noticed about 1 or 2 mpg more, not much of a change. but there was a considerable power difference, had a little more kick to it.

I have only had my filter in for about two tanks of gas but I do believe that I am getting about 10-20% better gas mileage. I do not know about other customers but my filter was a bit of a b@$%h to put in and wound up with scuffed knuckles. I think I am getting more power out of the car as a result of the AFE filter but will follow up later once I put new spark plugs and cables on the car.
