Cummins 4070114 Fuel Injector Assembly

This fuel injector assembly corresponds to Cummins part number 4070114 and Bosch nozzle holder assembly 0432191365. It features a CDC (Common Rail Diesel) type electromagnetic actuator and a DLLA155P1108 multi-hole nozzle designed for the Cummins 6BTAA 5.9L engine platform. The injector delivers high-pressure fuel spray at optimized cone angles for efficient combustion chamber mixing. The component is manufactured to OEM specifications for durability under high-cycle thermal and mechanical loads. It serves as a direct replacement for worn or failed injectors causing rough idle, excessive smoke, power loss, or elevated fuel consumption. Cross-references include Bosch KBAL105P51 and nozzle designation DLLA155P1108. Installation requires torque calibration to manufacturer standards and high-pressure line inspection.
