Specs At A Glance

Good To Know

Q: Do I need to replace all injectors at once? A: It is often recommended to replace injectors as a set on high-mileage engines for balanced fuel delivery. A single replacement is acceptable if the others test within spec.

Q: Is fuel system cleaner enough to fix a clogged injector? A: Cleaner can help mild deposits but will not repair a failed solenoid or worn nozzle. A faulty injector should be replaced outright.

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