Filters out harmful contaminants. The K&N Drop-in Air Filter filters out harmful contaminants with its unique layered design. K&N Air Filters are made up of layers of specially treated cotton gauze that are sandwiched between two epoxy-coated aluminum wire screens for durability. K&N uses a specially formulated grade of oil to treat the cotton gauze layers which causes a tackiness throughout the cotton’s microscopic strands creating a powerful filtering media that ensures engine protection.
Drop-In Replacement. K&N designed this Air filter to be a direct drop-in replacement for the stock 96-04 GT/Cobra, 03-04 Mach 1 & 01 Bullitt Mustang's air box, with no cutting or trimming required.
