The MSD 8.5mm Super Conductor is the ultimate performance wire. Its extremely low resistance combined with the ability to suppress electro magnetic interference is a combination that defies the common laws of physics.Less resistance means m ore energy is going to make it to the spark plug to ignite the air/fuel mixture. The Super Conductor uses a copper alloy conductor resulting in less than 50 ohms per foot of wire. This ensures that the most energy possible makes it to the spark plug. This combination is encased in a heavy duty sleeve that will withstand abrasion and high temperatures.Cap off each end with our dual crimp terminals and you have the best wire available.Made in USA Important: For models with the wires routed over the valve covers.
