And it is the only one for sale on ebay, maybe it should be priced higher. I am too pragmatic to spend that money on an old sparkplug, but $100 is not that much money in todays world. People spend almost that much on old used half full cans of Krylon paint, would not surprise me at all if someone buys it, or it just continues to sit there:shrug:DalGal:
Vintage (NLA) sparkplug with neon lamp in the insulator. Pretty hard to find in any condition. Not available through Amazon, Alibaba or other conventional sources.
I have one in the original packaging that IS pristine!
