I don't feel like this mod is worth the $. If it was 1/5th the price, then we can talk, or if it's part of a COMPLETE intake system, from the filter all the way to the intake ports (which would ASLO get port/polished) then I'd expect moderate gains.

If just boring out the thottle body was worthwhile for some horsepower, and won't harm mpg too much, why wouldn't BMW have just produced a wider mouth tb??
