ACDelco 2171432 Professional Multi-Port Fuel Injector

The ACDelco 2171432 is a Professional-grade replacement fuel injector designed to restore precise fuel delivery to your engine. As an electro-magnetic valve, it meters the correct amount of fuel into the engine's intake manifold or cylinders, atomizing it with incoming air to form a combustible mixture for efficient combustion.

The engine management computer controls the injector by sending an electric current to the solenoid winding, causing the needle valve to open and allowing pressurized fuel to be atomized into the intake airstream. This design ensures accurate fuel metering across all operating conditions, helping maintain engine efficiency, throttle response, and emissions performance.

The ACDelco 2171432 provides a reliable, cost-effective solution to restore proper fuel system function. Also referenced as part number 217-1432.
