The Edelbrock 1" divided‑wall spacer is a performer‑style aluminum spacer for use with two‑plane intake manifolds. Its divided design helps manage airflow between the carburetor and manifold while also helping to dampen reversion effects on the carburetor; the spacer is offered in thicknesses appropriate to dual‑plane applications where a divided wall is required.
