Audi B8 S4 ECS Carbon Fiber Rear Diffuser
Audi designed a beautiful car in the B8 S4, which sets itself apart from everyday sedans with an attitude of subtle dominance from a reserved yet capable package. While it is a stunning example of a luxury sports sedan, we know small touches can change the total appearance.
