Yea, a lot of Motorcraft stuff is made in Mexico, Autolite in China, etc. Never had any problems with any of eithers plugs though!

And this is so sad....yrs ago I orderd some Shelby mustang stuff from a mustang parts place,some came in a ford marked and Shelby marked box,but the parts had a small sticker stateing made in mexico,or tiwan or any other place but in the USA....pop

does any of the new plugs come with a gasket or alu.shim? i noticed on the champion plugs i just took out that they had been leaking because i saw a little oily substance on the threads and above the threads on nearly every plug!! i remember when plugs came with a shim. plugs dont seal good on my heads without shims

Tapered plug seats ,require a tapered plug,,if not the plug needs a washer,like on a champion plug that goes in your lawnmower...pop
