      Filter Like You Wouldn't Believe. This K&N intake system is equipped with a top-end filter that lets air flow through but cleans it as well. The secret is many layers of cotton material coated in oil. The air passes through them easily, but the oil captures tiny particles. The filter is capped with an aluminun screen that's protected with epoxy for additional strength.

      Solid Build Quality. This cold air intake set is designed from durable materials that will hold up through regular use. The intake pipe is made from polyethylene and offers insulation and strength.

      Lifetime Warranty. K&N offers a lifetime limited warranty on each of its cold air intake kits.

      Accepted Everywhere. Some cold air intakes aren't accepted in states like California where smog standards are high. This intake comes with Carb EO #D-269-37. allowing it to pass the standards in all 50 states.

      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.

              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.
