Thank you very much for viewing. Although the effect is not visible, this is a muffler earth wire that Toyota has adopted as a genuine part, calling it an "earth wire." Please search for "muffler earth wire effect." ★ When the correct terminal is crimped to the correct thickness of copper wire with the correct tool, numbers are stamped as shown in image 3. In the case of this product, it is 8sq copper wire, so it is crushed with the tool's "8" and stamped with "8". Both terminals are for M10. Most of the bolts on the muffler flange part of Japanese cars are M10. Since M8 and M6 washers are included on the vehicle body side, it supports all kinds of vehicles. The washers are made of top-brand stainless steel. The flat braided copper wire is TBC-made 15mm wide, and the crimp terminals are Nichifu's [JIS mark]. This product is 200mm, but it can be changed to 300mm for an additional 220 yen. Copper wire part 200mm Total length including terminals 260mm (All approximate) If you have any other requests, please feel free to comment. ※ Warning Strictly prohibited to copy product images and descriptions. ★ Shipping is done by "Yu-Packet Post mini," which is anonymous, trackable, and insured.
