    The threaded portion of the spark plug is referred by the manufactures as “Reach”.
    And the plugs will probably leak without the washer.
    As long as the heat range is correct, the shorter reach plug will probably be okay.
    I’ve noticed the same “shorter” reach plugs at times, and didn’t note
    any problems.
