Good To Know

Q: Can I use these spark plugs in my generator? A: Yes, if your generator requires one of the listed cross-reference part numbers, these plugs are a suitable replacement.

Q: Are these plugs pre-gapped? A: They are pre-gapped at the factory, but we recommend checking the gap with a feeler gauge before installation for optimal performance.

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