HKS Circle Earth Grounding System:
Circular Grounding System - By utilizing a 24 karat gold plated distribution block and multiple grounding points, improved idle and drivability are often obtained as the additional grounding points equalize resistance and voltage between various ground points. Each 8 gauge spiral twined cable is wrapped with signature HKS purple insulation to protect and add color to the Circle Earth System.
