Phillip Wilkerson, Alabama
Gives my truck more power. Have not had it on long enough to see if gas mileage improves.
Houston Hunter Jr, Marrero, Louisiana
I received the filter kit in reasonable time, all of the parts seem to be there. The installation was realitively straightforward. The only real issue that I had was, it took two people and clamps to close the cover enough to install the 10 nuts and washers. One person could NOT do this alone. I bought this unit because I was frustrated with the difficulty in changing the OEM filter without breaking something. Who knew this would not be much better. At least I won'the have to buy a new filter each time.

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
