## Questions & Answers

**Q: why does information refer to this as a glow plug?  I associate glow plug with diesel and this is for RV gas generator.**
A: I don’t know why it says what you wrote.  I have bought replacement spark plugs and air cleaner directly from Onan.  So far I have replaced these items together twice.  Every other year.

**Q: Is this plug good for the propane models?**
A: Yes, it works with the propane models.

**Q: Will this work on the onan ky 4w 4000?**
A: Yes, but do yourself a favor and go to the ngk website and find the corresponding ngk plug. The plug you're looking at now is an overpriced champion plug. Not kidding. If you order this you will get a $2 champion plug in an onan box.

**Q: Will this work on my onan 6.3 nhefa26110p propane generator**
A: check your manual or with Cummins.
