    Hello, does anyone know where I can find a 12mm spark plug spanner tool for my 328 ? I do not have one in my tool kit.
    Thank You

    Sorry, I was going off of a previous post for the spanner. I am looking for a spark plug spanner/socket for my '87 328. Any help would be greatly appreciated. Thank You

    The thread size of the 328 spark plug is 12mm so that might be the source of the confusion. IIRC, the hex drive size is 18mm.
