I just received an order of 4 Iridium spark plugs that came with bare threaded terminals. I'm used to the terminals having cap nuts that pop into the spark plug boots. NGK customer service is sending me some after an email, but mentioned they no longer sell spark plugs with cap nuts and that I need to save mine.
Has anyone experienced this? If so, what is the new standard for a spark plug boot that I need to look for going forward with older Honda's?
