Bosch DLLA160P1308 Common Rail Injector Nozzle

Technical specifications for Bosch common rail injector nozzle DLLA160P1308 (stamping 0433171817). This component serves as the spray tip for Bosch injector assembly 0445110216, primarily applied in BMW diesel engine platforms. The nozzle body is manufactured from high-speed steel grades 18CrNi8 or W6MoCr4V2 to withstand high-pressure fuel erosion and thermal cycling. Precision machining maintains surface roughness below Ra0.05 micrometers ensuring optimal fuel atomization and spray pattern geometry. The nozzle features a 160-degree spray angle as designated by the DLLA160 classification. It functions as a direct replacement part for OEM maintenance and repair of common rail fuel injection systems.
