K&N Performance Intake Kit for Ford C-Max/Focus II – Extreme Performance & Offroad
K&N 57i Generation II Induction Kits are built primarily for European vehicles. These intake 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. The weakest link in the airflow chain robs a vehicle of its natural horsepower.
