Latch
Lift Up Top Half of Box
Old Engine Air Filter
The air box is located at the front right area of the engine bay next to the fuse block cover.

The top half of the air box is held in place by two metal latches.

Release the two latches by flipping them down and away from the air box.

Lift up the top half of the air box and slide it to the right to disengage the two black plastic tabs from their slots on the left.

Inspect Old Filter Element
Clean With Vacuum
Vacuum Out Air Box


Pull the old engine air filter out of the bottom half of the air box.

If the old filter is relatively clean like the one pictured above, tap out any large debris and clean it with a vacuum.

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

I recommend buying the Ecogard XA6280 engine air filter since it has excellent reviews on Amazon.

Vacuum out any debris from the bottom of the air box.

Insert New Air Filter
Push Tabs In To Slots
Top Half of Box In Place
Insert the narrower end of the air filter back in to the lower half of the air box.

Lower the top half of the air box in to place.

Push the tabs on the top half of the air box in to the corresponding slots on the lower half.

Flip Up Metal Latch
Secure 2 Metal Fasteners
Engine Air Filter Replaced
Flip up the two metal latches and snap them in to place on the top half of the air box.

Make sure that the two halves of the air box are flush together all the way around with no part of the new air filter visible.
