Good To Know

Q: What are the signs of a failing fuel injector? A: Rough idle, misfires, hard starting, and reduced power are typical symptoms. A clogged or failed injector cannot deliver the fuel volume the engine needs.

Q: Can I replace just one injector? A: Yes, replacing only the faulty unit is fine if the others are in good condition. On high-hour engines, replacing the set keeps fueling balanced.

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