The Skunk2 1-liter Ultra Race plenum spacer in black adds controlled plenum volume to Ultra Series Race intake manifolds for B- and K-series Honda/Acura engines. Supplied with gaskets and hardware, the billet spacer installs between the manifold and throttle body to alter airflow characteristics while retaining the Ultra Race fitment. It’s intended for race-oriented builds using Skunk2 Ultra components.
