The Industrial Injection 0 433 172145-R4 is a high-performance extrude honed injector nozzle designed for Dodge Ram 6.7L Cummins diesel engines (2007.5-2012). This R4 race nozzle delivers 250 horsepower potential at 58 liters per minute (LPM) flow rate, making it ideal for competition vehicles and serious performance builds.
Advanced Extrude Hone Manufacturing Process:
Each nozzle begins as a genuine OE-spec component sourced directly from the original equipment supplier. Industrial Injection then applies their proprietary EDM (Electrical Discharge Machining) and extrude hone processes to precisely enlarge and balance the internal passages. This extensive calibration ensures perfectly matched flow characteristics, smooth operation, and exceptional reliability.
Key Features:
- 250 HP performance gain potential over stock
- 58 LPM flow rate for maximum fuel delivery
- Extrude honed and EDM balanced for precise fuel atomization
- Factory replacement design for direct installation
- Includes new copper crush washer for proper sealing
- Individually flow tested on state-of-the-art equipment
- Built from OE-spec genuine Bosch components
- One year unlimited mileage warranty
Important Requirements:
The R4 nozzle requires dual CP3 high-pressure fuel pumps to support the 58 LPM flow rate. This is a race-level component designed for competition vehicles with extensive fueling modifications including upgraded or dual CP3 injection pumps, proper ECM tuning, enhanced turbocharger systems, and supporting drivetrain components.
Installation Notes:
Sold individually (order six for a complete set). It is highly recommended to have nozzles professionally calibrated to your specific injectors for optimal performance. Proper tuning and adequate air supply are essential to safely manage the increased fuel delivery and power output.
