Looks like like all the ones listed here use a Champion L86C gapped at 0.030.

You should be able to cross-reference that Champion # to any other plug that you prefer. Bosch, NGK, etc.

I can't remember exactly, but I think the manual for mine specified an NGK B5 HS, or B6 HS. But check that against the champion number.
