K&N 99-04 Ford F-Series Super Duty V8-5.4L Performance Intake Kit

If you're looking to get more out of your 1999-2004 Ford F-250 Super Duty with the 5.4L V8 engine, this K&N Performance Intake Kit is a solid option. It's designed to help your engine breathe easier, which can lead to a noticeable improvement in both horsepower and torque. This kit replaces your restrictive factory air intake system with a more efficient setup.

The intake tube is made from high-density polyethylene (HDPE) using a rotational molding process, which helps increase the volume of air reaching your engine. It's paired with K&N's well-known washable and reusable High-Flow Air Filter, which uses oiled cotton media. This oversized, conical filter is built to last, allowing you to go up to 100,000 miles between cleanings under normal highway driving. A custom heat shield is included to help block hot air from the engine bay, ensuring your engine gets cooler, denser air for better performance. K&N also backs this kit with their Million Mile Limited Warranty, and it's designed not to void your vehicle's factory warranty.

Installation is typically straightforward and can often be completed in under 60 minutes, meaning you can get back on the road with improved performance relatively quickly. This kit is a popular choice for owners looking for a straightforward way to enhance their truck's engine performance.
