ECS Carbon Fiber Rear Diffuser

For a direct fit, easy to install, visual upgrade, the ECS Carbon Fiber Rear Diffuser for your B8 A4 is a perfect choice. In an afternoon, you can quickly change the look of your Audi's rear bumper to that of a more aggressive style.

Being durable and aesthetically pleasing are two of the biggest reasons carbon fiber has become so popular in motorsports. Whether you are looking to make an addition to your weekend warrior, your show car, or your canyon carver, the rear diffuser will add that special 'finishing touch' you're going to love.
