The Iveco Injector 504091504 is a remanufactured common rail diesel fuel injector—also known as Bosch 0445120054 or cross-referenced with 2855491 and 0986435545—designed for precise fuel delivery in heavy-duty Iveco trucks and related equipment. This high-performance injector ensures accurate fuel atomization, optimal combustion, and reliable power output while meeting emission standards and maximizing fuel efficiency.

Primary Role of the 504091504 Injector

In common rail systems, the injector controls the exact timing and quantity of diesel injection under high pressure. It features advanced solenoid technology for rapid response, durable components to withstand extreme conditions, and precise calibration to reduce smoke, noise, and fuel consumption. A well-functioning injector delivers smooth acceleration, strong torque, and lower operating costs—essential for commercial fleets.

Compatible with popular Iveco models, particularly those with NEF/F4 series engines (3.9L and 5.9L):

• Iveco Eurocargo (Eurocargo I-III series: 60E, 75E, 80E, 90E, 100E, 110E, 120E, 130E, 140E, 150E, 160E, 170E, 180E, and similar)
• Select Iveco Tector variants
• Related applications in Irisbus, Heuliez, and cross-compatible equipment like Case/New Holland backhoes (e.g., 580SM, 590SM series with F4HE/F4AE engines)

This Bosch-manufactured part is a direct fit for many mid-range Eurocargo trucks from the 2000s–2010s. Always verify compatibility via your vehicle’s VIN, engine code (e.g., F4AE3, F4HE0484), or existing injector markings.

Common Signs of Injector Failure

Over time, injectors like the 504091504 can develop issues from fuel contamination, wear, carbon buildup, or electrical faults. Typical symptoms include:

• Rough idling, misfires, or reduced engine power
• Excessive black smoke from the exhaust
• Increased fuel consumption
• Check engine light with codes related to injector balance, rail pressure, or misfires
• Hard starting or stalling under load

These problems are frequent in high-mileage Eurocargo fleets and can lead to poor performance, higher emissions, or costly secondary damage if ignored.

Replacement Options for 504091504

• New genuine Bosch/Iveco OEM — for factory reliability, perfect calibration, and warranty
• Remanufactured units — professionally rebuilt with new nozzles, solenoids, and seals; often 40-60% cheaper than new, with solid warranties
• Aftermarket or repair kits — for targeted fixes like nozzle replacement or cleaning

Power Source Engine Parts Reman injectors match OEM specs and are popular among operators for cost savings without compromising durability. Professional installation and coding (via diagnostic tools) are recommended to ensure proper ECU adaptation and balanced operation.
