The MSD 8.5 mm 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 of spark energy so more reaches the spark plug. The conductor is wound extremely tight around a special center core. So tight, that there is over 40 Ft. of conductor wrapped into a single foot of plug wire. This winding procedure, combined with a ferro-magnetic impregnated center core, produces an extremely effective electro magnetic interference (EMI) choke.Product Features:Copper alloy conductor has a resistance value of less than 50 ohms per foot for superior sparkFerro-magnetic impregnated core creates an effective EMI chokeForty feet of conductor is wound into a single foot of wire for high EMI suppressionConductor core features DuPont Kevlar material for increased tensile strengthDurable outer sleeve is a proprietary compound for resistance to high heat or abrasionStainless steel terminals feature dual crimp tabs to grip wire conductor and outer jacket separately.
