2003-2004 Cummins Extrude Honed Stage 6 400Hp Injector Nozzle (0433175519-R6)

Stage 6 extrude-honed injector nozzle for the 2003-2004 5.9L Common Rail Cummins, sized at 192% over stock with a 400HP rating. Nozzles are sourced direct from the OE supplier, then extrude-honed and flow-matched in house for a balanced set.

This is the spray tip only — not a complete injector assembly. Nozzles are sold individually so you can build a matched set of six. Install with the included copper crush washer.
