Yeah, I’ve decided to skip the diffuser for the initial install. But thought the smaller piece would cover that hole. The second (smaller) piece mentioned in this thread is a piece that 640i already comes with. I will be returning that. Guys at the shop just put my old one back to the car.
So you also didn’t have that part covered initially? The m perf diffuser... do you have the part number? At this point I want to cover it with anything, but ideally with a diffuser (that i wanted to later, but wth) ��
Sorry, I don’t know why i assumed now that you had a 650, probably because you didn’t mention any of the center piece dance
