2004.5-2005 Duramax Stage 2 30% Over Injector Nozzle (0433171860-R2)

Industrial Injection Stage 2 30% over injector nozzle for the 2004.5-2005 LLY 6.6L Duramax. Nozzles are sourced direct from the OE supplier and then extrude-honed and balanced at Industrial Injection's facility so each one matches across the set.

The R2 spec flows 27 LPM — a 30% increase over stock — for a step up in fuel atomization, lower EGTs, and a measurable bump in mileage when paired with appropriate tuning. Drops into the factory injector with no other changes required.
