Edelbrock Carburetor Spacer - Open 2" Spacer - Black Phenolic Plastic 1311114 Reduces friction and dragUse open spacers where more plenum volume or more carb to plenum floor distance is required. 4 hole spacers enhance low rpm torque and throttle response and dampen reversion effects on the carb. The superior heat insulating properties of wood fiber laminate are ideal for reducing heat transfer to the carb. 8713, Edelbrock, Spacer, adapter, Carb adapter, Carburetor adapter, standard flange, square Bore. 4 barrel, 4 hole spacer, 4 hole, intake manifold,
