K&N 03-04 Ford Expedition V8-4.6L/5.4L Performance Intake Kit

If you're looking to get more out of your 2003 or 2004 Ford Expedition with a V8-4.6L or 5.4L 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 how it performs. This kit replaces your restrictive factory airbox with a system that allows for a higher volume of airflow, directly contributing to increased horsepower and torque.

The intake tube is made from high-density polyethylene using a rotational molding process, which helps increase airflow volume. It comes with K&N's washable and reusable High-Flow Air Filter, featuring oiled cotton media. This oversized, conical filter is built to last, letting you go up to 100,000 miles between cleanings under normal highway driving. A custom heat shield is included to keep hot engine bay air away from the intake, ensuring cooler, denser air enters the engine for better combustion. K&N backs this kit with their Million Mile Limited Warranty.

Installation is typically straightforward and can often be completed in under an hour. This kit is a popular choice for Expedition owners looking for a straightforward way to improve their vehicle's performance.
