The K&N 57 Series FIPK 57-2556 air intake system replaces 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 allows your engine to inhale a larger amount of air than the factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The 57-2556 air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the previous air box space. Air is directed through an aerodynamically engineered intake tube into the engine’s throttle body for a guaranteed power gain. The oversized air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install usually in 90 minutes or less using commonly available tools. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.

Product Reviews

  We installed the 57-series intake on my 20606 For F-150 and it took us about 90 minutes; the results were awesome. We took it for a test drive and when I hit second gear it spun the big 35's and sounded mean with the stock exhaust , I couldn't be happier.

Larry Love Everett, Washington
  The parts fit perfectly. It took a little longer to install than I expected, but that's on me. I took it slow and did it right. I am very happy with the results.
Tony Flock Washington
  My only complaint was that it took two days to process before it was shipped out otherwise it arrived when it was supposed to. It was a breeze to install in my truck. Definitely sounds better. I haven't used it enough yet to see if I'm getting better mileage or not.

  This is the biggest difference I have made in any engine in the shortest amount of time with a simple bolt on product.
