The MSD 8.5mm Super Conductor wire is the performance wire. Engineered from the inside out, the 8.5 offers everything you have ever wanted in a wire, incredibly low resistance without electronic interference! In a single 12 In. length of Super Conductor wire there is only 40 to 50 ohms of resistance! That is the lowest resistance of any helically wound wire. To accomplish this, we use a copper alloy conductor due to it's great voltage carrying capabilities. The low resistance results in less loss in spark energy so more reaches the spark plug. The conductor is wound extremely tight around a special center core. This winding procedure, combined with a ferro-magnetic impregnated center core, produces an extremely effective electro magnetic interference (EMI) choke.
