GPI Spark Plug Wire Set - Extreme Heat - Standard Length - White (2014+ GM LT Engines) - gpiLT-XTR-WHT-STD
Extreme Heat Spark Plug Wires for Boosted GM LT Engines
The GPI Extreme Heat Spark Plug Wire Set - gpiLT-XTR-WHT-STD is engineered specifically for forced-induction GM LT engines that operate under elevated exhaust gas temperatures. This Xtreme Heat configuration features upgraded high-temperature boots and an additional protective heat sleeve, making it the correct ignition solution for supercharged and turbocharged LT builds where standard wires can fail.
Designed in a standard-length configuration, this set fits 2014+ GM LT car and truck engines with factory coil locations. Each wire utilizes 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 deliver excellent EMI/RFI suppression and stable spark energy under boost.
Finished in a clean white 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.
