The K&N 57-2546-1 FIPK 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 57-2546-1 air intake comes with a 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 tube accommodates the factory mass air sensor and air temperature sensor. The oversized oval shaped 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 the existing factory mounting points and requires 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


  Instruction book needs to be updated, as there were a few steps left out. And the nylon lock nuts should be updated to newer ones as the ones supplied were old and not pliable, but everything else fit and works fine. My truck has more low rpm pick up and power before. Thanks.
Parker Groves Lawrence, Kansas
  Installation was easy and straightforward; I like that this setup is open and let's the truck get more air. I can tell that the throttle response is quicker and the turbo spools quicker. A little more turbo noise in the cab but not very noticeable unless you are listening for it. In my opinion, I like to hear the turbo more anyway. I haven't got to drive it enough to see if the mpg has changed. I would recommend this kit to anyone wanting an air box upgrade. Fast shipping too.

  Started working on it late at night and finished up first thing in the morning. Used the paper instructions along with the online you tube video instructions and it was pretty easy to install. I noticed a big difference in the sound and performance of my F250 right away.

  Immediately noticed the power difference once the cold air intake was installed. Second cold air intake I purchased. My previous purchase was for my 2004 Trailblazer. Excellent results with that install and I am sure this one will be no different.

  I am satisfied with the new filter.I think my Turbo is functioning better.I have not been able to tell if I am getting better gas mileage or not yet.I do believe the truck has more power than it did prior to the installation of the new filter
