Skunk2’s 1-liter Ultra Race plenum spacer increases inlet plenum volume for Ultra Series Race intake manifolds used on B- and K-series Honda/Acura engines. The billet aluminum spacer includes gaskets and fasteners for direct installation with the Ultra Race manifold, allowing a modest increase in volume without modifying the manifold. It’s a compact upgrade for track-focused Ultra Series applications.
