三菱4D56 喷油器总成 MD338904 / 105148-1560 柴油机原装品质

Mitsubishi 4D56 diesel engine dedicated fuel injector assembly, OEM number MD338904/105148-1560, suitable for Nissan diesel models manufactured after 2000. This part is installed in the injector hole of the cylinder head, responsible for precisely atomizing high-pressure fuel and injecting into the combustion chamber, directly affecting engine power output and combustion efficiency. Installation difficulty is intermediate; recommended to be performed by a professional technician, with labor time about 1.5-2 hours. If idle jitter, weak acceleration, black smoke, or increased fuel consumption occur, it is typically due to nozzle atomization failure or sealing failure and should be replaced promptly.
