plugs for 0470

[djbeagle]

I am in the process of puttig together a new boat. Power plant will be an 0470 with dual ignition. One ignition will be mag and the other will be electronic. Fuel used will be auto not avgas. My question is what plugs to use? The holes are 14mm. Any help or suggestions, thanks!

That's a question for someone like Jr Jurnigan there.

Ultimately may take you some experimentation to find the exact combo to go with
