GPI Spark Plug Wire Set - Standard Length - Gray (1999+ GM LS Truck) - gpiTLS-GRY-STD
Dependable Ignition Wires for Stock and Naturally Aspirated LS Trucks
The GPI Spark Plug Wire Set - gpiTLS-GRY-STD is engineered specifically for 1999+ GM LS truck engines operating in stock or naturally aspirated configurations. This Standard Version delivers consistent spark delivery, excellent electrical noise suppression, and long-term reliability for daily-driven trucks, work applications, and street builds.
Built in a standard-length configuration, these wires feature an 11.5-inch overall length including boots, ensuring proper fitment on Chevy LS truck engines 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 provides durability and consistent electrical performance. Finished in a subtle gray sleeving with 45° LS coil boots and 45° spark plug boots, these wires offer secure connections, clean routing, and a factory-plus underhood appearance. Every set is engineered, hand-built, and hand-tested in the USA, delivering unparalleled quality and customer confidence.
