GPI Spark Plug Wire Set - Extreme Heat - Standard Length - Fluorescent Green (2014+ GM LT Engines) - gpiLT-XTR-FGR-STD
Extreme Heat Ignition Wires for Boosted GM LT Engines
The GPI Extreme Heat Spark Plug Wire Set - gpiLT-XTR-FGR-STD is engineered specifically for forced-induction GM LT engines operating under elevated exhaust gas temperatures. This Xtreme Heat version features upgraded high-temperature boots and an additional protective heat sleeve, making it ideal for turbocharged and supercharged applications where standard ignition wires are pushed beyond their limits.
Built in a standard-length configuration, this set fits 2014+ GM LT car and truck engines with factory coil placement. Each wire uses a 30 ohms-per-foot high-inductance design (averaging ~400 mH per foot) combined with a 200 TPI copper winding and .085 - .090? conductor diameter to deliver excellent EMI/RFI suppression and consistent spark energy under high boost.
Finished in a high-visibility fluorescent green sleeving with 45° coil boots and 45° spark plug boots, these wires provide clean routing, secure connections, and long-term durability. Every set is engineered, hand-built, and hand-tested in the USA to meet the demands of serious LT performance builds.
