I just contacted NGK. If anybody is looking for the crushable spark plug washers for the NGK CR9EB spark plugs you can find them here. https://www.sparkplugs.com/Champion-10mm-Crushable-Gasket-p26415.aspx
They are 10 mm in size made by Champion and are $0.25 each plus shipping. I would think the iridium are the same size but you can call NGK at 877-473-6767 to double check. I figured with tech bulletin from Yamaha to fog engines during the season there will be more of us pulling our plugs during the season to perform this function and may want to replace the crushed washer with a new one.
