Trans-Dapt 2529 Swirl-Torque Carburetor Spacer, 1-Inch Thick, 4-Hole Square Bore with PCV Port

Improve carburetor performance and airflow with the Trans-Dapt 2529 Swirl-Torque carburetor spacer. Designed for square-bore applications, this 1-inch-thick spacer helps increase plenum volume and promote smoother air and fuel distribution between the carburetor and intake manifold. Its four-hole design supports consistent flow while maintaining a practical fit for compatible performance builds.
Constructed from durable phenolic material, the spacer helps reduce heat transfer from the intake manifold to the carburetor. The black finish provides a clean, professional appearance, while the integrated PCV port supports convenient crankcase ventilation routing where applicable. This design is well suited for street performance, custom engine projects, and carbureted applications requiring additional intake spacing.
The Trans-Dapt 2529 includes the gaskets and hardware needed for installation, helping simplify setup and reduce the need for separate components. Verify carburetor pattern, intake manifold compatibility, and PCV requirements before installation. With its square-bore configuration, phenolic construction, and Swirl-Torque design, this carburetor spacer provides a practical upgrade for improving intake system function.
