315-3381 4 Pcs Fuel Injector — Cat 416 420F

This set includes four high-performance fuel injectors, crucial for delivering the correct amount of fuel into each cylinder for optimal engine combustion. Built to exacting standards, these injectors ensure precise fuel atomization and consistent spray patterns, outperforming worn units that cause uneven running. Operators may notice rough idling, hesitation during acceleration, increased exhaust emissions, or a loss of engine power when these injectors are malfunctioning.

Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Initial symptoms of failing injectors include uneven engine idle and a noticeable lack of power, especially under load. If left unaddressed, this can lead to increased fuel consumption, rough running, and potential damage to other engine components due to imbalanced combustion. Continued operation risks significant engine performance degradation.

Installation Tip

Thoroughly clean the injector seats in the cylinder head before installing the new injectors to ensure a proper seal. Avoid forcing the injectors into place, as this can damage the injector tips or the cylinder head.

Service Note

It is recommended to inspect or replace the fuel filter and check the fuel lines for any signs of contamination or wear when servicing the fuel injectors.
