Inside, this G8 is an example of keeping it clean and classy. Bryan added the stealthy Demon8 Designs triple-stack gauge pod to help him monitor everything going on with the G8. Two Aeroforce Interceptor gauges borrow data from the factory OBD-II system and relay it to Bryan in real time. The center AEM wideband O2 air/fuel gauge lets him keep an eye on the engine tune-up to make sure everything is running safely and as expected. The unique Holden shift knob was a nice touch, although Bryan doesn’t spend much time using it as the factory-equipped 6L80-E transmission takes care of the shifting by itself.
