GPI Spark Plug Wire Set - Extreme Heat - Long Length - Black (2014+ GM LT Engines) - gpiLT-XTR-BLK-LONG
Extreme-Heat Ignition Wires for Boosted LT Engines
The GPI gpiLT-XTR-BLK-LONG Spark Plug Wire Set is engineered for forced-induction LT builds that see elevated exhaust gas temperatures. This Extreme Heat version features an upgraded boot design and an additional heat sleeve to protect the ignition system under sustained boost and high thermal loads.
Built in a long-length configuration (16.00? overall, including boots), this set is ideal for 2014+ GM LT car and truck engines running GPI valve cover kits or relocated coil mounting. 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 without sacrificing spark energy.
Finished in black with 45° coil boots and 45° spark plug boots, this set delivers 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
When should I choose the Extreme Heat LT spark plug wires?
Choose the Extreme Heat version for supercharged or turbocharged LT engines that experience higher exhaust gas temperatures and need added thermal protection.
Are these wires required for naturally aspirated engines?
Naturally aspirated setups typically do not require the Extreme Heat version. Standard or long-length GPI LT wires are usually sufficient unless additional heat protection is desired.
