GrimmSpeed Intake Manifold to Head Gasket Pair for Phase 1 Subaru EJ Engines. Pick up a couple pairs of these to match up with your phenolic spacers; comes as a set of 2

Note: The pin holes are deliberately made to be slightly smaller than the guidance pins, use a small socket during Installation to push them onto the pins so that the gasket stays tightly in place as you Install the manifold.
