    Improve Your Horsepower and Torque. Release the hidden horsepower in your F-150 by allowing your 5.4L engine to inhale more air with the use of a Series 57 FIPK Cold Air Intake. K&N's Fuel Injection Performance Kit (FIPK for short) completely replaces the restrictive paper air filter and air intake housing with a smooth black intake tube and a red high-flow air filter. With the unrestrictive flow of air going into your motor, you'll have more usable horsepower, torque and acceleration throughout the entire RPM range, which will be beneficially when you need more power to haul a heavy load up a hill. Gains of 15.46 HP @ 3829 rpm and 21.21 ft./lb. of TQ @ 3829 rpm has been seen on a stock 5.4L F-150.

    Filters Out Harmful Contaminants. The supplied K&N Filter successfully filter's out harmful contaminants with it's unique layered design. K&N Air Filters are made up of layers of specially treated cotton gauze that are sandwiched between two epoxy-coated aluminum wire screens for durability. K&N uses a specially formulated grade of oil to treat the cotton gauze layers which causes a tackiness throughout the cotton's microscopic strands creating a powerful filtering media that ensures engine protection.

    Washable, Reusable Filter. K&N designed their high flow air filter to be washable and reusable, giving you up to 100,000 miles before needing to be cleaned out, dependent on driving conditions.. That means there is no need to buy a new filter every few thousand miles, you can just clean the filter, re-oil it, and save money with a K&N Filter Recharge Kit.

    No Tune Required. Unlike other Cold Air Intakes on the market for the 5.4L F-150, this K&N FIPK CAI does not require a computer re-tune. The engineers at K&N really did their homework to improve your truck's power using the stock tune.

    Straight Forward Installation. K&N Series 57 FIPK Air Intake Kit is designed to install easily with just basic hand tools. No extra modifications or special tools are required for proper installation. All necessary parts and instructions are included.

    CARB Certified. Best of all, K&N's Series 57 FIPK CAI is 50-state smog legal under Carb EO #D-269-37.

    Application. The K&N Series 57 FIPK Cold Air Intake System is specifically designed to fit all 2004 to 2008 F-150s powered by the 5.4L V8 engine.

    Please Note. This K&N Cold Air Intake is not designed for F-150s equipped with a body lift.

      Nice Product

      Installed this Cold Air Intake on my 08 5.4L FX4, and the installation wasn't that hard. Just a pointer, when installing the adapter that goes between the throttle body and intake manifold, be very careful with the hardware so it doesn't fall into the intake manifold. Once I had it installed and drove the truck around, really enjoyed the increase in throttle response.
