B & B Performance Engine Intake Manifold Spacer

B & B Performance Engine Intake Manifold Spacers

When it comes to precision-machined performance hardware, few names carry as much credibility in the racing and engine-building community as B & B Performance. Since 1974, B & B Performance Sales has laid the groundwork of quality, commitment, and service for performance builders across the country. With ongoing research and development led by the founder of parent company Stef's Performance Products Inc., B & B has developed several innovative products for the performance engine builder. Their Engine Intake Manifold Spacers are a natural extension of that heritage — purpose-built components that reflect decades of hands-on motorsports experience.

What Intake Manifold Spacers Do

An intake manifold spacer is a precisely machined piece positioned between the intake manifold and the carburetor or throttle body. Installed in place of or alongside the throttle body gasket, a spacer effectively lengthens the intake manifold, creating a small amount of extra space for incoming air. Spacers add volume to the intake plenum and increase the distance of the intake track, which can influence how air-fuel charge behaves before it reaches the cylinders. Another key reason to run a spacer is to insulate the carburetor from intake heat, helping maintain a cooler, denser charge — a meaningful advantage on the strip or the street.

A throttle body spacer fits in between the throttle body and the intake manifold, increasing the distance between the throttle body inlet and the rest of the intake — effectively lengthening the intake manifold since it is positioned after the throttle body. By changing the internal flow characteristics of the intake manifold, the volumetric efficiency of the engine is increased, thus producing more power.
