Features Improve startup performance, which makes the car start faster and more smoothly Enhance spark plug ignition, effectively improving engine horsepower Increase the efficiency of electricity generation and charging, extend battery lifespan Significantly improve engine combustion efficiency, reduce fuel consumption, economical and practical Improve the brightness of the headlights, safer for night driving Specification The vehicle's negative current typically returns to the battery's negative terminal through various electrical components. Since the car body is made of steel, the original current loop design may create resistance, leading to inefficient current flow or power loss, which can negatively affect electrical components. Connecting electrical components directly to the battery's negative terminal using a high-performance grounding wire can greatly improve current flow and enhance the overall performance of the vehicle's electrical system Features Improve startup performance, which makes the car start faster and more smoothly Increase the efficiency of electricity generation and charging, extend battery lifespan Significantly improve engine combustion efficiency, reduce fuel consumption, economical and practical Improve the brightness of the headlights, safer for night driving Specifications Condition: Material: PVC Color: Blue Quantity: 5 pieces Size: 100cm/39.4in (2 pieces), 80cm/31.5in (2 pieces), 60cm/23.6in (1 piece) Package Weight: approximately 457g Fitment: Universal Package List 5 x Car Grounding Cable
