HolleyDAYS are here again! SAVE up to 20% on this part and hundreds of other Holley brands during the 2018 HolleyDAYS sale 11/15/18-12/31/18.

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.

  • Direct Replacement For OE Units
  • 2 in. Throttle Bore
  • 42% Area Increase Over Stock TBI
  • Including Air Distribution Ring
  • Increased Torque and Horsepower up to 25%
  • 50 State Legal

Installation Instructions (PDF)

Some parts are not legal for use in California or other states with similar laws/regulations
