Anti-Reversion Plate, 4-Hole, Square Bore Pattern, Each

Custom-machined MagnaFuel anti-reversion plates keep your carburetor flowing at or beyond its cfm rating by reducing intake reversion at higher rpm. They do this by redirecting the hot gases that can rise into the intake manifold as the intake valve opens and the exhaust valve is still closing. This helps release and atomize fuel droplets that sometimes stick and drip down the carburetor bores. MagnaFuel's anti-reversion plates are machined from billet aluminum and coated in their popular purple anodized finish. If you're running aggressive camshaft profiles, then you'll need MagnaFuel anti-reversion plates to eliminate the hot gases and increase fuel atomization.
