Description K&N 57-2525-2 Performance Air Intake System FORD F-SERIES SUPER DUTY, V8-5.4L; 1999-04

A high-density polyethylene (HDPE) rotationally-molded tube increases the volume of airflow to the engine and provides a guaranteed increase in horsepower and torque. This system is paired with a washable, reusable High-Flow Air Filter featuring oiled cotton filter media.

The oversized, conical air filter design allows up to 100,000 miles between filter services under normal highway driving conditions. A custom heat shield helps protect intake air from engine bay heat, and installation can typically be completed in less than 60 minutes.
