Description

The 214601 is a complete injector replacement kit for the 2003-2004 5.9L 24V Cummins — 6 injectors, 6 new connecting tubes, 6 fuel lines, and 2 grid heater gaskets in one box. The 24V Common Rail platform is sensitive to injector wear: rough idle, white smoke at startup, falling fuel economy, and balance-rate codes across multiple cylinders are all signs it's time. This kit gives you everything needed for a complete injector job without chasing parts from three different suppliers.

Whether you're a daily-driver or running a mild tune, this kit is sized for the 2003-2004 specifically — the early 24V Common Rail had a different injector design than the later 2004.5+ trucks, and using the wrong injector pack creates a no-start scenario. The included grid heater gaskets cover the disassembly required to access the injectors.

The new connecting tubes and fuel lines are not optional. Old tubes are the #1 cause of new-injector contamination on the 24V platform, and old fuel lines crack or weep when disturbed during the install. Replace everything in one shot to avoid a second trip back to the shop.

Features

• Complete Kit — 6 Injectors + 6 Connecting Tubes + 6 Fuel Lines + 2 Grid Heater Gaskets
• Direct OE Replacement for 2003-2004 5.9L 24V Cummins Common Rail
• Built for the Early 24V Platform — Not a 2004.5+ Injector
• Stock Calibration — No Tune Required
• $660 Core Charge — Fully Refundable Within 45 Days of Return

Notes

• The new connecting tubes and fuel lines must be installed with the new injectors. Old tubes contaminate new injectors at startup and void Industrial Injection's warranty.
• Cores must be returned within 45 days for the $660 core charge to be refunded. Late returns forfeit the core deposit.
