I was helping a friend take apart an old rusty model A and the engine had "Wizard" spark plugs (they look as old as the car). What's the history on those? Just wondering.
Thanks for your time.

Don't know the history but when I got my 28 chrysler to restore there were 4 in it, and to my suprise they look like the spitfire plug with the duel electro, so I figure the duel electro isn;t new! I still have them and did use them for awhile till I got new one to put into my rebuilt engine. It looks to me that everything repeats its self.
