Specs At A Glance

Good To Know

Q: How many injectors does this engine use? A: The 1503 engine uses one injector per cylinder, so confirm how many your service requires before ordering. Replacing all of them together is common when one fails.

Q: Do I need to replace seals when installing this injector? A: New O-rings or seals are recommended any time an injector is removed and refitted to prevent fuel leaks. Inspect the connector and wiring for damage while the injector is out.

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