The combustion air filter prevents abrasive particulate matter from entering the engine's cylinders, where it would cause mechanical wear and oil contamination.

Most fuel injected vehicles use a pleated paper filter element in the form of a flat panel. This filter is usually placed inside a plastic box connected to the throttle body with ductwork. Older vehicles that use carburetors or throttle body fuel injection typically use a cylindrical air filter. Usually in a metal or plastic container which may incorporate ducting to provide cool and/or warm inlet air, and secured with a metal or plastic lid. The overall unit is called the air cleaner.

For most cars, air filter replacement intervals vary between 15,000 and 30,000 miles, depending on the driving conditions. If you regularly drive on unpaved roads, it should be changed more often. If you don’t drive a lot, the filter should be replaced at least every 3 years, as with age it becomes brittle. An old filter can tear, allowing dirt to enter the engine.
