2006 Ford F-150 4.6L cold air intake by K&N 57-2569 Air Charger. The K&N Air Charger F-150 4.6L cold air intake provides a 8.48 horsepower gain with better fuel efficiency. Easy to install with simple hand tools. Features the famous washable and reuseable K&N cotton gauze high flow air filter. Specially designed air tube smooths and straightens the airflow and insulates the air/fuel mixture from heat. Includes detailed installation instructions and all hardware required to install.
Provides a dramatic improvement over a K&N O/E replacement filter alone. This intake uses only non-metallic rotationally molded tubes that can reduce air temperature and decrease intake sound over a metal tube. Restriction can exist BETWEEN an air filter and the engine reducing the benefit of a K&N Air Filter. The weakest link in the airflow “chain” robs a vehicle of its natural horsepower. Often that weak point is the factory air path leading to the Engine. K&N Air Intake Kits virtually eliminate air path restriction by replacing the air filter and the entire air path to the engine. The aerodynamically engineered tube drives a massive amount of air into an engine, which translates into POWER.
