Phenolic Carburetor Spacers
B&B offers new pressure molded Phenolic Carburetor Spacers which allow racers to tune their engines induction systems for optimum performance. They increase the manifold plenum area and provide the maximum thermo barrier between the manifold and carburetor. Carburetor spacers will often solve reversion problems encountered when using single plane intake manifolds. Both gasket surfaces are double-disc ground to insure a positive seal.
