2006-2007 Duramax Stage 1 20% Over Injector Nozzle (0433171924-R1)

Industrial Injection's Stage 1 honed nozzle is a precision-machined replacement tip for the 2006-2007 6.6L LBZ Duramax injector, flowing 24 LPM — roughly 20% above stock. It's a clean way to add a modest fueling bump during an injector rebuild without committing to a full big-power build.
