K&N 57 Air Intake for 4.6L V8
This intake works really well on the Ford 4.6L V8. I installed with a throttle body spacer on a 2004 Ford Expedition. The Expedition is heavy. No doubt about it but with this combo you really feel the difference in power. Fuel economy is up to 20mpg on the highway. Ordered the Heart Throb exhaust kit but have not installed it yet. The 4.6L is a fun engine to add accessories to as it can really produce alot of power with the right upgrades.
