I can't answer that but you better state gas or alky to get a better answer!

I wouldn't put a champion in the lawn mower. :-)

Use NGK R5673-8 gapped on .040 with MSD 6AL

Perfcon, not wanting to hijack the thread, but on the same note, what Plugs would you recomend for a set of Brownfield 23 degree Aluminium on Alcohol?

Brodix says use one heat range colder for alcohol.A number 7 NGK but number 8's will work.
