The 57 Series Generation II air intake, also referred to as an FIPK^®, is K&N's ultimate performance product. These performance intakes are designed to increase power by as much as 10%. 57 Series FIPK's are CARB exempt, street legal in all 50 US states, come with a Million Mile Limited Warranty and are guaranteed to increase power. K&N air intake systems replace your vehicle's restrictive factory air filter and air intake housing. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This translates into more power and torque for your vehicle. The filters on these kits are washable and reusable. Most of our air intake systems are relatively easy to install using tools commonly available (see installation instructions). [MORE]

Product Reviews Review part 57-2525-2

I bought a 2000 Ford F-250 with the 5.4l Triton and with 183,000 miles I changed my oil with Royal Purple 5w20 and of course, the K&N oil filter. When I initially bought the truck it had the cheap "brand removed" filter and some cheap, low end oil. It ran fine, but after installing the filter and using the Royal Purple oil it's running really smooth, next month I'll be adding the K&N FIPK 57 Series air intake for it. My dad also has a 2005 Ford F-250 with the 6.0l Diesel and he has the K&N air intake as well, we're both very impressed, great job!

K&N Filter Believer!

I just purchased a 2003 F-250 Super Duty with a 5.4 engine only to find out it got 9 MPG.!!! We use the truck for service adding up lots of miles per month. After reading about your air filter and grumbling about the price I purchased one... Boy are we saving at the pump now!!! 13 MPG! Doesn't seem like a lot to your around town drivers but this truck gets the oil changed every 6 weeks (yes every 3000 miles). Add it up, at the end of the year we saved a lot more than that filter cost. Thank you! Your product is great... but now could you do something about my Motherinlaw?

FIPK2 Testimonial
2004 Ford Excursion, small V-8 - 5.4 liter. This thing was a dog until I put the kit on. Will never go back. Runs smoother, better mileage and the A/C is colder?

Product is better than advertised so good, I just ordered another FIPK for my 2nd V-8.
