K&N Performance Intake Kit for 1997-2004 Ford F-150 (V6-4.2L) - 57-2550

Fits 1997-2003 Ford F-150 (Base, XL, XLT) and 2004 Ford F-150 Heritage (XL, XLT) with the V6-4.2L engine.

The K&N 57-2550 Performance Intake Kit replaces your restrictive factory air filter and intake housing to improve airflow and throttle response. This system features a high-density polyethylene (HDPE) rotationally-molded tube designed to increase the volume of air reaching your engine. By streamlining the intake path, this kit provides a measurable increase in horsepower and torque for your Ford truck.

Engineered for long-term durability and protection, the kit includes an oversized, conical High-Flow Air Filter with oiled cotton media that provides excellent filtration while allowing you to drive up to 100,000 miles between services under normal highway conditions. A custom-fit heat shield is included to isolate the air filter from high engine bay temperatures, ensuring a cooler, denser air charge. The entire system is designed to bolt on using factory mounting points, typically requiring less than 90 minutes for installation.
