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

A failing fuel injector may cause the engine to run rough, misfire, or hesitate during acceleration. If left unaddressed, fuel delivery issues will worsen, leading to significant power loss and increased exhaust emissions. Continued operation with faulty injectors can result in unburnt fuel washing cylinder walls, leading to premature engine wear.

Installation Tip

Ensure the injector seats in the cylinder head are perfectly clean and free of any debris before installing new injectors. Never reuse old copper sealing washers; always use new ones to prevent leaks.

Service Note

When replacing fuel injectors, it is advisable to inspect the fuel filter and fuel lines for any contamination or blockages.
