GPI Spark Plug Wire Set - Extreme Heat - Standard Length - Yellow (2014+ GM LT Engines) - gpiLT-XTR-YEL-STD
Extreme Heat Ignition Wires for High-EGT GM LT Builds
The GPI Extreme Heat Spark Plug Wire Set - gpiLT-XTR-YEL-STD is engineered for forced-induction GM LT engines that operate under elevated exhaust gas temperatures. This Xtreme Heat configuration adds upgraded high-temperature boots and an additional heat sleeve, delivering the thermal protection required for turbocharged and supercharged setups where standard ignition wires can become a failure point.
Configured in a standard-length layout, 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, providing excellent EMI/RFI suppression and consistent spark energy under boost.
Finished in a high-visibility yellow 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.

FAQs
When should I choose the Extreme Heat wire set?
Choose the Extreme Heat version for turbocharged or supercharged LT engines that see higher exhaust gas temperatures and require added thermal protection around the plugs and coils.
Will these wires fit stock coil locations?
Yes. The standard-length configuration is designed to fit factory LT car and truck coil placement without excess slack or routing issues.
