Specs At A Glance

Good To Know

Q: How many injectors does a 1503 engine use? A: The 1503 platform typically runs one injector per cylinder, so confirm your model's count before ordering. Replacing all of them at once often makes sense during a full service.

Q: Do I need to reprogram anything after installing a new injector? A: In most cases no reprogramming is needed, but fuel trims should settle after a short run. If codes persist, have the fuel system pressure checked.

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