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, especially at idle, and can lead to a noticeable loss of power. If left unaddressed, continued improper fuel delivery can result in increased fuel consumption and potential damage to other engine components due to incomplete combustion.

Installation Tip

Ensure the injector bore is clean and free of debris before installation to prevent leaks and ensure proper sealing. Avoid overtightening the injector hold-down clamp, as this can damage the injector body or the cylinder head.

Service Note

Always replace the fuel filter and inspect fuel lines for any signs of damage or contamination when servicing fuel injectors.
