Short beds are also available on this popular truck that closes in on the million unit mark annually. K&N Engineering has designed a high-flow air intake system (57-2574) for 2007 & 2008 Ford F150 4.6 liter V8 engine.

K&N's air intake design provides excellent air filtration and lower restriction than the factory air box system. This results in an immediate power gain.

A large chrome top K&N high flow air filter (RF-1041) allows virtually free flowing air into the intake tube and increased dirt capacity. K&N also incorporated a radius adapter to help smooth out air flow coming through the air filter. K&N air intake systems are designed to increase filtering capacity and improve throttle response.

The heat shield is engineered to isolate the oversized K&N high flow air filter from engine bay heat and allows it to receive a consistent flow of fresh cooler air.

The 57-2574 can be easily installed in 90 minutes or less and is backed by the K&N Million Mile Limited Warranty. This intake is street legal for 2007 & 2008 Ford F-150 4.6 liter V8 engine in 50 states.
