Ultra 40 Wire Set 8.5mm GM LS/LT 11.0 Red

The Ultra 40 Wire Set 8.5mm GM LS/LT 11.0 Red by MOROSO is designed for serious LS and LT engine builders who require maximum ignition reliability and consistent spark delivery. This premium ignition wire set is ideal for high-performance applications, whether you're tuning a street car, track vehicle, or dedicated racing engine.

Featuring an 8.5mm wire diameter, this wire set provides optimal conductor cross-section for low resistance and efficient energy transfer to the spark plugs. The high-temperature silicone jacket is rated for sustained underhood temperatures, resisting cracking and electrical leakage, which is crucial for maintaining performance under extreme conditions. The deep red finish not only enhances visual appeal but also offers UV and ozone resistance.

Engine enthusiasts running LS or LT powerplants will benefit from this wire set's ability to withstand boost, heat, and extended RPM pulls. The design minimizes RFI (radio frequency interference) while ensuring spark timing accuracy across the full RPM range, making it a reliable choice for those looking to optimize combustion and power output.
