Fits select 2004-2008 Ford F-150, Ford Expedition, and Lincoln Mark LT models (V8-5.4L).

The K&N 57-2556 Performance Air Intake Kit is engineered to eliminate the airflow restrictions of your vehicle's factory induction system. At its core is a high-density polyethylene (HDPE) rotationally-molded intake tube that increases airflow volume to your engine for a noticeable improvement in horsepower and torque. This system utilizes an oversized, conical High-Flow Air Filter featuring oiled cotton media that provides superior filtration and can go up to 100,000 miles between cleanings under normal highway conditions.

Designed for a straightforward installation, the entire kit typically bolts on in less than 90 minutes using standard hand tools. The included custom heat shield protects the intake air from high engine bay temperatures, ensuring a cooler, denser charge reaching the engine. This system is backed by K&N’s Million Mile Limited Warranty and is designed to work without voiding your vehicle warranty.
