The Edelbrock Performer 1/2-inch divided-wall spacer is a 1/2" aluminum spacer intended for two-plane intake manifolds. Its divided-wall design increases carb-to-plenum distance while helping to dampen reversion effects, improving low-speed torque and throttle response on compatible Performer/4500-style applications. Use it to fine-tune intake geometry without major manifold changes.
