The Edelbrock 1/2-inch open wood-fiber carb spacer increases plenum volume and carb-to-plenum floor distance while offering superior heat insulation from the laminate construction. At 1/2" thick, it reduces heat transfer to the carburetor and is used where additional spacing or an open spacer design is preferred to influence throttle response and manage reversion effects.
