K&N is the world-wide standard in high-end quality performance air filtering systems. Made from multiple layers of pre-oiled woven cotton gauze material that is mesh screen protected. They are washable and can be used as stock replacement.

K&N filters decrease service intervals; are better flame resistant and will last much longer than comparable foam or paper type filters.
