    You want to improve your MPG? slow down.
    That's the only thing that's going to work

      I have one, waste of money. Completely but it sounds really cool when I stomp on the gas.

      I second that. I now go very lightly on the throttle and never drive above 70 I am getting a lot better mileage. Still onlt 15-16 mpg but better than the 12-13 I was getting.

        That's what I did as well, put the stock air box/ filter back on and drive slower. I get 16 mpg... not bad for driving a box!
        That's a BIG rock!
