High-performance wires offer a smoother acceleration and improved engine response, ensuring consistent spark delivery and optimizing engine efficiency. It provides buckles to prevent spark plugs and wires from tangling, making it easy to organize! The wire is made of high-quality materials, which is heat-, highly insulated, and can better prevent wire leakage. It maximizes electrode temperature, has durability and dirt resistance, and improves power output and efficiency.
