The Industrial Injection 0 433 175 519-R4 is a precision-engineered extrude honed fuel injector nozzle designed for 2003-2004 Dodge Cummins diesel engines. This R4 series nozzle delivers 130% over stock flow rate (55 LPM) and supports up to 250 horsepower when paired with dual CP3 injection pumps.

Key Features:

• Extrude honed and EDM (Electrical Discharge Machining) manufacturing process for precise fuel atomization
• Hone balanced design ensures consistent performance across all cylinders
• 130% fuel flow increase over factory nozzles (55 liters per minute)
• Supports up to 250 horsepower output
• Factory replacement design for direct fitment on 2003-2004 Dodge Cummins applications
• Requires dual CP3 high-pressure fuel pumps for optimal performance

The extrude honing process polishes and perfects the internal fuel passages, resulting in improved fuel delivery, better combustion efficiency, and increased power output. Each nozzle is precision-balanced to ensure even fuel distribution and smooth engine operation. This nozzle is ideal for enthusiasts seeking reliable performance gains while maintaining factory-style fitment and reliability.
