K&N 01-04 Ford Lightning / F150 H/D Performance Intake Kit

If you're looking to get more power out of your 2001-2004 Ford F-150 or 2004 F-150 Heritage, this K&N performance intake kit is a solid option. It's designed to help your engine breathe easier, which translates to a noticeable increase in horsepower and torque. The kit includes a high-density polyethylene (HDPE) tube that's rotationally molded to help increase the volume of air going into your engine.

This system comes with K&N's washable and reusable High-Flow Air Filter, which uses oiled cotton media. Its large, conical shape means you can go up to 100,000 miles between cleanings under normal driving conditions. A custom heat shield is also included to block hot air from the engine bay, ensuring your engine gets cooler, denser air. K&N backs this kit with their Million Mile Limited Warranty, and it typically installs in under an hour.
