K&N’s state-of-the-art filter features thousands of microscopic cotton fibers, and an innovative design of layered, oiled cotton media helps to capture dirt and shield your engine from contaminants. Each filter design is tested in an ISO 5011 laboratory to ensure excellent filtration efficiency for outstanding engine protection.
