Show original supplier description
The 3D Design F06 / F12 / F13 6-Series M-Sport Rear Diffuser is crafted to enhance the visual appeal of your BMW's lower rear fascia. Constructed from 1x1 Carbon Fiber weave (CFRP) with a gloss clearcoat finish, this diffuser offers an OEM-level surface texture and consistent fitment. It is designed specifically for use with four-tip exhaust configurations and attaches directly to the factory M-Sport lower valance, adding significant presence without compromising the vehicle's elegant design. Developed and manufactured in Japan, 3D Design components are known for their precision, durability, and practicality, blending motorsport influences with street functionality. This rear diffuser is designed for the BMW F12 / F13 6-Series and the F06 6-Series Gran Coupe, provided they are equipped with the M-Sport Package. Important Fitment Note: This rear diffuser requires the factory M-Sport Package rear bumper and is not compatible with non-M-Sport trims.
