Specs At A Glance

Good To Know

Q: How many injectors does the 1503 engine use? A: The 1503 is a multi-cylinder engine, so it runs one injector per cylinder. Check your craft's cylinder count to order the correct quantity.

Q: Is it wise to replace all injectors together? A: Many technicians swap all injectors at once when one fails so fuel delivery stays balanced. Follow your service manual for the recommended method.

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