Bowers spark plugs

Post by Retro54 » Sun Apr 21, 2019 7:55 pm

My recently acquired 15 T with 22 engine has Champion X's in the engine, but in the parts boxes that came with the car had four of these 'Bowers Ceramite Sealed' spark plugs. Plugs are # 12-H's and appear to be new in box.

My dad and brother run the champion X's in theirs and I'll probably do the same, but was wondering if anyone uses or has used Bowers plugs. And/or does anyone know if the 12-H size was for use in a T engine? We will of course thread in lightly and turn it gingerly over to check clearances before running them, but always fun to have some first hand knowledge

In any event, enjoy the photos and box art on some vintage plugs!

Thank you in advance for your thoughts and opinions.

Andy B.

It looks like the standard ½" pipe thread for Model T (hard to be sure from the picture). If it is, you can try them and see if they work. Some old plugs are good to go, but others seem to have expired with age. If you don't have a tester, putting them in the car is the only test I know.
The inevitable often happens.

I immediately thought of my Bowes plugs when I saw your Bowers. So many brands. I would think they all should work well in a stock T. The longevity may vary.

When did I do that?
