M Performance rear diffuser, carbon fibre

100 percent high-tech. 100 percent motorsport character. 100 percent show-stopper. The M Performance rear diffuser is made of carbon fibre, which is meticulously crafted by hand. With their chiselled look, the striking fins ensure that the car looks more dynamic and masculine than ever.

For BMW M340i xDrive without trailer tow hitch. The automatic tailgate operation must be deactivated.
