Back in the day, there were spark plugs that could be taken apart for cleaning and to remove the carbon. I think this is such a set of spark plugs. IT looks to me like there are two places you can put a wrench to take the bottom of the spark plug apart. Wizard is Western Auto's house brand, if that was part of your question.

I made the "Wizard" connection, but was just confused about not seeing any "threads"? The bottoms just look like long chutes. Electrodes inside?

Weird.

It looks to me like there is a slip over cover on the bottom protecting the threads.
