    MSD's 8.5mm Super Conductor plug wires deliver low resistance without electronic interference, using a copper alloy conductor wound tightly around a ferro-magnetic center core to choke off EMI while sending maximum spark energy to the plug. Dual Crimp terminals grip both the wire's sleeve and its conductor separately for a secure connection at each end.

    • Wire Type: 8.5 Super Conductor
    • Application: GM LS Engines
    • Boot Material: Silicone, Multi-Angle
