Great Onan Performance
The Spark Plug worked perfectly for my Onan RV generator. After installing it, the generator started up smoothly and ran reliably without any issues. It’s a high-quality replacement that restored my generator’s performance, and I’m very pleased with the results. Definitely recommend it for anyone needing a spark plug replacement for their Onan generator!

Great item!
The only thing you need to know about this spark plug is that you need to set the gap for the specs on your generator! I set the gap, installed it, & my generator fired right up & is running fine!

Plug is a Champion RN14YC
The plug is fine, but I thought I would get a spark plug that indicated Onan 1670275 on the plug. In reality I was sent a Champion RN14YC. So, I paid $15 bucks for a spark plug that I thought would be Onan. I could have bought three Champion RN14YC plugs for the same price. Do yourself a favor and just purchase the Champion RN14YC and save yourself some money.

Great plug
Purchased this plug to use for my Onan 4K Generator. It fit perfectly and was gap'd at exactly the right .025 gap. Didn't have to do anything but take the old one out and put the new one in. Done.
