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.

I didnt think it would make that much of a difference. My 02 Ford F150 4.6 has been having issues with power and it was dogging out on me. I went for a drive after i installed it and WOW It sounds so mean and the power is unbelievable. I wasnt expecting that much of an increase. Ill have to drive it more to see if the problems went away. I struggle up the same hill every day on the way home from work when i just took it out i accelerated faster up the hill than i did before on flat ground i fell in love with my truck all over again. Thank you K&N you guys are amazing I am forever grateful i am going to tell everyone i know about your product.

Love this air intake, it improved gas Mileage and a lil bit of horse power. The only thing I don't like is that it comes with a plastic intake tube.

Excellent product overall increase in mpg + 3 . Loads more torque. Put some windburn the old girls sails. Just wish packaging included a larger sticker.

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.
