Emissions

This part is legal for sale or use on Emissions Controlled Vehicles, Uncontrolled (Non-Emissions Controlled) Vehicles, and Racing Use Only Vehicles because it does not affect vehicle emissions and is not covered by emissions regulations.

See Emissions Details
Why use a power valve block off? If you have a dedicated race engine that never sees part throttle, but goes right from idle to full throttle you may see more consistency. The block off screws right in place of the existing power valve. Includes gasket.

Features:

  • Can offer more consistency on racing engines
  • Screws right in place of Holley power valve
  • Gasket included
