The Densos I use are a copper electrode type. The advantage over your 'triple-sparker', platinum, iridium, depleted plutonium [whatever] plugs is that you can't touch them up with an ignition file like you can with copper plugs. The fancy plugs will lose their fancy plating, and who knows what the base metal is?
This is vintage technology. Stay within the vintage parameters.

Also don't leave the ignition key on long w/o running with the Ignitor I. It will burn out. Ignitor II's solved this gripe. [But mine burned out after 7 years in the AZ desert.]
