This Fuel Injector is a precision-engineered component responsible for delivering atomized fuel into the engine cylinders at the correct pressure and timing. It is manufactured to meet strict flow rate and spray pattern specifications, ensuring optimal combustion efficiency and power output, unlike a worn injector that may leak or spray unevenly. Symptoms of a failing injector include rough idling, loss of engine power, increased exhaust smoke, and poor fuel economy.

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

Initial symptoms of a faulty fuel injector often manifest as a noticeable increase in engine vibration or a rougher idle. If left unaddressed, this can progress to significant power loss, excessive black smoke from the exhaust, and potential engine misfires, leading to increased fuel consumption and emissions.

Installation Tip

Ensure the injector bore in the cylinder head is meticulously clean and free of carbon deposits before installation. Avoid using excessive force when seating the injector, as this can damage the sealing surfaces.

Service Note

Inspect the fuel filter and fuel lines for any restrictions or contamination when replacing a fuel injector.
