GPI Spark Plug Wire Set - Standard Length - Black (1999+ GM LS Truck) - gpiTLS-BLK-STD
Reliable Ignition Wires for Stock and Naturally Aspirated LS Truck Engines
The GPI Spark Plug Wire Set - gpiTLS-BLK-STD is designed specifically for 1999+ GM LS truck engines running stock or naturally aspirated configurations. This Standard Version delivers consistent spark energy, excellent noise suppression, and long-term durability for daily-driven trucks, tow rigs, and performance-oriented street builds.
Built in a standard-length configuration, these wires feature an 11.5-inch overall length including boots, making them a proper fit for Chevy LS truck applications with factory-style coil placement. Each wire uses a 30 ohms-per-foot high-inductance design, averaging approximately 400 millihenries per foot, which helps suppress EMI and RFI interference while maintaining a clean, stable ignition signal for modern EFI systems.
A copper conductor with 200 TPI winding paired with a .085 - .090? conductor diameter ensures durability and consistent electrical performance. Finished in a clean black sleeving with 45° LS coil boots and 45° spark plug boots, these wires provide secure connections, proper routing, and a factory-plus appearance. Every set is engineered, hand-built, and hand-tested in the USA, delivering unparalleled quality and customer confidence.
