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.

The K&N 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.
