MagnaFuel Anti-Reversion Spacer Plates

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. These spacer plates 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 or drip down carburetor bores. Anti-Reversion plates seal with additional gaskets that help isolate vibration and help prevent fuel cavitation.
