Gain some extra horsepower while building your custom system through this K&N air cleaner assembly (66-3040). Since this 2-3/4” tall assembly stems from the X-Stream Airflow series, it’s designed with a top filtration area. It simultaneously guides air inside the red, cotton gauze filter element so it can draw in more air from the side pleats. Not only does this create spectacular performance efficiency, but it also means lasting operation since the element is washable and reusable.
