I was hoping someone with better wisdom than I can identify if these spark plugs are applicable to either the model T or A.
Reason: I located the spark plugs at a farm tool shed. On this farm there is a model T oxidizing in the woods along with other hit-miss engines on the farm. Any help would be highly appreciated with identifying these spark plugs for the correct application(s).
That Edison plug is missing the copper gasket above the threads..... May be for a Model A.
The Edison plug for Model T's is their #14 plug.
Have a set in my '26, runs better, IMHO, than the Champion X's
..... also installed a set in the 1922 Touring that belonged to Thomas A. Edison himself at his Glenmont estate in West Orange... along with some other maintenance two years ago. Sadly, the good running car is now a part of a static display in the estate garage.
Found picture originally posted by a Forum member of the Edison # 14 spark plugs.
I concur with Bob. I run the Edison plugs that he shows in the picture above. They run great!
: ^ )
The pictured plugs are now in the 1922 Edison Model T Touring at West Orange.
The ones in my car came from a well respected spark plug collector
Plugs in the '26
Here is another type of Edison. I have not tried these. I have used the 14's in a standard T head and the X-46's in a Roof overhead and all worked well. In 40,000 or 50,000 miles of touring, I have only had problems with the new Autolite plugs and considering their price, that's not all that bad.
Interesting they are EDISON-SPLITDORF. I don't know the history.
Then there are these with the red script. I don't see a number except a 32 stamped in the hex.
Rick, As you see in Bob's photo, the Model T used plugs with a conical thread. If you can get a few photos of the T in the woods, I and probably more of us here would love to see it

I see a serpentine belt on your engine. Am I correct. That's all I use now.
Your eyes do not deceive you. Purchased locally.
Also is the "Z" head, '11 factory numbered aluminum intake, straight thru NH carb, aftermarket heat pipe..... and something you cannot see, because it's hidden in a Ford commutator.... the E-Timer Ignition system.
oops... forgot the Becker 6 volt alternator.
Model T plugs do not use a copper gasket. They are pipe threads.
Larry, the plug Rick questioned needs a gasket. That plug is not used in a standard Model T cylinder head.
Forgive me Autolite!!! The plugs that failed for me were Motorcraft. I mis-spoke.
I appreciate the comments so far. It seems to be a rather firm agreement that the X-46 Edison Albanite spark plug more than likely does not fit the model T. I'll be sure to get some pictures of what is left of the Ford in the woods as it is best scene when winter sets in with all the underbrush that covers the body. As far as I can tell all that is left is the body. I did not see any chassis on the vehicle unless it is covered by earth.
Again, I appreciate the this forum and the people that love their Model T(s).
I have a Edison spark plug cross reference sheet somewhere.... will post application for your X-46 plug later.
