Spoon Sports Ventuli Plate
From the Spoon Sports Catalog:
"Racing engines are machined with extreme precision and feature filled-in intake ports. This is done to make use of the venturi effect a fundamental of fluid mechanics. Specifically, by smoothing a portion of the intake port and making it narrower, it is possible to increase the speed of the air-fuel mixture. By simply inserting this component between the cylinder head and the intake manifold, it is possible to obtain the optimum port shape for the above mentioned venturi effect. When the speed of the air-fuel mixture is increased in this way, the efficiency of combustion inside the engine is improved and power increases accordingly."
This innovative item replaces the factory intake manifold gasket. Its unique design takes advantage of the venturi effect, giving a more streamlined airflow into the combustion chamber. Results have varied between 6-8 HP increase in the mid RPM and slightly improves torque.
