You can buy new X's for about $20 each at O'Reilly, or $5 - $10 used at swap meets if you're not in a hurry. They also turn up on eBay.

I haven't bought any other kind, so somebody else will have to tell you about those.

Steve, Do you have an O-Reilly part # I can not find any parts house in my area that can get any 1/2 inch pipe thread plugs of any brand or #.

You didn't reveal what car you need pugs for, but if you're being "correct" you should be aware that X plugs are not all the same.


On the left is the type of X used up until about 1920 or 1921. It has no ribs on the insulator. The center plug is identical except for the ribs and the printing. Both have the fully removable electrode with 5-40 thread. The center plug was used briefly in the early twenties. This was the peak period of Model T production, so there are a lot of these around. The third is the most plentiful, being used from the early-to-mid-twenties until now. The electrode has an 8-32 thread and is not removable, held in by a crimped brass cap. I wish I could be more definite about the dates, but so far I haven't found much information on that beyond advertising illustrations. In my limited experience they all work equally well.


Here are the two basic types disassembled to show the parts. The bottom plug is a new one from current production.

Also search these on Amazon as the price is lower sometimes. I saw some on sale for just over $17 not to long ago.....

I love these original old X plugs and use them (they are a fun little project to clean and rehabilitate), but also keep in mind that there were many, many other brands of similar take apart plugs available in the day and are nearly as easy to find as champ X plugs. Most work very well as they were designed for the model T.

I am currently running some NOS Edison albanite plugs, running just as well as the X plugs did.

I ran across some Champion 3X plugs. Look very similar to an X but have a different thread. Package said for A or B. Anyone know what that thread size might be.

Tom,

3X plugs fit many cars including Model A / Model B Ford.

You shouldn't have a problem with the Edison #14 Spark plugs...... good performer.

Ran the same the last 4 years with them

I am running a set of old used Wards. I cleaned them the other day just because I had em out, really didn't need to. Even pumping a little oil they looked good. Of course it could be that new carb I am playing with! :-)

Many examples of T plug options here.

I just checked the link that Steve posted. They are $21.49 at O'Reilly. I've been running AC #26s for years, and they are really good plugs. The trouble is, they are no longer being made.

That price (and even more from Model T parts dealers) is why I use old ones bought cheap at swap meets. They work fine for me.
