Description

The MSD Super Conductor Spark Plug Wire Set is a specific-fit ignition component designed for Chevy 454 engines from 1975 onwards with HEI systems. These red 8.5mm wires feature a low resistance design with a helically wound copper alloy conductor. The wire's construction includes a ferro-magnetic impregnated center core to suppress electromagnetic interference and a durable outer sleeve made from a proprietary blend of silicone and synthetic material to resist heat and abrasion.
