Stage 3 race injectors heading to Canada. Cat C15 race-only injectors. Stage 3 completely rebuilt in-house at Rochester Diesel with all new parts. These injectors contain a 12 mm plunger that has been DLC coated. The nozzle has been custom EDM'd and micro-flowed through the process of extrude honing to maximize fuel flow. Overall the Stage 3 injector flows 300% more fuel than the largest stock C18 injector. There is also extensive machine work done to each injector body to increase fuel flow.
