9137 - PBM Performance - 2" Plastic Carb Spacer - 4150 Open Plenum

Part #PBM9137
A carburetor spacer increases the intake plenum volume by creating a taller neck on the manifold. With the extra volume, the distance between the plenum floor and the bottom of the carburetor is also increased. The extra distance helps the fuel/air mixture to remain more consistent. Along with the extra plenum volume, the intake runner volume is also increased, potentially allowing the engine to breathe more efficiently and ultimately make more power.
