This is a muffler grounding wire that I purchased in bulk before. It can also be used for engine grounding and various other applications. I'm selling it cheap because I don't have a chance to use it! ★ Grounding the muffler removes static electricity, improves exhaust efficiency, and increases power, torque, and response. ★ Total length: 25cm ★ Material: Copper, braided ★ Plated terminals: Hole size is 8mm ★ This is the price for 3 new wires. Please note that it will be sent by regular mail, so it will take about a week to arrive.
