57S-4001 K&N Performance Air Intake System, 2011 - 2019 Ford Ranger 3.2L L5 Diesel

K&N 57i Generation II Induction Kits are built primarily for European vehicles. They come with K&N's No-Hassle Lifetime Limited Warranty�. 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. Often that weak point is the factory air path leading to the engine. 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.
