1In Carb Spacer With PCV Fitting Kit

The 1 inch carb spacer with PCV fitting kit from Racing Power Co-Packaged is designed to enhance the performance of four-barrel carburetors by improving intake manifold airflow and engine breathing characteristics. This spacer is ideal for classic muscle car rebuilds, street performance builds, or enhancing low-end torque response.

By sitting between the carburetor and intake manifold, it creates additional volume for better fuel vapor and air distribution across all cylinders. The integrated PCV fitting kit ensures proper crankcase evacuation, which is essential for preventing oil blow-by and maintaining consistent combustion conditions during high-load operation. Constructed from machined aluminum, this spacer is designed to withstand fuel exposure and thermal cycling.

Engine builders, restoration enthusiasts, and performance tuners will find this carb spacer kit beneficial for optimizing engine performance. Its 1 inch height strikes a balance between manifold plenum volume expansion and hood clearance, making it compatible with most engine bay configurations without requiring custom air cleaner modifications.
