Good To Know

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

Q: Should injectors be replaced as a set? A: Many technicians replace all injectors at once when one fails so fuel delivery stays balanced. Check your service manual for the recommended approach.

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