K&N 57 Series FIPK Air Intake Kits represent a dramatic performance improvement over a K&N O/E replacement filter alone; they use only non-metallic rotationally molded intake tubes that can reduce air temperature and decrease sound over a metal tube. Air flow restriction can exist between the air filter and engine reducing the benefits of a K&N performance air filter. K&N air intake kits virtually eliminate restriction in the air path by replacing the filter and air path to the engine. The aerodynamically engineered intake tube drives a massive amount of air into an engine, which in turn adds power.
