Edelbrock 1/2" Divided Spacer, Wood Fiber Laminate

4-BARRELL CARBURETOR SPACERS 
Use 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.
