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

Thursday, May 24, 2018 - Part 57-2541
The product is working good and was not hard to install, however the customer service was sub par. It took several days to get a reply and then did not try to win me back to apologies for inconvenience. Very disappointed.

The intake works great, install was a little difficult but I have noticed a deeper engine sound.

I installed the K&N system on a 2002 Ford F-150 with a 5.4 engine with approx. 200,000 miles. I don't often rate products but this far exceeded what I was expecting. I had expected a modest gain in power and response but got a significant improvement in both. Would have bought it a long time ago if I'd known. Kendall Clemons
