K&N Cold Air Intake

K&N 57-2574 K&N 57 Series cold air intake kit.

Fits 2007-2008 Ford F-150 4.6L cold air intake.

K&N Aircharger cold air intakes are easy to install with simple hand tools.

This intake is shown in the picture above.

Provides a 9.88 horsepower gain with peak power at 4200 rpm.

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 intake 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.
