GM 12677810 Fuel Injector Assembly

GM 12677810 is a gasoline direct injection (GDI) fuel injector designed for Gen V 6.2L V8 engines. It features a 7-hole nozzle spray pattern for optimized combustion efficiency and emissions compliance. The injector operates under high fuel rail pressure typical of direct injection systems. It supersedes OE part number 12668393. This component is calibrated for specific flow rates and spray targeting required by L86, LT1, and LT4 engine applications. The injector assembly includes the solenoid actuator, nozzle valve group, and integrated fuel filter basket. Electrical connector interface matches GM DI injector profile. Installation requires new seals and torque-to-yield fuel rail bolts per GM service procedure. Compatible with flex-fuel (E85) operating strategies where equipped.
