This is the stock looking twin gauge setup that we're using in our turbo'd M3. This setup is also included with every M3 turbo kit we sell. If you have a supercharger or a turbo kit on your M3 and do not have a boost or wide-band gauge, this is the setup for you. The kit includes a steering column plate (black) that simply replaces your stock unit and has pod mounts for perfectly displayed gauges, an AEM wideband gauge (AEM 30-4100) and AEM boost gauge (AEM 30-4406). Gauges can be pointed any direction and the steering column plate looks identical to the one removed with the exception of the pod mounts. This is a must have for boosted M3s.
