GPI Spark Plug Wire Set - Extreme Heat - Long Length - Red (2014+ GM LT Engines) - gpiLT-XTR-RED-LONG
Extreme-Heat Ignition Wires for Boosted LT Applications
The GPI gpiLT-XTR-RED-LONG Spark Plug Wire Set is purpose-built for forced-induction LT engines operating under elevated exhaust gas temperatures. This Extreme Heat configuration features an upgraded boot design paired with an additional heat sleeve to protect against radiant and sustained thermal loads common in supercharged and turbocharged builds.
Configured in a long-length format (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 for excellent EMI/RFI noise suppression while maintaining strong, consistent spark energy.
Finished in a bold red sleeving and equipped with 45° coil boots and 45° spark plug boots, these wires deliver clean routing, secure engagement, and durability where it counts. Every GPI wire set is engineered, hand-built, and hand-tested in the USA.

FAQs
Who should run the Extreme Heat LT spark plug wires?
These wires are recommended for turbocharged or supercharged LT engines that experience higher exhaust gas temperatures and need added thermal protection around the ignition components.
Can these be used on naturally aspirated LT engines?
Yes, but the Extreme Heat version is typically unnecessary for N/A setups. Standard or long-length GPI LT wire sets are usually sufficient unless additional heat shielding is desired.
