Akrapovic Carbon Fiber Diffuser - BMW F91/F92/F93 M8The 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 M8 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. Fitment notice: With Akrapovi diffuser, hands free trunk lid opening closing sensor is not working.
