Lincoln Navigator Ram Air Intake

K&N Ram Air Intakes - K&N 57 Series Gen II Air Intake Kits (FIPK's) are built for many different vehicles and represent a dramatic improvement over a K&N O/E replacement filter alone; they use 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.
