i found a used parts site that sells the 2.4 intake manifold for cheap (as low as $60) but im assuming it doesnt come with gaskets or any of that. i know i need the four rubber gaskets that go in the air channels but can't find them anywhere. what else do i need? (i'm swapping the 2.4 IM to an 05 2.2) maybe the throttle body later but someone told me you need tuning (for the TB not the manifold), anyone know? thanks and sorry if this has been asked 50 times.
