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 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.

Still too early to judge the intake system. I will say the truck responses quicker then before. Not sure about gas mileage or real horse power yet.

My old 2002 F150 with 150k miles on it, loves it! As the truck gets older, it could use all the help it can get. With this new cold air, my truck runs like it should. Awesome product.

The buy was easy and fast shipping. As filter is a great product, I've been a big fan of K&N for many years, so I thought why not to upgrade my 2000 F150,5.4 liter engine and give it what it should have. The installation took almost 2 hours, wasn't neither easy but neither to complicated, just used basic garage tools. And here I am, my truck now pulls nicely and I can feel a big difference from the original filter. Thanks again K&N, will see you soon to upgrade my other vehicles.

This intake is great only reason I give it 4 stars and not 5 is that when I received the package I was missing some of the hardware to install it and had to run to Home Depot and grab a few washers and bolts but this intake definitely does what it says increased hp noticably, I've always used K&N on all my cars and that won't change best aftermarket cold air intake made.

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.
