The K&N 57-2530 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 57-2530 air intake comes with a K&N high-flow air filter and a heat shield that installs into the previous air box space. The placement allows air to be directed through an aerodynamically engineered intake tube into the engine’s throttle body for a guaranteed power gain. The tube accommodates the factory air temperature sensor and air filter restriction gauge. 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 existing factory mounting points. The only tools needed are a screwdriver and several wrenches. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.

 Great product. Easy to install. Can tell a difference especially with a performance tuner.
Clay, Alabama
 Installed in May 2013 on a 2003 F250, 7.3L diesel and the first thing I noticed was the increased engine noise at highway speeds. The fuel mileage increased slightly, maybe. It's a major job to get the filter off and clean. After finally getting the filter off to clean it, I decided to put the stock filter back on. If you don't like the noise of a diesel truck with the stock filter you should stay away from this kit.

 Easy installation. Fuel increase was only .5 to 1 MPG with no real performance increase. 2001 Ford F250 4X4, stock 7.3L diesel. 6inch lift with 33 inch tires.
