For the rear of your Audi A4 S-line or S4 Sedan B9.5, there's this diffuser in dry carbon. It gives a more aggressive rear profile and pulls the back end together into a tight, sporty whole.
The diffuser is made from dry carbon fiber and finished with a UV-resistant coating, so the dry carbon stays protected against discoloration and keeps its deep gloss.
With its OEM fit, the part lines up seamlessly with the original diffuser of the A4 and S4 Sedan with chassis code B9.5.
Delivery by specialized courier
This part is too long for DHL and PostNL. We ship it with a specialized courier that delivers carbon undamaged. On the day of delivery you can track the driver live on the map, so you know exactly when they'll arrive. The shipping cost for this is €62.50, shown at checkout.
