Description

The 214311 is a complete stock injector replacement pack for the 2003-2004 5.9L 24V Cummins — six remanufactured stock injectors plus six new Bosch connecting tubes in a single box. When your 24V Cummins starts losing power, smoking at idle, or throwing balance-rate codes, this is the drop-in fix without sourcing parts from multiple suppliers.

Each injector starts as a genuine Bosch core, fully disassembled and rebuilt with brand-new Bosch internals — nozzles, valves, and hardware. Industrial Injection balances each injector to a tighter flow tolerance than factory OEM spec, which is what produces the smoother idle and more consistent fuel trim owners report after install. Every finished injector is tested on a Bosch OEM stand before it leaves the line.

The 2003-2004 24V Common Rail platform uses a different injector design than the later 2004.5+ trucks — confirm your year before ordering. If you also need new fuel lines and grid heater gaskets, see 214601 for the full kit.

Notes

• The included connecting tubes are not optional — old tubes contaminate new injectors at startup and void Industrial Injection's warranty.
