Edelbrock 1-inch open carburetor spacer (#8720) increases plenum volume and raises the carb-to-plenum floor distance to influence throttle response and intake flow. Made from wood fiber laminate for its heat-insulating properties, it helps reduce heat transfer to the carburetor. Offered in an open 1" thickness, it’s aimed at users wanting added plenum volume and thermal isolation without complex modification.
