Calibrated For Peak Flow Precision And Competitive Demands

The Industrial Injection 0433175275-R6 Race6 Nozzles are engineered for high-output performance in 2001–2004 GM 6.6L Duramax LB7 engines. Flowing at 44 liters per minute, 100% over stock, these nozzles provide the capacity needed for competition-level fuel delivery and are essential when running high-flow CP3 pumps and large-frame turbochargers. Each unit is precision-machined to maintain clean spray patterns and balanced atomization across all cylinders, reducing the risk of hot spots or uneven combustion under extreme pressure. This level of fueling is ideal for fully built motors with aggressive tuning strategies and well-matched airflow components. The Race6 series is not intended for daily-driven or lightly modified vehicles due to its volume and fueling demands. Installation should always be handled by experienced professionals and accompanied by a custom tune to ensure optimal efficiency and engine safety. With individual units sold for flexibility, builders can fine-tune or fully overhaul as needed. These nozzles represent the top tier of diesel fueling hardware for LB7 owners chasing peak performance.
