So far our 2007 is getting about 17 to the gallon if we're lucky but I will be in the process of tearing out the stock plugs and wires (since the factory stuff is junk) and put a K&N drop in filter. It's still under warranty till feb of 09 so the more progresive filter like the AIRRAID cone will replace our filter box after that to not void our warranty.The mileage should go up. Everyone who has done this to thiers have a change in gas and a better running engine. People on this forum seem to say the same thing. I'm crossing my fingers of course!
