Features: 1.Improve startup performance, which makes the car start faster and more smoothly 2.Enhance spark plug fire, efficiently reinforce engine horsepower 3.Increase the efficiency of produce electricity and charging, prolong battery lifespan 4.Enormously improve engine combustion efficiency, fuel saving, economical and practical 5.Also improve the brightness of the headlights, more safer to driving at night Specification: Description:_x000D_ Generally, the current on the cathode of the car comes back to the battery cathode through the electric appliances. As all know, the car body is made of steel, so the original current loop design can produce impedance, causing circumstance not smooth or lost and affecting seriously on the electrical appliances. Therefore, connecting the electrical applicances and the car body directly together cathode of the battery with the high-performance enforced ground wire can greatly improve the circumfluence and the top choice to improve the performance of the car electrical appliances!_x000D_ _x000D_ Features:_x000D_ _x000D_ Improve startup performance, which makes the car start faster and more smoothly. _x000D_ Enhance spark plug fire, efficiently reinforce engine horsepower. _x000D_ Increase the efficiency of produce electricity and charging, prolong battery lifespan. _x000D_ Enormously improve engine combustion efficiency, fuel saving, economical and practical. _x000D_ Also improve the brightness of the headlights, more safer to driving at night. _x000D_ _x000D_ Specifications:_x000D_ Condition: 100% Brand New_x000D_ Material: PVC_x000D_ Color: Blue_x000D_ Item Quantity: 5pcs_x000D_ Size: 100cm/39.4in(2pcs), 80cm/31.5in(2pcs), 60cm/23.6in(1pc)_x000D_ Package Weight: approx.457g_x000D_ Fitment: Universal_x000D_ _x000D_ Package List:_x000D_ 5 * Car Earth Cable PackageList:
