Sierra 18-8609 E-Go Throttle Body Adapter for Marine Fuel Injection Cleaning Systems

The Sierra 18-8609 E-Go Throttle Body Adapter is a purpose-built accessory for the Sierra E-Go Marine Fuel Injection Cleaning System. This adapter is designed to connect the E-Go cleaning system directly to the throttle body inlet, allowing fuel injector cleaner to flow through and dissolve stubborn fuel deposits that accumulate on injectors, intake ports, and combustion chamber surfaces.

Compatible with all marine engines equipped with throttle body fuel delivery systems, the 18-8609 is the go-to adapter when performing a throttle body-fed fuel system service. It is commonly used alongside the Sierra 18-8600 E-Go Fuel Injector Cleaning Kit and Sierra 18-8606 E-Go Blast Fuel Injector Cleaner for a complete, professional-grade marine fuel system service.
