Cub Cadet Spark Plugs

[Pochie]

I have a 1991 Cub Cadet. It has the Kohler 17 hp engine. I currently have Champion RC17YC plugs that I put in in 2006. I have checked many spark plugs sites and none can give me a conversion for other plugs, including Champion. She runs well, I just thought I'd put some new ones in. Any help is appreciated. Thanks, Pochie

If you go to your local parts house they will be happy to convert for you

What is the name and model # for that engine? It seems to me you could use an RC14YC plug, but it might not be hot enough.
