GPI Spark Plug Wire Set - Long Length - Fluorescent Green (2014+ GM LT Engines) - gpiLT-FGR-LONG
Extended-Length Ignition Wires for LT Engines with Valve Cover Kits
The GPI gpiLT-FGR-LONG Spark Plug Wire Set is engineered for 2014+ GM LT car and truck engines that require additional reach due to GPI valve cover kits or relocated coil mounting. This long-length (16.00? overall) wire set provides clean routing, consistent boot engagement, and reliable spark delivery for stock and naturally aspirated LT combinations.
Each wire features a 30 ohms per foot high-inductance design, averaging ~400 mH per foot, combined with a 200 TPI copper winding and a .085 - .090? conductor diameter. This construction delivers excellent EMI/RFI noise suppression while maintaining strong ignition energy for modern EFI-controlled LT engines.
Finished in a high-visibility fluorescent green sleeving and equipped with 45° coil boots and 45° spark plug boots, these wires offer OEM-style fitment with added clearance where needed. Like all GPI ignition components, every set is engineered, hand-built, and hand-tested in the USA.

FAQs
When should I choose the long-length LT spark plug wires?
The long-length wire set is recommended when using GPI valve cover kits or modified coil locations that require extra wire length for proper routing and clearance.
Are these wires suitable for forced-induction LT engines?
This wire set is intended for stock and naturally aspirated LT applications. Boosted setups may require a different ignition wire configuration.
