The engine to stack spacers and the throttle body spacer, have gaskets installed, Sean tells me with a new adheasive.
But the manifold to stack spacers have gaskets that are not attached.
I have confidence in the Outlaw Engineering setup, and am going to use their gaskets.
But, if you prefer you can go with Subaru gaskets.
After all Subaru has the most experiance with Subaru.
