Mag-Tune Plug Wire Set SBC 90 Degree Non-HEI

The Mag-Tune Plug Wire Set SBC 90 Degree Non-HEI from MOROSO is a vital upgrade for small-block Chevy engines that utilize traditional distributor-based ignition systems. This product is designed for builders and enthusiasts who prefer non-HEI (High Energy Ignition) configurations, ensuring reliable spark delivery across all eight cylinders. Whether you're working on a street engine, restoring a classic vehicle, or enhancing a performance build, these plug wires are essential for consistent combustion and engine reliability.

The 90-degree boot design of these wires is specifically engineered to accommodate tight engine bays and plug locations typical of vintage small-block Chevy heads. This design helps prevent ceramic cracking and ensures a secure connection, even under conditions of vibration and heat cycling. Additionally, MOROSO plug wires feature high-quality insulation that resists ozone, oil, and heat degradation, which maintains consistent impedance for clean and repeatable firing.

This plug wire set is particularly beneficial for traditional small-block Chevy applications, including 283, 305, 327, 350, and 400 cubic inch engines found in street rods, muscle cars, and vintage race vehicles. The non-HEI specification allows compatibility with various ignition systems, including points, capacitive discharge, magneto, or early electronic distributors, providing flexibility without the need for costly conversion harnesses or module upgrades.
