    Original 3X and Plug Box Color Change?

    Does anyone have a picture of an original 3X spark plug box?
    Or, are they identical to the modern 3X box?

    The first box is Champion X, then 3X, then J7J, then J8. I just pulled these pictures from ebay.
    Also, does anyone know when Champion changed box colors, especially from the later blue box to the red box? Thanks

    Doesn't the original 3X have a larger base than the current 3X? Seems like I noticed the vendors sell seperate a different base for 3X judging. Notice the knurl goes all the way up to the hex, the spark plugs they sell have a seperation between the hex and the knurl. Maybe that was when they changed to box color.

      The physical size of the plugs, original and modern are the same. The krurling is different but the size it the same.

      I thought the newer 3X porcelan would not get full points, so why offer new bases for them? Maybe I am wrong. Also the nut on top is wrong. I remember someone referenced a McCaster or Fastenal part number for the nut that looked correct and had the correct threads for the modern 3X plugs. Rod

    I thought they were the same with the red box the X plug and the blue the 3X.

      Question: Why did they take the time and expense to put a knurling on a spark plug to begin with?? When you hand screw one in you usually turn it by the porcelain or the hex portion to get it started.

      Tom i have read a lot of information regarding the plugs themselves but really nothing regarding the boxes. I wonder if champion has some kind of archive research center.

        I tried Google before posting the question, but couldn't find anything about the box colors.
        All the years I worked as a mechanic the boxes were the same as the 4th picture, the red box.
        A few years ago someone posted pictures of how they did the knurling on the base, and it looked perfect.

        Metal rusts and porcelain does not. Find original 3x with rotted metal and replace. Or find the plugs given out at a national meet in the 70's that had the rounded 3 and replace the metal. You can also but the nuts from the vendors. this is from Bratton's, Champion brass top nuts are smaller than the original. Order (17720) for original nuts. And for the large "asbestos" washer, Copper sandwiched with an asbestos substitute is 17730.

          Also look at the knurl to see if the diamond pattern goes inward, or sticks outward as original.

          I'm surprised I couldn't find out about when the color change happened on the last two pictures, even by using Google.

              does a new Champion 3X spark plug need the gap adjusted?
              if so, do you use a file or dremmal tool?

              Thank You;

              There was a recent discussion regarding spark plug length and performance.

              We are not fine point here, and run the Motorcraft TT10 plugs, a known acceptable replacement for the Champion 3X.

              The pix show the length difference between the newly arrived Jordan J-3 plugs and the TT10 plugs. Also shown is the Jordan box..

              3X spark plug question
              by Mike Peters
              I just discovered that all 3x porcelains are NOT created equal. The example on the right just came out of a 28-29 base. As you can see, it is cracked from stem to stern. The porcelain to the left is a spare I've had for years and I thought I would replace the cracked one and end up with a working original 3X sparkplug. Wrong! The good porcelain on the left would not fit into the original 28-9...

              Best Spark plug and Gap
              by A29tudor
              Has anyone come up with a decision what they find for the best spark plug for the Snyder 6.0 head and what gap would seem to be better? Just wondering. I have been using an Autolite 3076 for a number of years (20 +) in a Brumfield 5.9 head, was recommended many years ago by Larry B. I now also have the Snyder 6.0 in other engines and wondered if there are other recommendations.

              by Soapy
              When I was 16, and had a 1930 Tudor, it seemed like it would only run right on the Champion plugs that were available. Over the years, I have been collecting old plugs that would fit. My coupe came with a set of Champion C-4 plugs, which I still have, I have several sets of ribbed Champion W16Y plugs and some singles: A pink Firestone Polonium S-40-CF, A Champion C-4 with a Brass top (with a broken...
