    BM6A

    The NGK web site says that the 5921 (removeable terminal nut) BM6A have been discontinued,
    and to substitute with NGK 7421 BMR6A Nickel Spark Plug (also with the removeable terminal nut),
    but I have no idea if the length changed, so I found some of the old BM6A’s on Ebay.

    Prepare to be boarded!
