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.

I have been driving my 2013 Ford Transit Connect for a couple of months. I have purchased KN filters for all of my previous vehicles. The filter in my Vuck ( best description of a van and a truck) has increaincreased the power in my Vuck. ..and only slightly in the mileage category. I find it important to be able to pass someone on a 2 lane and this filter did it all. If you have a Vuck I strongly recommend it.

I love this air filter, the way it makes my 2014 Ford Focus ST sound and perform is amazing. Can't thank my amazing girlfriend enough for getting me this, this past Father's Day. Awesome product.

After straight piping and the K&N filter in my '05 Ford dually, I feel like a kid again. (can't tell if I'm getting better mileage cuz I can't seem to keep my foot out of it!)
