So I finally gave up and ordered a spark plug from Polaris for my 2017 Polaris 450 HO because I was not sure what to use. I figured when I got the plug I would cross reference and get an NGK. Polaris sent me an Autolite 5923 which for the life of me I can not cross reference anywhere. Searching this forum I see references to NGK BKR5E, BKR6E or BKR7E. I'm not sure what the differences in these plugs are? I don't mind using the Autolite but I have always used NGKs in my machines. Let me know what you are using and how its working out?
