2004.5-2005 Duramax Stage 3 40% Over Injector Nozzle (0433171860-R3)

Industrial Injection Stage 3 40% over injector nozzle for the 2004.5-2005 LLY 6.6L Duramax. Each nozzle is sourced direct from the OE supplier and then extrude-honed at Industrial Injection's facility to balance the spray pattern and flow across the set.

The R3 spec flows 29 LPM — a 40% increase over stock — for crisper throttle response, lower EGTs, and improved atomization with the right supporting tune. Bolt-in replacement for the stock nozzle.
