Manifold Spacers are Snake Oil on an NA Engine because they are under suction pulling air in. NA engines suffer because of the laminar flow of air making turns and bends on the way in and from friction across the surfaces. You flip that when you boost an engine and now the intake manifold is under pressure. Air is pushed or squeezed past all of those surfaces and needs a place to go rather than being cajoled into the manifold.I thought the same about manifold spacers.
