Ultra 40 Plug Wire Set GM LS - Red

The Ultra 40 Plug Wire Set GM LS - Red from MOROSO is designed for builders and enthusiasts who require reliable ignition harness performance for LS-platform engines. This wire set is essential for addressing common issues in LS conversions and street/strip builds, particularly regarding spark delivery consistency.

Featuring suppression-core construction, the Ultra 40 design minimizes electromagnetic interference while ensuring effective current flow to all eight cylinders. The red jacketing serves as a visual identifier of the wire's heat and abrasion resistance, making it suitable for tight engine bays where wires may come into contact with hot components.

Street engine builders, drag racers, and weekend warriors utilizing LS Gen III, Gen IV, or Gen V platforms will find this wire set beneficial for its durability and performance consistency. The set is designed to work with factory-style terminals, but users should verify compatibility with their specific OEM-style coil packs.
