GPI Spark Plug Wire Set - Extreme Heat - Standard Length - Black (1997+ GM LS Car Engines) - gpiLS-XTR-BLK-STD
Extreme Heat Ignition Wires for Boosted LS Car Engines
The GPI Extreme Heat Spark Plug Wire Set - gpiLS-XTR-BLK-STD is purpose-built for forced-induction GM LS car engines that operate under elevated exhaust gas temperatures. This Xtreme Heat version features upgraded high-temperature boots and an additional protective heat sleeve, making it the right choice for turbocharged and supercharged LS builds where standard ignition wires are pushed beyond their limits.
Configured in a standard-length design, this set is intended for LS car engines with standard coil placement. Each wire uses a 30 ohms-per-foot high-inductance construction, averaging ~400 mH per foot, which helps provide excellent EMI/RFI suppression while maintaining a clean, stable ignition signal for modern EFI systems - even under high boost.
A 200 TPI copper winding combined with a .085 - .090? conductor diameter ensures durability and consistent electrical performance. Finished in a classic black sleeving with 45° LS coil boots and 45° spark plug boots, these wires deliver secure connections, proper routing, and long-term reliability. Every set is engineered, hand-built, and hand-tested in the USA.
