The air cleaner assembly in your luxury car or SUV consists of the engine air filter and a housing. If you're driving an older model, it can be found above or next to the carburetor. In newer vehicles, it's above or beside the throttle body. What it does is simple. It helps to prevent airborne contaminants from getting into the engine, building up, and inhibiting airflow.
Modern air cleaner assembly housings are usually made from either metal or plastic. They have removable lids that make it easier to access the air filter. The air cleaner assembly itself can be one of several types.
Pleated paper air filter assemblies are most common. They're ideal for everyday driving, easy to replace, and affordable. Sports cars and performance vehicles may feature foam or cotton air cleaner assemblies. Both deliver optimal airflow and are capable of retaining large amounts of dirt. Finally, oil bath air cleaner assemblies are best for off-roading, due to their high air filtration nature. They feature sumps that contain pools of oil, along with an insert made of fiber, mesh, or foam.
