i just got my plugs(NGK) in from clubplug.net and they didn't come with those washers/gasket. i don't remember if my other NGKs did. So do the NGK Tr6 plugs come with the washers or not?
Also i think these plugs are from canada and the stock number is differant than the one on NGK's webpage. Does the stock number matter at all?
