Over all a nice unit, I suggest maybe making the air box about a 1/4 of an inch narrower its a real tight fit going in and maybe shortening the tube coming off the cover and adding another rubber hose so the cover sets on easier

I have an 05 F 350 4x4 DRW. I have noticed an increase in throttle response. The truck pulls much better than before. And I get an increase of 2 mpg at minimum or better. This is driving 80 mph and not letting off up the hills. I installed this right before a 2000 mile trip, and I wanted to get a true reading on the mileage increase and power. It's worth the $400.00

Gives my truck more power. Have not had it on long enough to see if gas mileage improves.
