Good To Know

Q: How many injectors does my engine need? A: The 1503 engine uses multiple injectors, so confirm the quantity required for your model before ordering. Each listing is for one injector unless stated otherwise.

Q: Should I replace all injectors at once? A: Replacing the full set together can keep fuel delivery balanced across cylinders. Check the condition of the others during the job.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
