The K&N FIPK 57-2575 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 57-2575 air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the lower air box. 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 sensor. 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. The tools needed are a screwdriver, a ratchet set and several wrench. 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!! Put it on my 2010 4x4 F-150 5.4L. Gave it great sound!! Quicker acceleration and an increase of 3.5 MPG at 60 MPH. Very pleased!!
Robert Barton, Whiteville, North Carolina
 Everything fit well and went together easily. My truck seems to answer the throttle more eagerly. I haven't driven the truck very far since installation however, I seem to be getting a slight increase in mileage. I'm happy with the system.
Alan Griffith, Mission Viejo, California
  Good product, quick, easy install. It took about 35 min. to install. All needed parts (nuts, bolts, washers, clamps) were included. There is more noise from the intake system, but not at all objectionable. Get one, you'll like it.
