The MSD 31653 is a set of Super Conductor spark plug wires designed for Chevrolet 307, 350, and 327 engines from 1971-1974. These 8.5mm wires feature a low resistance of 50 ohms per foot, achieved through a helically wound copper alloy conductor around a ferro-magnetic impregnated core.

The wire set includes 90-degree spark plug boots and socket-style distributor terminals. The outer sleeve is made from a blend of silicone and synthetic materials to resist high heat, abrasion, and tears. The construction includes Dupont Kevlar for added tensile strength and a special center core that creates an EMI choke to prevent interference with vehicle electronics.
