Easy installation!! Perfect for classic cars!? The material is high-quality, high-purity aluminum, an original product processed from a pure solid flat plate. Aluminum, when compared only by electrical resistance, has excellent electrical conductivity, second only to copper and gold, following silver, copper, and gold. The resistance values of gold and aluminum are almost the same. The resistance value is about 1.5 times that of copper. Aluminum is lighter than copper, so it conducts more than twice as much electricity as copper when converted to the same amount. "Doesn't aluminum conduct electricity??" It conducts electricity because it's a metal. Aluminum is an element, so it doesn't conduct electricity if it has impurities, surface treatment, anodizing treatment, Alpina treatment, etc. Aluminum is also used inside capacitors. It has a 4-hole M6 specification. It's not a tap. Includes 4 SUS bolts and nuts ※Will not rust Includes 1 set of M5 spacers and butterfly bolts ※M6 change consultation available Includes 1 28cm blue 8AWG assist wire Includes 1 BT mounting flange nut ※SUS bolt and nut can be changed to SUS cap bolt and nut. This is a terminal block that attaches to the screws of the battery case stay. Connect with the included spacer, attach the terminal, and connect it from the existing negative terminal with the assist wire. Please refer to the image. The double-threaded diameter of the spacer is M5 (※M6 change consultation available), so it should fit most cars. Please be sure to check the dimensions of your own car before bidding. It is manufactured on the premise of use with earthing tuning. Because it has 4 holes, it will expand versatility. Because it is an original processed product, please consider processing scratches, scratches, slight dimensional errors, and distortions as a charm ^^; Image 3 is an installation IMG of the same type. We do not accept price negotiations. No shipping on weekends and holidays.
