K&N Factory Tour - Panel Air Filters
Panel air filter production begins with research and testing of original equipment filters both in and out of the stock air box. Manufacturing of panel filters utilizes precision injection molding techniques using aluminum molds that are engineered and fabricated on-site at K&N. New production techniques and materials are constantly being tested as technologies change and air box construction evolves. Applications are updated year-round to stay up to date with new automotive releases and to confirm fitment and performance.
