In Reply to: "Jet Flame" spark plug posted by chewie on Thursday, November 14, 2002 at 2:01PM :
I donated a set of 'radioactive' spark plugs to an automotive museum about 10 years ago, but I don't remember the brand name. They were supposed to contain some kind of radioactive material that improved the performance of the plugs. These were ones that I had found new in their boxes in a WC-9 ambulance that I bought.
