With the addition of K&N Engineering's new Air Intake System, Ford Super Duty owners can realize a 16+ horsepower gain. K&N's Research and Development Department tested a 2005 Ford F250 6.8 liter V10 on our in-house dynamometer. Results showed a 16.21 horsepower gain @ 4450 RPM.

K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your engine to pull in air with ease compared to the OEM air filter assembly. More air means more power and torque when you need it. With the 57-2567, consumers towing heavy loads should see a difference in performance.

This air intake system uses a conical shaped chrome top high-flow air filter (RC-4630) and powder coated aluminum heat shield in place of the vehicle's stock air box. The result is an air filter that captures harmful particles, provides more surface area, flows more air, and increases service life. This K&N air filter performs for up to 100,000 miles before service is required depending on driving conditions. Improving the air path between the filter and the motor is the rotationally-molded high density polyethylene tube. It offers the most flexibility in design and outstanding horsepower numbers. It takes about 90 minutes or less to install this system with simple hand tools. It is covered by K&N's Famous Million Mile Limited Warranty and is 50 state street legal.
