2007 and 2008 Ford F-150 Gets 9.88 More Horsepower with K&N Air Intake System

 
 
The Ford F150 series is one of the best selling vehicles in the United States and closes in on the million unit mark annually. The F-150 is tailored for the person who uses it for a daily commute as well as for serious towing or hauling. K&N Engineering has designed a high-flow air intake system (63-2574) for the 2008 Ford F150 4.6 liter V8 engine. The 2007 Ford F150 models with the 4.6 liter engine use K&N's 57-2574 performance intake system.

K&N dynamometer testing shows a 9.88 horsepower gain @ 4200 RPM with these systems. K&N designers removed the OE air box and intake and built a larger intake system to open up the breathing capacity necessary for the 4.6 liter engine to get the full amount of air it needs.

K&N's air intake design provides excellent air filtration and lower restriction than the factory air box system for an immediate power gain. All the OE emissions devices are reused and the MAS placed in a location that works with factory settings.

A large chrome top K&N high flow air filter (RF-1041) allows 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.

The heat shield assembly is installed into the engine bay using factory mounting points. The heat shield isolates the K&N air filter from the hotter temperatures around the engine and allows it to receive a consistent flow of fresh cooler air.

The 63-2574 can be easily installed in 90 minutes or less and is backed by the K&N Million Mile Limited Warranty.
