Filters out harmful contaminants. The K&N Air Filter filter's out harmful contaminants with it's 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.
Direct Fit Replacement. K&N designed this Air filter to be a direct fit replacement for the 2008-2009 Bullitt Mustangs with the factory cold air intake.
