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


I recently experienced a failure in a component of my 57-2541 Cold Air Kit after 100,000 trouble free, fuel saving miles. The problem was easily diagnosed and repaired by me at home. I contacted Elzabeth Taylor in Customer Service who was extremely helpful and very understanding in regards to my situation. She instantly shipped me a the part to replace the part that I field fixed in my driveway. She requested that I take some photos and send them to her so that Research and Developement could take a look and make any adjustments if necessary. I was delighted to comply and sent them back to her later that evening. I have K&N Cold Air Kits in my 1999 Ford F-150 and my son's 2013 Chevy Sonic 1.4 Turbo. I have an air filter in my wife's 2012 Dodge Caravan. Your products have served us well and delivered the performance figures that you quoted. Actually, I got better than quoted performance on my 1999 F-150. I averaged over 1.5 mpg increase after the intallation. I will be purchasing a Chevy Silverado with a Duramax Diesel engine very soon. I am anxious to see what we can do with K&N products at that time. Keep up the good work and the great customer focused service.

I bought both of these items for '87 Ford Windstar gl v6 3.8l vehicle they both good products and this is what I always buy from now on. Thanks for K&N products.

I went from a Fram Tough Guard air filter to this thinking it would improve my overall horsepower and MPG and boy has it ever! Within the first month my hp has increased by at least 5hp and I'm getting almost 18 mpg! Which is fairly decent for a 5.0 v8 engine. I would recommend this filter to those wanting to get the most out of their ford 1995 F150 pickup!
