Description

The ICT Billet 551333-L83 is a set of eight dummy fuel injector plugs designed for GM Gen V LT series engines. These plugs are used when converting to a port fuel injection system. They are compatible with 2014-2018 LT1, LT4, L83, L86, and L8B engines that originally came with 7.5mm (.295") injector nozzles.

Constructed from aerospace-grade billet aluminum and made in the USA, this kit includes the mock injectors, retainer bars, and pre-installed seals. A separate plug (551965-PLUG) is required to plug the lifter bore for the high-pressure fuel pump.
