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

The Mag-Tune Plug Wire Set SBC 90 Degree Non-HEI from MOROSO is an essential ignition system upgrade for small-block Chevy engines running traditional distributor-based setups. Designed specifically for builders and enthusiasts working with non-HEI (High Energy Ignition) configurations, this plug wire set delivers reliable spark delivery across all eight cylinders without the complexity of modern electronic ignition retrofits. Whether you're assembling a street engine, restoring a classic, or fine-tuning a performance build, quality plug wires are fundamental to consistent combustion and engine reliability.

The 90-degree boot configuration on these wires is engineered to fit tight engine bays and tight plug locations typical of vintage small-block Chevy heads, preventing ceramic cracking and ensuring a secure connection under vibration and heat cycling. MOROSO plug wires feature quality insulation that resists ozone, oil, and heat degradation, maintaining consistent impedance across the entire ignition event for clean, repeatable firing. The non-HEI specification ensures compatibility with points, capacitive discharge, magneto, or early electronic distributors—giving you flexibility in your ignition system choice without requiring costly conversion harnesses or module upgrades.

This plug wire set is ideal for traditional small-block Chevy applications including 283, 305, 327, 350, and 400 cubic inch engines in street rods, muscle cars, and vintage race vehicles. Installation is straightforward—simply route wires away from exhaust and moving engine components, confirm proper firing order (1-8-4-3-6-5-7-2 for standard SBC), and verify tight boot seating at both distributor cap and spark plug. Builders appreciate MOROSO's attention to detail and durability, making this set a trusted choice for long-term reliability in both show-quality restorations and hard-driven performance builds.
