Yeah, I have a set of Allen sockets. the EZ out has a 3/8" head on it So I put my 10mm allen socket on it backwards, then with a 6pt 10mm socket on a half inch Ratchet, I twisted the allen wrench side. The plug didnt budge!!

Its fuckin crazy!! I've never dealt with a plug so tight. We tried heating it up too!! Plus that freeze spray shit on the plug its self should've contracted the plug enough in the heated aluminum to come out. Still nothing. Might have to be drilled and helicoiled, or drilled, welded machined, and re tapped.
