GPI Spark Plug Wire Set - Extreme Heat - Long Length - Blue (2014+ GM LT Engines) - gpiLT-XTR-BLU-LONG
Extreme-Heat Ignition Wires for High-Boost LT Builds
The GPI gpiLT-XTR-BLU-LONG Spark Plug Wire Set is designed for forced-induction LT engines that operate in elevated exhaust gas temperature environments. This Extreme Heat configuration features an upgraded boot design and an additional heat sleeve to protect ignition components from radiant and sustained thermal loads common to turbocharged and supercharged setups.
Built in a long-length configuration (16.00? overall, including boots), this set is ideal for 2014+ GM LT car and truck platforms running GPI valve cover kits or relocated coil mounting. Each wire utilizes a 30 ohms-per-foot high-inductance design averaging ~400 mH per foot, with a 200 TPI copper winding and .085 - .090? conductor diameter to deliver excellent EMI/RFI noise suppression while maintaining strong, consistent spark energy.
Finished in a bold blue sleeving and equipped with 45° coil boots and 45° spark plug boots, these wires provide clean routing, secure engagement, and durability where it matters most. Every GPI wire set is engineered, hand-built, and hand-tested in the USA.

FAQs
Who should use the Extreme Heat LT spark plug wires?
These wires are recommended for turbocharged or supercharged LT engines that experience higher exhaust gas temperatures and require added thermal protection.
Are these necessary for naturally aspirated LT engines?
Typically no. Naturally aspirated builds are well served by standard or long-length GPI LT wires, unless additional heat shielding is specifically desired.
