The Edelbrock 1-inch open-hole carburetor spacer #8710 is a black phenolic plastic spacer used to add plenum volume or increase carb-to-plenum floor distance. At one inch thick, the phenolic construction offers heat insulating properties to reduce heat transfer to the carburetor, aiding in improved throttle response and helping preserve consistent fuel metering under varied thermal conditions.
