"This was an easy installation into my truck. All the parts fit in with existing holes with no need for any modifications. Once installed, I saw a difference in initial take off speed; as well as better fuel economy. I am just disappointed that it took me this long to get this intake for my truck. This is a good buy weather you are looking for performance or better fuel economy." —Christopher L from Bremerton, WA bought a K&N 63 Series AirCharger High-Flow Intake Kit for a 2003 Toyota Tundra, 4.7L V8.
