The T1R Earthing System provides valuable grounding for your vehicle's electrical system. This 4 point grounding system substantially reduces electrical noise in your vehicle, which can intefere with the performance of components such as the ignition, distributor, etc. Consequently, the earthing system helps minimize inefficiency and power loss, allowing the engine to perform optimally. Noticeable effects include smoother power delivery and improved throttle response. Highly recommended for older vehicles and heavily modified engines.
