GPI Spark Plug Wire Set - Long Length - Fluorescent Orange (2014+ GM LT Engines) - gpiLT-FOR-LONG
Extended-Length Ignition Wires for LT Engines with GPI Valve Covers
The GPI gpiLT-FOR-LONG Spark Plug Wire Set is built for 2014+ GM LT car and truck engines that require additional reach due to GPI valve cover kits or relocated coil mounting. With a true 16.00-inch overall length (including boots), these long-length wires ensure clean routing, proper boot engagement, and consistent spark delivery for stock and naturally aspirated LT setups.
Each wire uses a 30 ohms-per-foot high-inductance design averaging ~400 mH per foot, paired with a 200 TPI copper winding and a .085 - .090-inch conductor diameter. The result is excellent EMI/RFI noise suppression without sacrificing ignition energy - ideal for modern EFI-controlled LT platforms.
Finished in a high-visibility fluorescent orange sleeving and equipped with 45° coil boots and 45° spark plug boots, this set delivers OEM-style fitment with the extra length your build requires. Every GPI wire set is engineered, hand-built, and hand-tested in the USA.
