MSD Super Conductor Spark Plug Wire Set Big Block Chevy HEI

The MSD Super Conductor spark plug wire set is a high-performance ignition wire kit for Big Block Chevy engines with an HEI distributor. These wires are built to deliver a strong, consistent spark to each cylinder, which supports reliable starting, smooth running, and good throttle response in street, strip, and performance applications.

Key Features:

• Spiral-wound core design: The Super Conductor wire uses a low-resistance spiral core. It carries spark energy efficiently while helping to suppress radio frequency interference (RFI/EMI).
• High-temperature insulation: A silicone jacket and insulation system protects against engine heat, oil, and abrasion.
• Pre-assembled and ready to install: The set is made for Big Block Chevy HEI applications and has factory-installed terminals and boots.
• Secure connections: Boots and terminals are made to seal and grip firmly at the distributor and spark plugs, which helps prevent misfires and arcing.
• Race-proven brand: MSD is a well-known name in performance ignition systems, including distributors, coils, and ignition boxes.

These wires work well with aftermarket and stock-style ignition systems. They are a dependable upgrade over worn or standard replacement spark plug wires. Check the individual product listings for the specific wire color and configuration options.
