321-0990 6 Pcs Fuel Injector — Cat 613G

This is a set of 6 CAT Fuel Injectors, precisely engineered to deliver the correct amount of fuel into each cylinder for optimal combustion. Manufactured to meet stringent quality standards, these injectors ensure consistent fuel atomization and spray patterns, unlike worn injectors that can cause poor performance. Operators may observe rough idling, reduced engine power, increased exhaust smoke, and poor fuel economy when these injectors begin to fail.

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

Early signs of failing fuel injectors include rough engine idling and a noticeable decrease in acceleration. If left unaddressed, this can lead to increased fuel consumption, potential engine misfires, and damage to other fuel system components.

Installation Tip

Ensure the injector bores in the cylinder head are perfectly clean and free of any carbon deposits before installing new injectors. Always use new seals and O-rings provided with the injectors.

Service Note

When replacing fuel injectors, it is also recommended to inspect the fuel filter and fuel lines for any signs of blockage or contamination.
