Specs At A Glance

Good To Know

Q: How do I know my injector needs replacing? A: Rough idle, hard starting, misfire codes, or a noticeable loss of power on a 1503 engine often point to a dirty or failed injector, so testing or cleaning before replacement is worthwhile.

Q: Can I replace just one injector? A: Yes, but many owners service all of them at once so flow rates stay balanced across the cylinders and future repeat labor is avoided.

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