1in Phenolic Carb Spacer Swirl Torque w/PCV

The TRANS-DAPT 1 inch Phenolic Carb Spacer with Swirl-Torque and PCV is a precision intake manifold riser designed to optimize air distribution and engine performance on carburetor-equipped vehicles. This aftermarket spacer addresses a critical gap between your carburetor and intake manifold, improving fuel atomization and throttle response while maintaining OEM compatibility. It is particularly beneficial for those tuning classic muscle cars, street rods, or vintage trucks.

Constructed from phenolic composite material, this spacer provides superior insulating properties compared to aluminum alternatives, reducing heat transfer from the intake manifold to the carburetor bowl and promoting more consistent fuel vaporization. The integrated Swirl-Torque design creates a controlled vortex pattern in the intake tract, enhancing air-fuel mixing efficiency and combustion uniformity across all cylinders. The one-inch thickness offers a balance between manifold separation and installation clearance, while the integrated PCV passage maintains proper crankcase ventilation.

This spacer is particularly suited for carbureted V8 engines and four-barrel applications, where intake temperature control and fuel distribution consistency can enhance driveability and efficiency. However, it is important to verify compatibility with specific carbureted setups to ensure optimal performance. Installation is straightforward, making it a practical choice for enthusiasts looking to improve their vehicle's performance.
