Gintani/OE Engineering in Van Nuys, CA. Lots of discussion of this on our sister E90Post forum.
Moderately worthwhile at $400-500 (not sure exactly what they're charging now). Enough of a difference to feel, but not nearly enough to make the car feel like an M. If your buddy really wants hp it probably makes a lot more sense to trade up to a Z4M than spend a bunch on mods to the N52.
