Idk what material the OEM gaskets are as I've never had some in my hands. I have some ordered but haven't picked them up yet. For the Intake gasket I'm quoting two guys from ultimatesubaru.org "Subaru's intake gasket is a multiple layer metalic gasket", and "Subaru's OEM intake manifold gasket, just like their headgasket is graphite impregnated metal"
I don't see a purpose for the O-ring when doubling up on gaskets works fine on the injector stacks
Well, we've been waiting this long.... patient is my middle name
