GM LS Truck Spark Plug Wire Set 45-Deg - Orange

The GM LS Truck Spark Plug Wire Set 45-Deg Orange from Scott Performance is purpose-built for enthusiasts and mechanics upgrading or maintaining LS-series engines in trucks and performance vehicles. This high-performance ignition solution replaces factory wiring to deliver superior spark delivery and reliability, particularly in modified engines where precise timing and consistent combustion are critical to power output and engine longevity.

Each wire features a spiral-core construction with 10 mm diameter conductors, engineered to reduce electromagnetic interference and provide clean signal transmission to the coil pack. The 45-degree plug boots are angled to fit GM LS-series coil pack designs, ensuring proper boot-to-plug seating without stress or arcing. Orange color coding aids in organization and visual diagnostics during maintenance, while the spiral-core design also improves heat dissipation under sustained high-RPM operation typical of performance builds.

Mechanics and engine builders working with LS1, LS2, LS3, and related LS-series powerplants will find this wire set essential for turbo, supercharger, and naturally aspirated builds where OEM components no longer meet performance demands. Installation is straightforward—the kit includes all wires needed for a complete replacement, and the 45-degree connector angles are optimized for coil-on-plug configurations common to modern LS swaps. Weight of 1.8 lbs keeps the complete assembly lightweight while maintaining durability for extended track use and street driving.
