K&N 57 Series Performance Air Intake System for Select 2005-2006 Ford F-250/F-350 and Excursion (V8-5.4L)

Fits 2005-2006 Ford Excursion, F-250 Super Duty, and F-350 Super Duty (V8-5.4L).

The K&N 57 Series Performance Air Intake System (FIPK) replaces the restrictive factory air filter and intake housing to improve engine efficiency and power. This kit features a rotationally-molded high-density polyethylene (HDPE) tube designed to increase the volume of airflow while smoothing the intake path to your 5.4L V8 engine. By reducing air turbulence and isolating the intake from engine bay heat with a custom heat shield, this system provides a consistent increase in horsepower and torque.

This intake is equipped with an oversized, conical K&N High-Flow Air Filter featuring oiled cotton filter media. Designed for longevity and performance, the filter is washable and reusable, requiring service only every 100,000 miles under normal highway driving conditions. The entire system is engineered for a precise fit and can typically be installed in less than 90 minutes using standard hand tools.
