Thank you for viewing. This is a set of 5 red grounding cables. 【What is Grounding?】 Grounding involves connecting low-resistance wires from the negative terminal of the battery to various parts of the car to ensure a smooth flow of electricity to the components that use it. The electricity that flows to lights, spark plugs, etc., is consumed and then returns to the battery through the car body. Grounding involves adding grounding cables to the negative terminal side and returning 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... ・Fuel efficiency worsens. ・Lights become dimmer. ・Stereo noise becomes noticeable. ・Idling becomes unstable. These symptoms may appear. 【Bring your car back to its original performance!】 Grounding smooths the flow of negative electricity, resulting in: ・Smoother engine starts! ・Improved fuel efficiency! ・Stable idling! ・Brighter lights! ・Cleaner exhaust emissions! ・Improved speaker sound quality! By determining the grounding points and connecting the cables, various effects can be expected. The set 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 (Red) 100cm x 2 80cm x 2 60cm x 1 ・Battery terminal x 1 ・Bolts and nuts x 4 each ・Grounding point chart included ・Compatible with both 12V/24V ■Free shipping nationwide ■Shipping method: Yu-packet Post Ships within 2-3 days of purchase and will be delivered to your post box in approximately 4-6 days.
