OVERVIEW K&N 57i Generation II Induction Kits 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 alone. 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. Estimated Horsepower Gain*: 11 HP @ 4200 RPM DETAILS Guaranteed to increase horsepower Designed to improve throttle response and engine sound Replaces entire factory air intake system Aerodynamically engineered tube drives more air into the engine, resulting in MORE POWER. Eliminates air path restriction by replacing the air filter and the entire air path to the engine.
