Description
OEM spark plug wires can’t keep up with modified Small Block Chevy engines—they leak EMI and degrade under heat, robbing you of consistent spark delivery and ignition reliability. The MSD 8.5mm Super Conductor wire set eliminates these problems with a low-resistance copper alloy conductor and ferro-magnetic core that suppresses interference while maintaining superior spark energy. If you’re running an HEI distributor and demand dependable performance without guesswork, this is the upgrade your ignition system needs.
