The K&N FIPK cold air intake for 2004–2005 Ford F-150 4.6L V8 uses a roto-molded HDPE tube to increase airflow and is paired with a washable, reusable high-flow oiled cotton filter. K&N guarantees an increase in horsepower and torque and rates long service intervals—up to 100,000 miles between filter services under normal highway driving. A custom heat shield protects intake air; typical install time is under 90 minutes.
