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 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!)

THE ABOVE PART NUMBER MATCHES THE AIR FILTER I BOUGHT FOR MY 2012 F-150 FORD PICK UP. THE REASON I PURCHASED THE AIR FILTER WAS TO HOPEFULLY GET MORE MILES PER GALLON FUEL ECONOMY AND MAYBE A LITTLE MORE HORSE POWER. THIS WOULD BE VERY HELPFUL WHEN WE ARE PULLING OUR RV. RECENTLY WE TOOK THE RV TO MICHIGAN AND I REALLY DID NOT NOTICE ANY BETTER MPG OR POWER. I REALIZE IT MAY BE DIFFICULT TO NOTICE ANY IMPROVEMENT WHEN TOWING AN EXTRA 5000 LBS. I DO FEEL THAT THE AIR FILTER MAY PROVE TO HELP MPG AND POWER WHEN NOT TOWING-TIME WILL TELL! I ALSO PURCHASED A K&N AIR FILTER FOR MY 2013 HARLEY SOFT TAIL. THAT FILTER DOES SEEM TO PROVIDE BETTER REPONSE (ACCELERATION). I HAVE NOT CHECKED MY MPG VERY CLOSELY TO SEE IF THAT HAS IMPROVED. BOTH AIR FILTERS FIT VERY WELL AND WERE EASY TO INSTALL!
