# 0G752239. Optimax 225. 1998. The manual calls for 2 different possibilities. Severe duty NGK PZFR5F-11. Light duty NGK ZFR5F-11. I would assume weekend angler would be light duty. Do they have an updated plug that would be better? This is from 98 manual.

Thanks for the reply. That post is why I ask. It shows a different plug compared to owner's manual and a different gap. I was just wondering if that is an updated plug or what is the reason for difference. Thanks again.
