    MSD's Race Tailored 8.5mm Super Conductor wire set is built for big block Chevy engines running a low-profile distributor. A copper alloy conductor helically wound around a special core keeps resistance under 50 ohms per foot while choking off electro-magnetic interference before it reaches other electronics. The assembly is wrapped in a heavy-duty sleeve resistant to abrasion and high heat, and finished at each end with MSD's Dual Crimp terminals.

    FAQ

    What is this wire set designed to fit?

    This MSD Super Conductor wire set is tailored for big block Chevy engines running a low-profile distributor, and fits race engines equipped with headers or an MSD distributor.

    What is the resistance rating of this wire set?

    The helically-wound copper alloy conductor keeps resistance under 50 ohms per foot, which MSD states is the lowest resistance of any helically wound wire.

    What is the wire's conductor made of?

    The conductor core uses Dupont Kevlar material for added tensile strength, with over 40 feet of conductor wound into every foot of wire for EMI suppression.

    What type of terminals does this wire set use?

    Each wire is finished with MSD's Dual Crimp terminals, which use one crimp for the wire sleeve and a separate crimp to grasp the conductor for a secure connection.
