Industrial Injection 100HP extrude-honed injector nozzle for the 2004.5-2007 5.9L Common Rail Cummins. Each nozzle is brought in direct from the OE supplier and then extrude-honed in-house so the spray pattern and flow are balanced across the set.

This nozzle is rated at 30 LPM — roughly 25% over stock — and supports a 100HP gain with the right tuning and supporting hardware. Direct drop-in for the stock injector body, no other changes required.
