Review on 🚀 K&N Cold Air Intake Kit: High Performance Horsepower Increase, 50-State Legal: Compatible with 1997-2004 Ford F150, F150 Heritage, F150 Harley Davidson, Expedition (Part Number: 57-2541) by Mark Taylor

Installation was fairly easy on a 2002 F150 Supercrew, although it doesn't quite seat properly and occasionally rattles. Maybe something with my truck or something with the device, I'm not sure. Overall, I definitely noticed more power when accelerating, especially under load. I can accelerate slightly to merge onto the freeway without worrying about being too slow. As for the mpg increase, I've noticed a slight increase, but only under certain circumstances. Stopping and driving in traffic, it makes no difference as I waste too much time idling. When I'm maintaining speed I can typically increase fuel economy by 0.5-1.5mpg which is very good for a truck that had 15-16 fuel economy and is now 16-18. I plan on installing a throttle body gasket in the future and making a few more minor modifications and I think that's where this kit will shine.
