MSD 32813 Super Conductor 8.5mm Spark Plug Wire Set Black GM LS1

The MSD 32813 Super Conductor Spark Plug Wire Set is a custom-fit, 8.5mm performance ignition wire set designed specifically for GM LS1 engines. Featuring a black jacket and straight plug boots, this set delivers maximum spark energy to the plugs with industry-leading low resistance construction.

At the core of the Super Conductor design is a copper alloy conductor wound extremely tight around a special center core — so tight that over 40 feet of conductor is packed into a single foot of wire. This construction delivers just 40–50 ohms of resistance per 8-inch length, the lowest of any helically wound wire, ensuring minimal spark energy loss.

The tight winding, combined with a ferro-magnetic impregnated center core, creates a highly effective EMI choke that keeps electromagnetic interference contained within the wire and away from sensitive vehicle electronics.

The outer sleeve is built from a proprietary blend of silicone and synthetic material, offering excellent resistance to high heat, abrasion, and tears. Terminals use MSD's Dual Crimp design — one crimp secures the wire sleeve, and a separate crimp locks onto the conductor itself — for a superior, vibration-resistant connection.
