Leave them stock and save for a 12 bolt or 9" with 4.10's. I'm guessing your M6.

3.73 will increase your RPM a little, not that much gain over your 3.42, and decrease your gas mileage some. If you want to change gears and make a significant change go with 4.10 (even less MPG). My advice is keep the 3.42 and don't worry about the import guys.

If your that worried about fuel mileage get some juice and then you only kill your MPG's when you want to and you won't fear the imports any more.

Ok... first is it an a4 or m6?? second like a few others said... you won't get the best of both worlds... just not gonna happen... If you want gas mileage, stick with what you got. If you want the take off... and you have an a4 go with 3.73's if you have an m6 and want take off, go with 4.11's or 4.10's....
