GPI Spark Plug Wire Set - Extreme Heat - Long Length - Fluorescent Green (2014+ GM LT Engines) - gpiLT-XTR-FGR-LONG
Extreme-Heat Spark Plug Wires for High-Boost GM LT Engines
The GPI gpiLT-XTR-FGR-LONG Spark Plug Wire Set is engineered specifically for forced induction GM LT engines that operate in high-heat, high-EGT environments. This Extreme Heat version features upgraded high-temp boots and an additional heat sleeve to ensure long-term reliability under turbocharged or supercharged conditions.
Built in a long-length configuration (16.00? overall including boots), this wire set is designed for 2014+ GM LT cars and trucks equipped with GPI valve cover kits or relocated coil mounting. Each wire uses a 30 ohms-per-foot high-inductance design (averaging ~400 mH per foot) with a 200 TPI copper winding and a .085 - .090? conductor diameter for consistent spark energy and excellent EMI/RFI noise suppression.
Finished in a high-visibility fluorescent green sleeving with 45° coil boots and 45° spark plug boots, these wires deliver clean routing, secure engagement, and standout under-hood appearance. Every set is engineered, hand-built, and hand-tested in the USA.
