This automotive maintenance tutorial was specifically written to assist owners of the updated fifth generation (2010, 2011, 2012, 2013 & 2014) Ford Mustang in cleaning or changing the engine air filter element for the Coyote 5.0L V8 motor..

Owners of the earlier 5th generation Mustang from 2005 to 2009 and possibly the 4th generation 1994 to 2004 models with similar engine air boxes may also find these DIY instructions to be helpful.

A few compatible replacement filters with their part numbers are as follows: Motorcraft FA-1897, Fram CA10781, Mann MA 1247, Purolator A35907, Champion CAP10781, AEM 28-20431, Ecogard XA5907, K&N 33-2431 and Hastings AF1487.

No tools are needed to change the air filter. A wet/dry shop vacuum can be useful for cleaning the air box and the existing filter.

Inspect Both Sides
The engine air box is located on the right (driver) side of the engine bay in between the suspension tower and the fuse box.

Flip the two metal latches on the right side of the air box down to release them.

Lift the top half of the air box to reveal the old air filter.

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

Clean Old OEM Filter

Install New Air Filter
Inspect both sides of the existing air filter.

If the old filter is relatively clean, just tap out the large debris and remove any fine dust with the wet/dry shop vacuum.

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

I always buy the OEM Ford Motorcraft FA-1897 engine air filter since it has excellent reviews on Amazon.

If you prefer to have a re-usable filter, go with the K&N 33-2431 which will need to be washed and re-oiled every 50,000 miles.

Insert the new filter in to the lower half of the air box with the pleats facing down and the metal screen mesh facing up.

Slide the slots on the right side of the top half of the air box over the tabs on the lower half.

Flip up the two metal latches over the top half of the air box to secure it in place.

Make sure that the halves of the air box are flush together with no parts of the air filter visible.
