OP - Optional part
The stunning carbon fibre diffuser is offered as an option with the choice of a high-gloss or matt finish.
It is a completely new design from the one that comes as standard on the car, and it gives the rear of the M5 a more aggressive and sporty feel.
It shows off the tailpipes to their full extent and is a perfect accompaniment to the side mirror caps.
This Rear Carbon Fiber Diffuser - Matt, comes with red/white Akrapovič logo.
Fitment notice: The diffuser cannot fit with genuine trailer tow hitch.
With Akrapovič diffuser, hands-free trunk-lid opening/closing sensor is not working.
