Edelbrock Performer 1/2-Inch Spacer

This is the Edelbrock Performer 1/2-inch divided carburetor spacer, part number 8715. It's designed specifically for use with dual-plane intake manifolds to help manage airflow and prevent reversion issues from affecting your carburetor. Made from aluminum, this spacer adds a bit of height and volume between your carburetor and the intake manifold.

The divided design is key here. It helps to keep the intake runners separated, which can be beneficial for maintaining proper fuel distribution and preventing unwanted air pulses from the intake from disturbing the fuel mixture in the carburetor. This can lead to a more consistent engine operation, especially under load. It also helps to dampen reversion effects, which are essentially exhaust pulses that can travel back up into the intake manifold and disrupt the carburetor's function.

While this spacer is a straightforward addition, remember it's not CARB approved and cannot be shipped to California. It's a well-built component from Edelbrock that can offer a noticeable improvement in how your carburetor performs with a dual-plane intake.
