Quick Overview

Turn your Audi A4 B8 into a head turner with this DTM Style Carbon Fiber Rear Diffuser.

Sku # : Audi-B8-A4-DTM-Diffuser-ER

Set your Audi B8 A4 apart from all the others with a unique Carbon Fiber Rear Diffuser. This Audi B8 A4 DTM Style Carbon Fiber Rear Diffuser is truly a one of a kind piece, with a very aggressive design and perfect fitment, it is definitely the diffuser to have!  The Audi B8 A4 DTM Style Carbon Fiber Rear Diffuser is professionally crafted with high quality REAL carbon fiber and finished with a clear coat for a product designed to last and not fade due to UV exposure.  Installation is simple and only takes a matter of 30 minutes to turn your Audi A4 B8 into a head turner.

NOTE: Like all Carbon Fiber and FRP products on the market, this product must be test fitted & prepped before installing it. Often, slight modifications are required such as trimming, sanding, filing, or smoothing the surface in order to get best fitment and appearance. This is NOT an OEM product, fitment will NOT always be perfect straight out of the box. We recommend having this product installed by a company that has experience working with AFTERMARKET body kit pieces, not a standard collision repair center that only works on insurance claims. Images below show an accurate representation of THIS PRODUCT, properly installed by a professional installer. We also install this product at our own installation facility in southern California.
