MagnaFuel Anti-Reversion (Shear) Plates Product images may differ from actual product appearance. Increase Airflow by Extending Carburetor Bore These custom-machined plates keep a carb flowing at or beyond its cfm rating by reducing intake reversion at high RPM. They help redirect hot gases that can rise into the intake manifold as the intake valve opens and the exhaust valve is still closing. The redirected gases can then release and atomize fuel droplets that sometimes stick to & drip down carburetor bores. Additionally, gasketed plates isolate vibration and help prevent fuel cavitation.
