Injector Nozzle

The injector nozzle controls the precise delivery of fuel into the combustion chamber — a critical component for engine efficiency, emissions, and starting performance. This catalogue covers 6,130 injector nozzles for petrol and diesel engines, fitting passenger cars and light commercial vehicles across a wide range of makes and models.

• Always select by vehicle make, model, year, and engine code — different engine variants of the same model often require different nozzles.
• Cross-reference the OE number to confirm compatibility, especially for older vehicles where production runs may vary.
• Consider brand quality — a worn or leaking injector nozzle leads to higher fuel consumption, rough idle, and potential emissions failures at roadworthiness inspection.
• Note that injector replacement may require diagnostic equipment checks and, on some vehicles, an adaptation procedure.

What are the symptoms of a faulty injector nozzle? Rough idling, increased fuel consumption, misfires, or excessive exhaust smoke may indicate a worn nozzle — however, diagnosis with a scan tool is recommended to confirm the fault.

Can an injector nozzle be cleaned instead of replaced? Professional ultrasonic cleaning is an option for minor deposits, but mechanically damaged or leaking nozzles should be replaced.

How do I confirm injector compatibility? Check the engine code and OE number before ordering — an incorrect nozzle may cause misfires or engine management errors.
