K&N 57 Series Gen II Fuel Injection Performance Kits (FIPKs) are multi-vehicle compatible and an improved version of K&N O/E replacement filter alone. These Air Intake Kits utilize only non-metallic rotationally molded tubes that have a greater capacity to reduce air temperature and decrease intake sound over a metal tube. The factory air path leading to the engine can often prove to be a limitation in the airflow chain resulting in the loss of horsepower. However, with K&N Air Intake Kits, this limitation is effectively taken care of by replacement of air filter and the entire path to the engine. More power is achieved by driving excess amount of air into the engine through aerodynamically engineered tube drives.
