GPI Spark Plug Wire Set - Long Length - Gray (2014+ GM LT Engines) - gpiLT-GRY-LONG
Extended-Length Performance Spark Plug Wires for LT Engines
The GPI gpiLT-GRY-LONG Spark Plug Wire Set is engineered for LT owners running GPI Valve Cover Kits or custom coil routing that requires additional reach without sacrificing ignition performance. Designed for 2014+ GM LT car and truck engines, this long-length (16.00? overall) configuration maintains clean routing while delivering stable spark energy for stock and naturally aspirated applications.
These wires utilize 30 ohms per foot high-inductance construction with an average of ~400 mH per foot, paired with a 200 TPI copper winding and a .085 - .090? conductor diameter. The result is excellent EMI/RFI noise suppression and consistent ignition performance for modern EFI LT platforms. Each wire features 45° coil boots and 45° spark plug boots for secure, OEM-style fitment.
Every set is engineered, hand-built, and hand-tested in the USA, delivering the durability, quality, and performance GPI is known for.
