What it does

The nozzle is the business end of the injector: it sets the spray pattern and the amount of fuel that reaches the chamber. Worn nozzles dribble instead of atomising, which shows up as smoke, poor mileage and washed cylinder walls. A matched nozzle set restores the spray pattern without replacing whole injectors.
