This automotive "how-to" guide was specifically written to assist owners of the second generation (2008, 2009, 2010, 2011, and 2012) Ford Escape SUV in cleaning or replacing the air filter element for the Duratec 25 2.5 liter inline four cylinder engine.

Owners of other Ford, Lincoln, Mercury or related Mazda vehicles such as the Fiesta, Focus, Fusion, Taurus, Mustang, Edge, Explorer, C-Max, Expedition, F-150, E-150, E-350 Wagon, Flex, Transit Connect, MKZ, MKX, MKS, MKT, Milan, Grand Marquis, Mariner, Mountaineer, Navigator, and Mazda Tribute may also find these DIY instructions to be helpful.

A few aftermarket air filter elements include the following with their part numbers: Purolator A35323, Beck Arnley 042-1650, Hastings AFC1354, Pentius PAB8997, Motorcraft FA1696, Mann MA1016, K&N 33-2187 & Fram CA8997.

No tools are needed to clean or replace the engine air filter. A wet/dry shop vacuum can be helpful for cleaning the air box.

Two Clasps Released
Pull Open Air Box
Slide Out Old Air Filter
The black plastic air box is located at the rear right corner of the engine bay, closest to the driver seat.

Access the old air filter element by first releasing the two silver metal clasps on the top of the air box by flipping them upwards.

Pull the two halves of the air box apart and slide out the old air filter straight up out of the box.

Inspect Other Side
Clean Out Air Box
Cleaning Old Filter


Inspect both side of the old engine air filter.

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

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