    5/8 or 13/16 spark plug hex size. Is there any advantage for one or the other.

    No, some motors the 13/16 will not fit. The working part of the plug is the same

    I know the working part is the same, but is having a larger hex better because there is more surface area on the clamping portion?

    I was wanting to use the BR10ES plugs in BAE 8x heads.
