Just arrived, 4 CR8EIX Iridium plugs for $7.40 each, free shipping, no tax from Amazon. Had 44,000 on my old Iridiums, they looked as good as new but Ionbeam said if I examined them under an electron microscope I would see that a few molecules of Iridium would be worn away. Since the tank was off anyway (quit laughing!!), I thought I would routinely change them.
