my understanding is, like with all BMW parts, its the parts that are warrentied. not the work, no matter if its done at dealer. i remember a friend who paid for performance brakes on his e90, something went wrong but BMW honored it no problem... those were installed elsewhere, didnt matter.

so i guess in short, if he wants a total peace of mind, do it at the dealer. but if hes whining about savin some change, take it elsewhere - the warrenty will still be honored on those parts if something breaks. (now if those parts where INCORRECTLY INSTALLED, thats an entirely different story)

SOMEONE CORRECT ME IF IM WRONG HERE
