Will work, however outer electrode is not the same and is more prone to fouling. Have you ever wondered why the champion plug has the outer electrode bent up into the plug? Lets the oil drip back into the cylinder to help prevent fouling. I have taken a dremel and reworked the outer electrode and bent it upward, helps. Now I just find old champion X's and rework 'em. That will probably out last you. KGB
Listing was updated to address this concern.
Cool plugs. I've seen many, but never any like those. So pretty they must work well. Most T engines today probably don't pump enough oil into the cylinders to worry about electrode drippage abilities.
Here's what I am running on my car. Same style plug
Wonder what was the function, perceived or otherwise, of the structure at the top?
James, how do they run for you?
Is there a built-in gap inside the little hole on top----to allow spark jump before it gets to electrodes on the bottom?
On a high performance engine they might work. Those are not cool plugs, they are ice-cold plugs. Look where the insulator ends on the center electrode.
I can't really give any insights into performance- when I bought the car these came with it. The previous owner said the car ran fine.
Anyone seen these cheap plugs on Ebay? Claim to be NOS, and maybe if you have a project these could work for you? I have no connection to the sale stuff.

Just found them on Amazon for $16.00 each,
I know a lot of plugs were made back in the T era that were 1/2 in pipe thread, were not all made for the model T. Seems any company who made sparkplugs did make some for Lizzy though.
At least in my cars...nothing seems to work as good as Champion X's.
Amazon is not good for the champion 25s They are $11.50 from Langs and the shipping is less than $8.92
Also, lets not forget that the Champion 25 is not at all the same as a champion X, new or used.
Although there are some old 25s that were a take apart plug that I like better than the current problem prone 25s with the top screw that breaks off.
Link to my page of T era plug info.
I have the best spark plug insurance money can buy: an extra set of real NOS X's on the shelf.
These look like good plugs.......especially at that price.
Seems the new X plugs aren't as good as the old ones.
I don't think ANYONE is manufacturing plugs like the old ones were......
Sounds like you want to buy them. Have at it!
Nice spark plug collection.
Thanks for sharing!
They are not all mine. Some are images I collected from many sources, even from folks here who photograph plugs.
