Audi S5 with the APR Stage III Supercharger Kit

We have done a lot of work for dealers through the years, this was a big project. This was a brand new S5 on the showroom floor and the local Audi dealer wanted us to install the APR stage III supercharger kit. It was sold new with the kit on the car. The customer that bought the S5, loves it and we have been servicing it ever since it was new. We then installed the APR Carbonio intake and APR exhaust. It sounds incredible with the supercharger whine and the V8 growl.
