GPI Spark Plug Wire Set - Long Length - Purple (2014+ GM LT Engines) - gpiLT-PUR-LONG
Extended-Length Performance Spark Plug Wires for LT Engines
The GPI gpiLT-PUR-LONG Spark Plug Wire Set is built for LT owners running GPI Valve Cover Kits or custom coil locations that require additional wire length without compromising ignition performance. Designed for 2014+ GM LT car and truck engines, this long-length (16.00? overall) wire set delivers clean routing and reliable spark energy for stock and naturally aspirated applications.
These wires feature 30 ohms per foot high-inductance construction with an average of ~400 mH per foot, combined with a 200 TPI copper winding and .085 - .090? conductor diameter. The result is excellent EMI/RFI noise suppression and consistent ignition performance on modern EFI LT platforms. Each wire uses 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, ensuring the durability, precision, and quality GPI is known for.
