The Speedmaster PCE120.1008.01 is a 1-inch tall carburetor spacer precision CNC machined from aluminum, designed to fit 4150 square bore carburetors with a 4-port open design. CNC machining ensures tight tolerances for a leak-free seal and consistent fitment between your carburetor and intake manifold.
This spacer helps improve throttle response and fuel/air mixture characteristics by increasing plenum volume beneath the carburetor. Its 4150 square bore configuration makes it compatible with a wide range of Holley-style and comparable square bore carburetors commonly used in performance street and race applications.
