Ford Expedition Cold Air Intakes utilize premium reusable filters for cleaner air intake. You know you'd perform better breathing in air from the Rockies than air from inner-city Beijing, and the same goes for your car. Cleaner, cooler air is healthier for your ride because it creates a better fuel burn. And, your Ford Expedition Cold Air Intake delivers not only better air, but more of it. A cold air intake for Ford lets you realize your Expedition's greatest power potential.
