Product Description

An air filter is an important part of a car's intake system, because it is what allows the car to "breathe." An engine needs an exact mixture of fuel and air in order to run, and all of the air enters the system first through the air filter. This catches the dirt and other foreign particles in the air, preventing them from entering the system and possibly damaging the engine.
Car air filters are generally pretty cheap, due to the filter's simple construction. Most are paper-like or fibrous material, folded accordion-style and arranged on a plastic or metal frame. Some are made out of a cotton or fabric-like material, which is then oiled in order to increase airflow. Vehicles generally have a specific holder for this filter, which is usually a plastic or metal box. Generally, the holder is connected to the intake manifold by a large plastic tube through which the air flows.
