The K&N roto-molded cold air intake for 2001–2005 Honda Civic L4-1.7L increases airflow with a high-density polyethylene (HDPE) tube and includes a washable, reusable high-flow oiled cotton filter. The oversized conical filter can extend service intervals up to 100,000 miles under normal highway driving. A custom heat shield helps protect intake air and the system is typically installed in under an hour; K&N backs it with a lifetime limited warranty and notes to check CARB status for California.
