I used this on my Holley Sniper EFI system after experiencing a creepy loud whistle when opening the throttle about 30%. This gasket not only eliminated the whistle, but also made the throttle body cooler than before; which is very important for the Sniper system as the ECU is part of the throttle body. Also, the holes are 1 3/4 inches, which means the gasket doesn't obstruct the throttle bodies and airflow. I previously tried the Mr Gasket 758 gasket and it started falling right out of the packaging and holes. were smaller than the throttle body holes. I threw Herr's poetry in the trash and ordered this.
