    The K&N 57 Series FIPK Performance Air Intake System (part 57-2525-2) is a high-flow cold air intake for the Ford Super Duty 5.4L V8. A high-density polyethylene (HDPE) rotationally-molded tube increases the volume of airflow to the engine and is paired with a washable, reusable K&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. K&N lists this kit as not legal for sale or use in California on any pollution-controlled motor vehicle; some specific models and years may be legal in CA, so check the CARB status for your vehicle in the K&N application listing.
