GPI Spark Plug Wire Set - Extreme Heat - Standard Length - Red (2014+ GM LT Engines) - gpiLT-XTR-RED-STD
Extreme Heat Ignition Wires for Boosted GM LT Builds
The GPI Extreme Heat Spark Plug Wire Set - gpiLT-XTR-RED-STD is engineered 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, delivering the thermal protection required for turbocharged and supercharged setups where standard wires can fail.
Built in a standard-length configuration, this set fits 2014+ GM LT car and truck engines with factory-style coil locations. Each wire uses a 30 ohms-per-foot high-inductance design (averaging ~400 mH per foot) with a 200 TPI copper winding and .085 - .090? conductor diameter for excellent EMI/RFI suppression and reliable spark delivery under boost.
Finished in a bold red 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.
