Thank you for viewing. This is a 5-piece grounding cable kit. 【What is Grounding?】 Grounding involves connecting low-resistance wires from the battery's negative terminal to various parts of the car to ensure a smooth flow of electricity to components that use it. After electricity flows to lights, spark plugs, etc., it is consumed and returns to the battery through the car body. Grounding involves adding grounding cables to the negative terminal side to return the electricity directly to the battery. 【What kind of cars need it?】 As your car ages, the original cables and metal parts deteriorate and rust, reducing their effectiveness... ・Poor fuel efficiency... ・Dim headlights... ・Stereo noise... ・Unstable idling... These symptoms may appear. 【Bring your car back to its original performance!】 Grounding smooths the flow of negative electricity, leading to: ・Smooth engine start! ・Improved fuel efficiency! ・Stable idling! ・Brighter headlights! ・Cleaner exhaust gas! ・Improved speaker sound quality! By deciding on grounding points and connecting them, various effects can be expected. The kit includes easy-to-wire flexible cables, battery terminals, and bolts and nuts for easy connection. The blue cables will dress up your engine room. 【Grounding Cable Kit Contents】 ・Cables (Blue) 100cm x 2 80cm x 2 60cm x 1 ・Battery terminal x 1 ・Bolts and nuts x 4 each ・Grounding point chart ・Compatible with both 12V/24V ■Free shipping nationwide ■Shipping method: Yu-Packet Post Ships within 2-3 days of purchase, and delivery to your post box will be completed in about 4-6 days.
