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

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

My wife was complaining about a musty smell for the last three years every time she turned on the air conditioner. I checked my owners manual for the 2011 Ford Explorer and no cabin filter was listed for that year. My Explorer was one of the first ordered and shipped to St. Louis. After talking to some of my friends at Ford, I came to find out that since my car was one of the first produced, they discovered that they failed to list the cabin filter in the manual, that being fixed on all later models. Once I discovered the error, I went to K&N to look up the replacement. She's hasn't had much chance to use the air conditioner yet but the fact she's no longer complaining convinces me that your product is working. I've been using K&N air filters for the past 15 to 20 years, love the product, and I'm sure the cabin filter will perform as well. David
