    Hi Guys,
    I currently run an NGK B9ES spark plug, it has the 13/16 hex.
    Is there a similar plug NGK or other wise that has the 5/8 hex?

    Thanks in advance.

    NGK R5671A-9 is the same as the B9ES but has a 5/8 hex.

    Is 6061 the one to replace the B9ES?
    Is that what most guys run and why?

    6061 is a 13/16 hex and he was asking for a 5/8 hex. The only advantage to a 6061 is a shorter ground strap.
