Improves Horsepower. The OE Air Intake System in your 2004-2006 4.6L F-150 is restrictive when it comes to the air flow. Replace it with the K&N Air Intake System and feel the true power your pickup is capable of producing. The high-flow K&N filter assembly and smooth intake tube will provide a noticeable increase in horsepower, acceleration and throttle response while still providing excellent filtration.

No Tune Required. Unlike other Cold Air Intakes on the market for the 4.6L V8 F-150s, this K&N Series 77 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 factory tune.

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 filters to be reusable. 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.

Straight Forward Installation. Designed to be a direct fit replacement for the factory intake this K&N Series 77 Cold Air Intake Kit installs with just basic hand tools. No extra modifications or special tools are required for an easy 1 hour installation. All necessary parts and instructions are included.

CARB Certified. Best of all this K&N Cold Air Intake Kit is 50-state smog legal under Carb EO# D-269-37.

Application. This K&N Series 77 High Flow Performance Cold Air Intake is specially designed to fit the 2004-2006 F-150s equipped with the 4.6L V8 engine.

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