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

An initial indication of a faulty fuel injector can be a rough or uneven engine idle, accompanied by a loss of power. If ignored, the problem can escalate to persistent engine misfires, excessive black smoke from the exhaust, and a significant increase in fuel consumption. Continued operation with defective injectors risks internal engine damage from improper combustion or fuel dilution of the lubricating oil.

Installation Tip

Always ensure the injector bore is meticulously clean and free of any carbon deposits or debris before installing the new injector to guarantee a proper seal. Avoid overtightening the injector hold-down clamp, as this can damage the injector body or the cylinder head.

Service Note

When replacing fuel injectors, it is advisable to inspect the fuel filter for contamination and check the fuel pump for proper operation.
