GPI Spark Plug Wire Set - Extreme Heat - Long Length - White (2014+ GM LT Engines) - gpiLT-XTR-WHT-LONG
Extreme-Heat Spark Plug Wires for High-Boost GM LT Engines
The GPI gpiLT-XTR-WHT-LONG Spark Plug Wire Set is engineered for forced-induction GM LT engines operating under extreme heat and elevated EGTs. This Extreme Heat version features upgraded high-temperature boots and an additional heat sleeve to ensure reliable spark delivery in turbocharged and supercharged applications.
Built in a long-length configuration (16.00? overall including boots), this set is designed for 2014+ GM LT cars and trucks equipped with GPI valve cover kits or relocated coils. 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 noise suppression.
Finished in a clean white sleeving with 45° coil boots and 45° spark plug boots, these wires provide precise routing, secure fitment, and a sharp under-hood appearance. Every set is engineered, hand-built, and hand-tested in the USA.
