I have been looking around for different performance parts to add to my new car and seem to find many options for the N20 engine, but very few that are compatible with the more emission friendly N26 engine. Does anyone own a 428xi GC with the N26 engine and know of brands/products that fit with this car? I am looking for a performance chip, CAI, intercooler, chargepipe, downpipe, exhaust system. Any advice is helpful!
