Holley designed these throttle bodies with all relevant emission provisions and hook-ups for a true 50-state legal installation. They are engineered for a bolt-on installation on stock factory Manifolds for the applications cataloged. The one-barrel throttle bodies have been assigned to the California Air Resources Board (C.A.R.B.) Executive Order (E.O.) number D??"115??"4. The two-barrel throttle replacement bodies are considered to be the functional equivalent of the original equipment throttle body and, as such, are considered to be 50??"State legal.
