The K&N 57-2543 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 57-2543 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 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 and requires commonly available tools. 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 can't compliment the kit more than the performance does. The kit brought new life to a 20 year old engine. The ease of assembly made it even more enjoyable. Thanks for a great product. Mike '96 Ford Bronco

Absolutely the BEST item I have ever purchased for my truck. K&N engineering is genius. My truck runs 150 percent better than it ever has. It was an INSTANT difference the second I started my truck. Thank you for giving new life to a 19yr old truck

I am very happy with this intake kit. It was very easy to install with the minimal tools I have. The instructions were very straight forward and simple. It has noticeably changed the horse power, and more so, torque of my Ford pickup! I would also add that if someone is looking for an intake that doesn't add a bunch of engine noise, like some on the market, K&N is the best choice! Thanks K&N. Keep up the good work.
