Specs At A Glance

Good To Know

Q: How do I know my injector needs replacing? A: Rough idle, misfires, hard starting, and poor fuel economy are common symptoms of a clogged or failed fuel injector. A noid light or resistance test can confirm the injector is not firing.

Q: Do I need to replace all the injectors at once? A: Not necessarily, but replacing them as a set keeps fuel delivery balanced across all cylinders. If one injector failed from contamination, inspecting the others is worth the effort.

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