2004.5-2007 Cummins Reman Stock Injectors w/ Connecting Tubes (215312)

The 215312 is a complete all-in-one stock injector replacement pack for the 2004.5-2007 5.9L Cummins — six remanufactured Industrial Injection stock injectors plus six new Bosch connecting tubes in a single box. When your 5.9L Cummins starts losing power, smoking at idle, or pulling balance-rate codes across multiple cylinders, this is the drop-in fix without sourcing parts from three different 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 the factory OEM spec, which is the reason owners report a smoother idle and more consistent fuel trim after install. Every finished injector is run on a Bosch OEM test stand and gets a build-sheet record before it leaves the line.

The kit ships with six Bosch connecting tubes — a critical inclusion, since old connecting tubes are the most common cause of new-injector contamination and warranty failure on the 5.9L Common Rail platform.

• Complete Set — 6 Reman Stock Injectors + 6 Bosch Connecting Tubes

• Includes New Copper Crush Washers + O-Rings for Install

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

• Cores must be returned within 45 days for the $630 core charge to be refunded. Late returns forfeit the core deposit.
