This 57i Generation II Induction Kit (Ref. 57S-9508) from K&N uses only non-metallic rotationally moulded tubes which help to 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.
The weakest link in the airflow chain robs a vehicle of its natural horsepower and often that weak point is the factory air path leading to the engine. These 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 huge amount of air into the engine, which translates into power.
Please note 57i Intakes are not legal for use in California and other US States adopting California emission standards.
