MSD 31179 Super Conductor Universal Spark Plug Wire Set - 8.5mm 6-Cylinder

The MSD 31179 Super Conductor Spark Plug Wire Set is a universal-fit, cut-to-length wire set designed for 6-cylinder engines. Built around MSD's legendary 8.5mm Super Conductor technology, these wires deliver maximum spark energy to the plugs while keeping EMI/RFI interference where it belongs — inside the wire and away from sensitive engine electronics.

At the core of each wire is a copper alloy conductor helically wound over a ferro-magnetic impregnated center core. This design produces resistance of just 40–50 ohms per foot — the lowest of any helically wound wire — while providing RFI suppression equivalent to a 1,500-ohm wire. Each foot of finished wire contains approximately 40 feet of tightly wound copper conductor for exceptional conductivity. The thick 8.5mm synthetic/silicone outer jacket over an extra-heavy glass braid provides outstanding heat resistance and durability.

This universal set ships with extra-long wires so you can custom-trim each lead to the exact length needed for your specific routing. The spark plug terminal and boot come pre-installed on one end; distributor cap boots and terminals are included separately so you can cut, strip, and crimp the open end to fit. A Mini-Stripper-Crimper tool is included to complete the job.

Key Features:

• 8.5mm Super Conductor construction — 40–50 ohms/ft resistance with superior EMI/RFI suppression
• Universal fit — extra-long wires cut to your desired length for custom routing
• Wire lengths included: 2 x 40", 2 x 36", 2 x 32", and one 36" coil wire
• Dual-terminal compatibility — includes both socket-style (early type) and spark plug-style HEI boots and terminals
• Multi-angle spark plug boots and terminals factory-installed on one end
• Ferro-magnetic impregnated center core for effective EMI choke
• Tough synthetic/silicone outer jacket with extra-heavy glass braid insulation
• Includes Mini-Stripper-Crimper tool for custom termination
• Legal for use on emissions-controlled, non-emissions-controlled, and racing-use vehicles

The MSD 31179 is an ideal solution for performance enthusiasts, racers, and restorers who want precise wire routing on inline-6 or V6 engines. Sold as a complete set.
