K&N crankcase vent filters were designed for racing, but they're nice enough for show cars. They come in several styles, with universal mounting abilities to fit a wide variety of valve covers. Some styles also have shields for extra protection. The top plates and shields are chrome plated for beauty and durability, and some inlet tubes are zinc plated. The reliable filter elements are reusable, washable, and come pre-oiled, ready for use. They can be covered by up to 1/4 in. of debris before airflow restriction makes cleaning them necessary.
