Extreme Heat Ignition Wires for Boosted GM LT Applications
The GPI Extreme Heat Spark Plug Wire Set - gpiLT-XTR-BLK-STD is purpose-built for forced induction GM LT engines that operate under elevated exhaust gas temperatures. This Xtreme Heat version features upgraded high-temperature boots and an additional heat sleeve to protect the ignition system in turbocharged and supercharged applications where standard wires fall short.
Designed in a standard-length configuration, this set fits 2014+ GM LT car and truck engines retaining factory-style coil placement. Each wire utilizes a 30 ohms-per-foot high-inductance design (averaging ~400 mH per foot) with a 200 TPI copper winding and .085 - .090? conductor diameter, delivering excellent EMI/RFI noise suppression and consistent spark energy under boost.
Finished in a clean black sleeving with 45° coil boots and 45° spark plug boots, these wires ensure proper routing, secure connections, and long-term durability. Every set is engineered, hand-built, and hand-tested in the USA for uncompromising quality and reliability.
