Taylor Spiro Pro 8 mm spark plug wires have a high-conductivity resistor conductor that’s spiral-wound with a stainless steel wire for more power through the wire and to the plug. They have ten times less resistance than standard wires, which helps eliminate electronic interference to radios, ignitions and computer-controlled devices. Spiro Pro wires use two layers of 100% silicone on the outside with a temperature rating of 600° without additional sleeving—the highest on the market. The spark plug boots are low profile and have double spring lock spark plug terminals. Use Spiro Pro spark plug wires for performance at a reasonable price.
