Product Description
Industrial Injection 0433175519-R6 Extrude Honed Nozzle — 400HP for 2003–2004 5.9L Cummins
The Industrial Injection 0433175519-R6 extrude-honed nozzle is built for the early common-rail 5.9L Cummins (2003–2004). This R6 race nozzle delivers approximately 192% over stock flow (~70 LPM) and supports ~400 HP+ with the correct airflow, fuel supply, and tuning. Ideal for competition or off-road builds that need serious fuel delivery.
Why Choose This Nozzle
- Proven R6 calibration: race-level flow increase for big-power builds.
- Extrude-honed & balanced: engineered for consistency cylinder-to-cylinder.
- Early 5.9 CR fitment (2003–2004): direct-fit nozzle for your OE injector body.
Fitment
- 2003–2004 Dodge Ram 2500/3500 with 5.9L 24-valve Cummins (early common rail)
Note: 2004.5–2007 (late 5.9) uses a different nozzle. Verify build date and injector style before ordering.

FAQs
Will this fit my 2004 Ram 5.9?This nozzle fits the early 5.9L common-rail (2003–2004). Trucks built 2004.5–2007 use different nozzles. Check your build date and injector style before ordering.
Do I need dual CP3 pumps?At ~192% over stock flow, we strongly recommend dual CP3s or a high-output CP3 to hold commanded rail pressure under load. See our Dual CP3 Kit and CP3 pump options.
Is this sold as a set of six?No, this listing is for one nozzle. Order quantity 6 for a complete set. We list it individually to accommodate replacements or mixed builds.
Is tuning required?Yes. Custom ECM calibration is required to manage idle quality, smoke, timing, and pulse width for a 192% over nozzle.
Is this street legal?No. This is a competition/off-road part and is not legal for use on pollution-controlled vehicles on public roads.
