The Trans-Dapt 1/2 inch x 5 1/8 inch Air Cleaner Spacer (Model 2378) is a precision carburetor spacer designed to elevate your air cleaner assembly above the carb flange, creating essential clearance for intake manifold modifications and accessory installations. This 0.5-inch-thick spacer is engineered for engines running traditional 5-1/8-inch carb flanges and addresses a common challenge in small-block engine builds: accommodating upgraded intake manifolds, fuel injection conversions, or custom air intake systems without mechanical interference.

Constructed from black plastic, the spacer provides reliable durability across typical engine bay temperature ranges while remaining lightweight. The 5-1/8-inch carb flange dimension ensures compatibility with standard carburetor mounting patterns found on small-block Chevrolet, Ford, and Mopar platforms. Installation is straightforward: the spacer sandwiches between the carburetor and the air cleaner base, requiring no additional machining or specialized tools. Its 0.5-inch thickness delivers the precise vertical offset needed to clear most performance intake systems without sacrificing air cleaner seal integrity or drawing hot engine bay air.

This product is essential for hot rodders, restoration enthusiasts, and engine builders upgrading carburetor-fed engines with modern intake technology. Whether you're installing an aluminum dual-plane manifold, integrating a cold-air intake system, or accommodating a fuel-injection retrofit, the Trans-Dapt spacer solves the common geometry conflict between tall air cleaner assemblies and modified intake components. Ordering this spacer eliminates costly trial-and-error fitting and ensures your air cleaner assembly seats properly while maintaining optimal engine performance and cooling airflow.
