PART #: 502-4

UPC #: 090127108284

Emission Control Number 1


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 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. Therefore, the C.A.R.B. E.O. number is not required.
