The K&N 57-2525-2 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 57-2525-2 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, idle air control 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.

I installed the intake on my 2004 F250. Adverstisment was accurate in regards to time involved to install. Looks good, a little bit of tone change in engine. Hope to see HP and/or MPG gains.

Awesome product, fast and easy to install, just 30 mins,fits like a glove, better throttle response and improvement on fuel and my pocket book. Made my engine sound more throaty, deep sound, and you can hear it sucking air. Have had it for 3yrs and has made a difference, plus its easy to clean. Love this cold air kit. Highly recommended!!!!!

I installed this on my 2000 F250 (5.4L) and was impressed with the ease of installation and increased fuel mileage. I saw an increase of 2+ mpg on the freeway. Thanks K&N!

I put on an intake system on a 1999 F250 5.4. The instructions were easy to follow, all parts fit perfect. This truck is use to pull a 27 ft. Airstream so when we get back from Florida in Nov. I will comment on performance, but from test drives this truck runs great. What an excellent product.
