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 might initially cause noticeable misfires or a rough idle, especially when the engine is cold. If the issue progresses, fuel economy will decrease, and black smoke may appear from the exhaust due to incomplete combustion. Continued operation with faulty injectors can lead to increased engine wear and potential damage to other fuel system components.

Installation Tip

Ensure the injector bore in the cylinder head is clean and free from carbon deposits before installation. Avoid lubricating the injector seal excessively, as this can affect seating and sealing.

Service Note

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