MSD 31549 8.5mm Super Conductor Spark Plug Wire Set Red Chevy Sprint Car

The MSD 31549 is an 8.5mm Super Conductor spark plug wire set built specifically for small block Chevy Sprint Car applications. Designed from the ground up to handle the extreme demands of magneto-powered race engines, this set delivers an unbeatable combination of ultra-low resistance and maximum EMI suppression in a tight-fit, close-clearance configuration.

At the heart of the Super Conductor wire is a helically-wound copper alloy conductor that produces only 40?50 ohms of resistance per foot ? the lowest resistance of any helically wound wire available. The copper alloy construction is far superior to stainless steel in voltage-carrying capability, making it ideal for the high current and voltage output of a Pro Mag or other powerful racing magneto.

Despite the low resistance, EMI suppression is not sacrificed. By tightly winding the conductor around a ferro-magnetic impregnated center core, the wire creates an EMI choke effect that keeps interference contained within the wire ? protecting sensitive on-board electronics from ignition noise. The outer sleeve is constructed from a proprietary blend of silicone and synthetic material, providing outstanding resistance to high heat, abrasion, and tears under race conditions.
