The filter is an excellent product, but it did not fit as well as the original Power Core filter in my Volant filter box. Had to raise the box cover by 3/4 ".

I should have installed this product a long time ago. Trucks sounds better, runs better and has made a improvement in fuel mileage. The most noticible is the sound of the turbo, in the past a new stock filter would allow turbo sound to be heard for about a day then it was gone. You feel more connected to your truck when you can hear what it is doing. At the same time it's not so loud that it becomes annoying or obnoxious to neighbors.
