86-92 SBC Ported Throttle Body Spacer

The 86-92 SBC Ported Throttle Body Spacer from TRANS-DAPT is a precision intake manifold component designed specifically for small-block Chevrolet engines. This product is ideal for automotive enthusiasts and performance-focused mechanics looking to enhance airflow dynamics and thermal management in their vehicles. By fitting between the throttle body and intake manifold, it serves as both a structural adapter and an air-passage optimizer.

Engineered to improve volumetric efficiency, idle quality, and mid-range throttle response, the ported design of this spacer effectively removes restrictive casting edges and sharp transitions. This reduction in turbulence promotes laminar airflow from the throttle body into the manifold plenum, enhancing overall engine performance. The spacer is designed to match OEM throttle body and manifold bolt patterns while optimizing internal passage geometry.

This throttle body spacer is particularly beneficial for street engines and restorations where intake manifold port matching is critical for baseline performance. Its compact profile ensures a clean underhood fitment without clearance conflicts on carbureted or fuel-injected platforms. Installation is straightforward—simply sandwich it between your existing throttle body and intake manifold, and torque to factory specifications.
