K&N Cold Air Intake

K&N 57-3021-1 1999-2004 GMC Sierra and Chevrolet Silverado 5.3L 4.8L cold air intake.

Provides 9.11 horsepower gain at 5352 rpm.

The K&N 57 Series Gen II Air Intake Kits (FIPK's) 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.
