K&N 57i Generation II Induction Kits are built primarily for European vehicles. They come with K&N's Million Mile 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. 57i Intakes are not legal for use in California and other US States adopting California emission standards.

Customer Feedback

Great product! Fit perfect and works better than the stock air cleaner. I have a K&N air cleaner in my Ford diesel pick up and it works great.

Installed the cold air intake in my 2014 Ford Explorer Sport. Even with the turbo, the response is improved and the sound is awesome!

Excellent product. Received it in 1 day....FREE shipping. Easy install with easy to follow instructions. Sounds great and immidiate improvement in throttle response. I can't really feel the HP gain but definitely notice the torque gain. Highly recommend. IMPORTANT: You need a 3/4 inch drill bit if your sensor is the push in type. For some reason a Ford Fusion has 2 different types of sensors. I had my stock parts removed and had to get a buddy to run me out and get a drill bit. Other than that, 45 mins to install.
