Ford recommends you replace your engine air filter every 30,000 miles. It's really easy to do, and should only take a few minutes.

Note: The owner's manual states that the correct air filter is the Motorcraft FA-1914. However, at least one printing of the Fiesta ST supplement recommends the FL-1908, which is not correct. If you are still unsure, put your VIN into the Ford Parts Website and click through to Air and Fuel Delivery->Filters to find the right model number.
