The K&N 57-2541 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 57-2541 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 past the mass air sensor and 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, air bypass valve, air temperature sensor and crank case vent hose. The oversized conical 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. The only tools needed are a screwdriver, ratchet set and several wrenches in most cases. 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


  The product is great and the service was fast couldn't be more pleased. Can not believe the increase in power. The product was easy to install except for the 5/8'' hose was real tight and took much effort to get on. Very happy with product and K&N.

  I just ordered my kit for my 03 Ford supercrew. I don't need to have it to review it. I have a k&n filter, outerwear, and oil filter on my ds650, oil filter and fuel filter on my ford, intake, outerwear, fuel and oil filter on my dodge Cummins 2500, and air filter, outerwear and oil filter on my crf450. K&N makes the best products available. I have been in the automotive sevice industry for 20 years and own a service shop. I recommend all of their products to every customer because they work. There is no substitute...There are alot of cheap imitations but nothing comes close to K&N, I guarantee it to everyone that's comes through my doors.

  I have a 1997 Ford F150. I don't know why I waited so long. It's the best thing for my truck.

  I like what the intake kit did for my Expedition, I was getting 13.4 MPG now I am getting 14.7. I found a 1.4 MPG increase in mileage and I am grateful for that. The response is so much quicker and of course the sound is really cool!!!! Then I also put on a set of shorty headers and increased my mileage by 1.3 MPG that's a total of 2.7 MPG with a grand total of 16 miles per gallon. At this moment in time my mileage is still increasing the other day I hit 17.2 miles to the gallon, and I have a 5.4L. After my future trip I would like to report back my gas mileage, at this rate, I'm sure its going to be great!! Thank you K&N. A very happy customer.

  My restored 1999 Ford Expedition has more power and better response during acceleration. Prior to installing the K&N intake, I installed a performance exhaust system and experienced a moderate amount of HP increase. After I added the K&N intake it turned my late model SUV in to a beast. This truck has never performed so good. I recommend this product to anyone looking to improve the performance of their vehicle at an affordable price.
