Diesel Exhaust Fluid (DEF) Dosing Module / Urea Injector

Condition: New Bosch DeNOx / Denoxtronic DEF Dosing Injector Module. Cooling fins: prominent stacked metallic discs surrounding the body act as a heat sink to prevent the DEF fluid from boiling or crystallizing due to extreme exhaust temperatures. Electrical connector: black plastic plug triggers the internal solenoid valve to control fluid delivery. Fluid nozzle: long black tube at the bottom acts as the injection nozzle protruding directly into the exhaust pipe.
