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 initially cause noticeable engine misfires or a rough idle. If ignored, fuel delivery can become inconsistent, leading to reduced power and increased fuel consumption. Continued operation with faulty injectors can result in uneven cylinder wear and potential damage to other engine components.

Installation Tip

Ensure the injector bore is meticulously clean before installing the new injector to prevent leaks and ensure proper seating. Do not reuse old copper washers or seals; always use new ones.

Service Note

Inspect the fuel lines, fuel filter, and engine control module for any related issues, and consider replacing the injector seals and O-rings.
