About this part
The ADRO diffuser is made of 100% hand-crafted carbon fiber and will bolt up easily to your OEM BMW M3 or M4 rear bumper with no fitment gaps. This diffuser features built-in aero canards, 100% wet carbon fiber construction, and exhaust cutouts designed to fit both OEM and most aftermarket exhaust tips. This diffuser kit will completely transform the look of the back of your BMW M3 or M4 and is much easier to install than a lot of the other diffusers on the market.
