K&N RF-1047 composite-top universal air filter features an oiled cotton media and a carbon fiber–style top for lightweight strength and a smooth finish. It clamps on with a 3‑inch inside flange diameter and a 1.75‑inch flange length, with a 6‑inch base diameter and 5‑inch top diameter. The filter is washable and reusable, with pliable flanges to absorb vibration and allow a slight stretch to fit between sizes.
