The Ultra 40 Plug Wire Set - LS1 - Sleeved by Moroso is specifically designed for modified LS1 engine builders and performance enthusiasts who require reliable spark delivery in high-RPM conditions. This wire set is ideal for those pushing their LS1 engines to the limits with increased boost, nitrous, or aggressive ignition timing.
Featuring a low-resistance conductor core wrapped in durable sleeve protection, the Ultra 40 design effectively reduces electromagnetic interference (EMI) that can hinder ignition performance. The sleeved construction protects the wires from abrasion, oil exposure, and heat cycling, which are critical factors in high-performance applications, especially in tight engine compartments.
Owners of modified LS1 engines upgrading to stroker kits, turbo conversions, or naturally aspirated power builds will find this wire set essential for maintaining spark integrity. Installation is straightforward with a plug-and-play design, allowing users to easily replace the factory harness without any modifications.
