A high-density polyethylene (HDPE) rotationally-molded tube increases the volume of airflow to the engine and is paired with a washable, reusable K\u0026amp;N High-Flow Air Filter with oiled cotton media. The oversized conical filter can go up to 100,000 miles between services under normal highway driving, and a custom heat shield helps protect intake air from engine bay heat.
