GPI Spark Plug Wire Set - Extreme Heat - Long Length - Fluorescent Orange (1997+ GM LS Car Engines) - gpiLS-XTR-FOR-LONG
Extreme Heat, Extended-Length Ignition Wires for Boosted LS Engines
The GPI Extreme Heat Spark Plug Wire Set - gpiLS-XTR-FOR-LONG is engineered for forced-induction GM LS car engines that operate under elevated exhaust gas temperatures and require additional wire length for proper routing. This Xtreme Heat version features upgraded high-temperature boots and an additional protective heat sleeve, making it ideal for turbocharged and supercharged LS builds using GPI valve cover kits.
Built in a long-length configuration, these wires feature an overall length of 14.75 inches including boots. They are specifically designed for LS car applications with GPI valve cover kits, where standard-length wires may not provide adequate reach. Each wire uses a 30 ohms-per-foot high-inductance design, averaging ~400 mH per foot, which helps provide excellent EMI/RFI suppression while maintaining a strong, stable ignition signal under high boost.
A 200 TPI copper winding combined with a .085 - .090? conductor diameter ensures durability and consistent electrical performance. Finished in a high-visibility fluorescent orange sleeving with 45° LS coil boots and 45° spark plug boots, these wires deliver secure connections, clean routing, and standout underhood visibility. Every set is engineered, hand-built, and hand-tested in the USA.

FAQs
Who should run the Extreme Heat long-length LS spark plug wires?
These wires are designed for boosted LS car engines running GPI valve cover kits that see higher exhaust gas temperatures and require both added thermal protection and extended wire length.
Why choose the long-length version over standard length?
The long-length configuration ensures proper routing and strain-free connections on LS cars with GPI valve cover kits, where standard-length wires may not reach correctly.
