GPI Spark Plug Wire Set - Extreme Heat - Standard Length - Blue (2014+ GM LT Engines) - gpiLT-XTR-BLU-STD
Extreme Heat Ignition Wires for Boosted GM LT Engines
The GPI Extreme Heat Spark Plug Wire Set - gpiLT-XTR-BLU-STD is engineered specifically for forced-induction GM LT platforms operating under elevated exhaust gas temperatures. This Xtreme Heat configuration features upgraded high-temperature boots and an additional heat sleeve, providing the thermal protection required for turbocharged and supercharged applications where conventional ignition wires can become a weak point.
Built in a standard-length layout, this set fits 2014+ GM LT car and truck engines retaining 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, delivering excellent EMI/RFI suppression and stable spark energy under boost.
Finished in a vibrant blue 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 to meet the demands of high-performance LT builds.
