Description
Reliable spark plug wire performance is non-negotiable when you’re running a Small Block Chevy—weak ignition signals mean lost power, misfires, and inconsistent combustion. The MSD Black 8.5mm Super Conductor set eliminates guesswork with proven Super Conductor technology and a spiral core design that cuts electromagnetic interference, ensuring your ignition fires cleanly on every cycle. This is a bolt-on upgrade that delivers measurable improvements in throttle response and engine stability without breaking the bank.
Built for racers and street enthusiasts who demand reliability, this complete wire set features thick-gauge construction and silicone 90-degree boots for a secure fit in tight engine bays. The copper alloy conductor maintains low resistance under load, while HEI-style terminals lock in tight to your distributor cap—no slipping, no wondering if your spark is getting through.
