GPI Spark Plug Wire Set - Extreme Heat - Long Length - Orange (2014+ GM LT Engines) - gpiLT-XTR-ORA-LONG
Extreme-Heat Ignition Wires for High-EGT LT Builds
The GPI gpiLT-XTR-ORA-LONG Spark Plug Wire Set is purpose-built for forced-induction GM LT engines operating in high-heat environments. This Extreme Heat version features upgraded boots and an additional heat sleeve to withstand elevated exhaust gas temperatures common with turbocharged and supercharged applications.
Configured in a long-length design (16.00? overall including boots), this set is ideal for 2014+ GM LT cars and trucks running GPI valve cover kits or relocated coil setups. Each wire uses a 30 ohms-per-foot high-inductance design averaging ~400 mH per foot, combined with a 200 TPI copper winding and a .085 - .090? conductor diameter for excellent spark delivery with outstanding EMI/RFI noise suppression.
Finished in a high-visibility orange sleeving with 45° coil boots and 45° spark plug boots, these wires offer clean routing, secure engagement, and long-term durability. Every set is engineered, hand-built, and hand-tested in the USA.

FAQs
When should I choose the Extreme Heat LT spark plug wires?
These wires are ideal for turbocharged or supercharged LT engines that see higher exhaust gas temperatures and require additional thermal protection around the ignition system.
Are these compatible with naturally aspirated LT engines?
Yes, they will fit naturally aspirated LT engines, but the Extreme Heat version is typically recommended only when added heat protection is needed due to boost or tight engine-bay conditions.
