(w/ the Foster Male)is not aluminum. It's either plated steel, or St St. There isn't a whole lot of thread length on the OEM plug, so watch your fill pressure if you go to an aluminum plug.

I ordered my on 1/15/08, and my guess it is one of the first runs. The barrel bands are also aluminum, not the cast (zinc i bet) one they are now.
Is it 2xxx or 7xxx, will 6061 work for lower pressures?
I'll probably just mod a 2240 end cap.
