K&N Racing Cone Air Filters

These filters are designed for the popular Formula Atlantic and Super Vee style cars, used in racing today. The filters fit into the air scoops and allow plenty of fresh clean air to enter the engine, but keep the small stones, tire dust and other racetrack debris from demolishing the engine. There is a hole at the small end of the filter to allow debris to exit the air scoop. Used by top teams around the country. The filters were designed for the vehicles listed below, but can probably be adapted to a wide variety of applications.
