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.
