X AUTOHAUX Universal Vacuum Manifold Block — 5×1/8" Ports, 2×1/2" Inlets, CNC Billet Aluminum

Compact billet vacuum manifold that provides five 1/8" vacuum ports and two 1/2" interfaces for clean, reliable boost and vacuum distribution in cars, bikes, or boats.

This CNC-machined X AUTOHAUX vacuum manifold is a universal add-on designed to centralize vacuum and boost lines for tuners, wastegates, gauges, and boost controllers. Built from corrosion-resistant billet aluminum, it replaces messy hose junctions with a compact block that includes plugs and mounting hardware so you can route multiple devices from a single intake or boost source.

How does this manifold simplify vacuum and boost plumbing?

Instead of running separate lines from the intake or turbo housing, the manifold consolidates sources into one neat block. You attach a primary inlet at the 1/2" interface and distribute to up to five 1/8" ports, keeping lines organized and easier to service.

• Five 1/8" ports accept gauges, controllers, and sensors.
• Two 1/2" interfaces for main vacuum/boost connections.
• Includes threaded plugs for unused ports to prevent leaks.

Will it fit my vehicle and common aftermarket components?

The manifold is engineered as a universal unit to work across many motorcycles, cars, and boats that use NPT fittings. With standard 1/8" and 1/2" NPT sizes, it pairs with most boost controllers, vacuum gauges, wastegates, and sensor lines without the need for exotic adapters.

• Universal NPT thread sizes for broad compatibility.
• Adapters available if your application uses different thread types.
• Compact profile fits tight engine bays where space is limited.

What materials and hardware are included, and how durable is it?

The block is crafted from CNC-machined billet aluminum for strength and corrosion resistance under heat and vibration. The kit ships with plugs, brass nuts, screws, and mounting hardware so you can install it right away and expect long service life in harsh under-hood conditions.

• CNC billet aluminum resists rust, peeling, and corrosion.
• Brass nuts and screws included for secure connections.
• Plugs for unused 1/8" ports to maintain airtight operation.

How do I install and where should I mount it for best results?

Mount the manifold near the intake or turbo boost source using the provided screws and nuts, then route hoses from the 1/2" inlet to the source and from the 1/8" ports to your devices. Choose a location that minimizes long hose runs and avoids excessive heat exposure from exhaust components.

• Mount using supplied screws and nuts for a secure fit.
• Position close to the boost/vacuum source to reduce line length.
• Keep hoses away from hot exhaust sections; use heat shielding if necessary.

Who is this for: Tuners, hobbyists, and technicians who need a tidy, reliable way to split a single vacuum or boost source to multiple devices will find this manifold useful. It's aimed at anyone adding boost controllers, wastegates, gauges, or sensors to performance engines on cars, motorcycles, or marine craft who wants durable hardware and straightforward installation without custom plumbing.
