PREMIUM EARTH KIWAMI New product. Application: For 37 Alto Features 22sq equivalent extremely thick braided wire with 6mm diameter terminals. Includes two copper washers for contact points. * While the genuine earth enhancement cable sold by DIY-LIFE (intended to connect to the negative terminal of the battery) has heat-resistant sheathing, this product is not sheathed and is intended to connect the engine and body. Therefore, it uses braided wire, which excels in heat dissipation. * Special processing makes the wire less likely to bend and easier to install. * Uses high-quality braided copper wire (plated surface treatment) from a Japanese manufacturer.
