Thank you for viewing. This is a high-power grounding cable that can be used for cars, motorcycles, etc. Limited quantity available while supplies last. The cable uses Dragon Gold, handled by the Japanese manufacturer, Jean Line. Crimping is done using hydraulic tools, and the terminals are made by Nichifu. We have prioritized quality over inexpensive gold plating. (The photo shows a cable compatible with M10 bolts. Usually, M8 bolt terminals are used.) It can be used in various ways for tuning, such as reinforcing the battery's negative terminal, grounding from the engine to the body, and grounding from the muffler to the body. Effects include: Improved sound quality of car audio Changes in engine feel Changes in exhaust resistance of the muffler Improved stability of headlight brightness, etc. Why not try various applications and enjoy the changes in your car? Marks are placed on the terminals. Electricity flows from the terminal with the mark to the terminal without the mark. We offer lengths from 30cm to 60cm, so please comment with the length you need. We will create a dedicated listing for you. Price list 30cm = 2000 yen 40cm = 2700 yen 50cm = 3400 yen 60cm = 4000 yen
