INJECTOR

This is a Genuine Bosch mechanical fuel injector (part number 0 432 193 646) designed for the 5.9L Cummins ISB 24-valve diesel engine in 1998–2002 Dodge Ram 2500 and 3500 trucks rated at 175 horsepower. It atomizes and delivers fuel into the combustion chamber at a precise opening pressure (300–314 bar) to ensure efficient, clean combustion. Over time, injector nozzles wear or clog, leading to rough idle, hard starting, white/black smoke, or power loss, so replacement restores proper engine performance and fuel economy.
