2006-2007 Duramax Dragonfly 50Hp Injector Nozzle (0433171924DFLY)

Industrial Injection Dragonfly 50HP extrude-honed injector nozzle for the 2006-2007 LBZ 6.6L Duramax. Each nozzle is sourced direct from the OE supplier and then extrude-honed in-house to balance flow and spray pattern across the set.

This is the daily-driver step in the lineup — rated 50HP / 15% over stock at 23 LPM, well suited to mileage and towing-focused builds that want a small fueling bump without moving up to a larger nozzle. Direct drop-in for the stock injector body.
