This is a high-pressure fuel injector designed to precisely meter and atomize fuel into the engine's combustion chamber for optimal power and efficiency. Manufactured to exact specifications, it ensures consistent fuel delivery and spray patterns superior to a worn or clogged injector. Operators may notice rough engine running, a significant loss of power, or excessive black smoke from the exhaust when this injector begins to fail.

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

The first sign of a failing injector is often an uneven engine idle and a noticeable reduction in overall power. If ignored, the issue can progress to misfires, increased fuel consumption, and potential damage to the piston and cylinder walls from unburnt fuel. Continued operation risks severe engine damage and costly repairs.

Installation Tip

Ensure the injector bore in the cylinder head is perfectly clean and free of any carbon deposits before installing the new injector. Never lubricate the injector body excessively, as this can affect seating.

Service Note

Inspect the fuel rail pressure and the condition of the fuel filter when replacing a fuel injector.
