The Moroso Mag Tune ignition wire set fits Chevrolet small block engines with HEI distributors and under-header routing, using 90-degree unsleeved boots for tight spaces. Intended as a direct-fit replacement, the set preserves original routing and lengths for accurate plug-to-coil connections during routine maintenance or engine rebuilds.
