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.

K&N 57-2541 Air Intake Product Reviews

Friday, September 30, 2016 - Part 57-2541
The product provides a huge boost to performance on my truck. The only reason I gave it 4 stars is because it took me 3-4 hours to put everything together. It holds true to the write up given by K&N. I have already recommended it to other people even.

Excellent product, installed it four days ago and noticed the increase in horsepower immediately. Very simple to install too.

It was a fairly easy install. It replaced a (Brand Name) I had on the truck since 2002. Wanted one that had the box to isolate the filter from the warm air from engine. Seems like good quality. So far I'm happy with it.

I had an imitation K&N intake prior to this one, and I have to say there is nothing like the real deal. You can feel and hear the power this thing gives my F150.

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.
