Max Fire Plug Wire Set SBC w/HEI 90 Degree Red

The Max Fire Plug Wire Set SBC w/HEI 90 Degree Red from Edelbrock is engineered for small-block Chevy engines running HEI distributors and 90-degree plug boots. This spark plug wire set addresses a critical ignition system component that directly impacts engine starting reliability, idle quality, and overall combustion efficiency. Whether you're tuning a street engine, restoring a classic muscle car, or dialing in carbureted performance, quality plug wires prevent misfires, reduce electromagnetic interference, and ensure consistent spark delivery across all cylinders.

Built with 8.5 mm spiral core construction, the Max Fire wire set suppresses radio frequency interference while maintaining excellent voltage capacity and heat resistance—essential for high-output ignition systems. The 90-degree plug boots provide the correct geometry for tight engine bay fitment on small-block Chevy applications, reducing strain on terminals and boot connectors during thermal cycling. Red color coding aids in quick visual identification during engine maintenance or troubleshooting. The socket-style terminals ensure secure connection to both the HEI distributor cap and spark plug posts without fouling or corrosion issues that degrade spark quality.

This complete kit suits rebuilds, upgrades, and routine maintenance on any small-block Chevy equipped with an HEI ignition system—from 283 to 400 cubic inches. Installation is straightforward: remove old wires one at a time, noting firing order on the distributor cap, then install new Max Fire wires using the correct 90-degree boot angle for your specific engine block and header configuration. For best results, install fresh spark plugs simultaneously to maximize ignition system performance and fuel economy gains.
