1994-1998 Cummins Race3 Honed 150HP Injectors (0432131715-R3)

Industrial Injection's Dragon Fly R3 150HP honed race injector for 1994-1998 Dodge Ram 2500/3500 5.9L 12V Cummins. A stepped-up performance injector designed to pair with a built 12mm Dragon Fly P7100 fuel pump and support roughly 700 HP — the right injector for race trucks and serious weekend warrior builds that have outgrown the 100HP R1.

The R3 designation refers to honed nozzle work for additional fueling capability over stock. Actual truck power depends on turbo, fueling pump, and tuning. No core is required — keep your old injectors. These are sold individually so you can buy six for a complete set or one to replace a single injector in an existing set. Each injector ships with 1.5mm copper washers (D3920174).

Recommended turbo pairing for a single-turbo street/race build at this fueling level is the PhatShaft Viper series (compounds will give better drivability and EGT control under heavy towing or load).
