Extreme Heat Spark Plug Wires for High-EGT GM LT Builds
The GPI Extreme Heat Spark Plug Wire Set - gpiLT-XTR-FOR-STD is purpose-built for forced-induction GM LT engines that see elevated exhaust gas temperatures. This Xtreme Heat configuration features upgraded high-temperature boots and an additional protective heat sleeve, making it the correct choice for turbocharged and supercharged LT applications where standard ignition wires are not enough.
This set uses a standard-length design that fits 2014+ GM LT car and truck engines with factory coil locations. Each wire is constructed with a 30 ohms-per-foot high-inductance core (averaging ~400 mH per foot) combined with a 200 TPI copper winding and .085 - .090? conductor diameter to provide excellent EMI/RFI suppression and stable spark delivery under boost.
Finished in a bold fluorescent orange sleeving with 45° coil boots and 45° spark plug boots, these wires ensure clean routing, secure connections, and long-term durability. Every set is engineered, hand-built, and hand-tested in the USA for uncompromising quality.
