MSD's Super Conductor 8.5mm spark plug wires deliver incredibly low resistance without sacrificing electromagnetic interference (EMI) suppression. Each 12-inch section of wire carries only 40-50 ohms of resistance, among the lowest of any helically wound wire, thanks to a copper alloy conductor wound tightly around a ferro-magnetic impregnated center core that chokes EMI inside the wire so it can't interfere with other electronics. The silicone-blend outer sleeve resists high heat, abrasion, and tears, while Dual Crimp terminals secure both the wire sleeve and the conductor for a durable connection.
