Its a known fact that the RX-8 grounds fail and can cause major vibrations from the engine at idle That is why the crew at Texas Rotary Experts decided to design a grounding kit that accentuates the rotary foundation of the RX-8. The grounding kit is cut for a perfect fit and is ready for plug and play. It will help to reduce roughness due to lack of proper grounding.  The terminals connect to the engine block, the lower intake manifold, the fender, and the fan ground under air intake. For the engine block the ground goes down by the coolant drain plug. The distribution block is no longer included in the v2 of our grounding kit. Supplied with the kit are wire loom and zip ties.
