MSD engineered the Super Conductor Spark Plug Wire Set for Small Block Chevy engines running an HEI-style distributor cap. This set delivers the ultimate combination of spark energy transfer and EMI suppression. Built for race engines with headers, this 8.5mm wire set provides custom-length wires that fit perfectly while withstanding the heat and abuse of high-performance environments.
At the core of each wire lies a copper alloy conductor that keeps resistance under 50 ohms per foot, ensuring maximum spark energy reaches the plugs. MSD helically winds over 40 feet of conductor into each foot of wire, forming a powerful ferromagnetic EMI choke that keeps electronic noise inside the wire and away from your vehicle’s sensitive systems. To reinforce strength and flexibility, MSD integrates Dupont Kevlar into the core structure.
A proprietary silicone/synthetic outer jacket resists high heat, abrasion, and wear—making this set ideal for demanding street or track use. Each wire includes 90° plug boots and HEI-style terminals, finished with MSD’s Dual Crimp terminals for maximum durability and performance.
