Radioactive Spark Plugs!

[MikeK]

I picked these up (carefully with gloves! ) at a swap. 7/8 thread, they fit a Model A.
...........Anybody ever use them? .........Any idea as to the heat range?

You need a hot motor to run these!!!

Since the half life is 138 days- Me thinks they have lost their zest.

Pretty cool none the less!

There's some information here: http://www.blackcatsystems.com/science/radprod.html about those. Not a lot of detail, and I'm not sure why they thought it was going to help the spark bridge a larger gap... but "radioactive" was a buzz word much overused back in the day, much like "antioxidant" today

I think those are very cool, I wouldn't put them in the car, id keep them box and all as a collectable.

I have some of those of various sizes, they stay in the boxes because the ceramic is a pink-purplish color that clashes with Ford Green...

However I have one in a recently acquired engine that runs fine; it has a different spark plug in every cylinder (which I don't recommend) but they all seem to be in the correct heat range.

Pink? Interesting; I recall the only pink plugs I have seem were "Lodge".

You really need to find a RYAN spark plug, neat logo with a monoplane flying at you. Sold mine a few years befor joining the HAMB Sorry.

OK, I have to have one of those boxes...

I have a box of these that are T-30, The thread dia. looks about 3/8". I think they fit a 216 c.i. chevy. Does yours have a date on the inside of the top? Mine has Oct.23 1941. I had forgot I even had them. Thanks for reminding me. "COOL"

So you're saying they're dilithium-powered flux capacitors?

The Atomic Four really took Champion RJ12C's.

I bought a box of those many years ago and have run them in my Coupe ever since. I really didn't believe the advertising. It would be interesting to check them out.
