K&N Fuel Injection Performance Kit 2002-05 Envoy, TrailBlazer, and Oldsmobile Bravada 4.2L

The World's Best Flowing, Best Filtering High-Performance ''Street-Legal'' Air Filtration Systems

These 57 Series Gen II Air Intake Kits (FIPKs) are built for many different vehicles and represent a dramatic improvement over a K&N OE 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.
