Engineered from the inside out, this MSD 8.5mm Super Conductor wire set delivers incredibly low resistance without electronic interference. A single 12-inch length carries only 40-50 ohms of resistance, thanks to a copper alloy conductor wound over 40 feet per foot of wire around a ferro-magnetic core, producing an effective EMI choke. A silicone and synthetic outer sleeve resists high heat and abrasion, and MSD's Dual Crimp terminals grip both the wire sleeve and conductor for a secure connection.
