Vacuum blocks serve as a centralized manifold for distributing vacuum and boost reference signals to multiple engine components. By consolidating connections into a single block, you can clean up vacuum line routing, reduce potential leak points, and maintain consistent signal quality for critical peripherals like blow-off valves, wastegates, fuel pressure regulators, and boost gauges.

Our collection includes blocks in a variety of materials, port counts, and mounting styles to suit different setups. Whether you need a compact block with a few ports for a simple install or a larger manifold with multiple outlets for a complex system, you’ll find options engineered for reliable performance. Many feature durable anodized finishes, precision-machined threads, and include the necessary hardware for straightforward installation.
