The K&N 57-2524-2 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 57-2524-2 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 through an aerodynamically engineered intake tube into the engine’s throttle body for a guaranteed power gain. The tube accommodates the factory mass air sensors, air temperature sensor and PCV lines. The oversized cone shaped 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.

K&N 57-2524-2 Air Intake Product Reviews

Thursday, April 6, 2017 - Part 57-2524-2
Installed on my 1999 F250 6.8L V10 2 Wheel Drive with 4.3 limited slip rear end. Easy installation with detailed instructions. I was already impressed with the V10, but I can notice the difference with the K&N air intake. The heat shield keeps the air filter nice and cool. Looks and sounds great.

Easy install. Done in less than a hour. Instructions were well written and easy to follow. I noticed an immediate increase in throttle response. I should have done it a long time ago. DJ.

It shipped very fast and came in a huge box with contents in tack. Very good instructions and for those of you that like pictures, it even has them. I found them valuable because like most instructions, they are vague so the pics. help. I can't say it increased my gas milage, but it did give it more power when starting off from a stop light or when overtaking and passing another vehicle. Good product, easy install and no modifications needed. Fit like OEM product.
