+1 - all that, and you don't have to be concerned with warranty issues, either. This is a value-add update, not a sneak-behind-their-back tack-on. Besides the added power, it also provides a few distinguishing parts like the new engine cover, opened-up intake, and some badging that can stay with the car. Nickel-and-diming on a $50K+ car just doesn't make sense, especially when you consider the added sophistication of the 8AT, dynamically-adjustable suspension and all the other things that set the F30 apart from the E9x generation.
