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 indications of a faulty fuel injector include rough engine idling, noticeable power loss, or increased black smoke from the exhaust. If left unaddressed, the injector may fail to deliver fuel, leading to misfires and uneven engine operation. The most significant risk is internal engine damage due to improper combustion or fuel dilution of the engine oil.

Installation Tip

Ensure the injector seat in the cylinder head is perfectly clean and free of carbon deposits before installing the new injector. Avoid rotating the injector during tightening, as this can damage the sealing surfaces.

Service Note

When replacing fuel injectors, it is critical to replace the fuel filter and bleed the fuel system to remove any air.
