6-Port Vacuum Boost Dist

The 6-Port Vacuum Boost Distributor from ICT Billet is a precision vacuum manifold engineered for automotive builders and mechanics seeking reliable vacuum distribution across modern and classic engine configurations. This aluminum component consolidates multiple vacuum line connections into a single, compact hub, eliminating the clutter of individual vacuum ports on boost controllers, emission systems, and brake boosters. Whether you're tuning a turbocharged engine, upgrading a carburetor setup, or integrating aftermarket vacuum-dependent devices, the 6-Port Vacuum Boost Distributor simplifies plumbing and reduces leak points in your fuel or air induction system.

Constructed from lightweight aluminum in natural finish, this manifold features two 1/4-inch NPT ports and four 1/8-inch NPT ports, delivering flexible connection options for both primary vacuum sources and secondary distribution lines. The dual-size port configuration allows you to prioritize critical vacuum circuits—such as brake booster or distributor advance lines—through the larger 1/4-inch inlets while routing secondary applications like emission control or boost reference sensors through the 1/8-inch ports. NPT (National Pipe Thread) fittings ensure positive sealing without requiring additional adapters, and the compact 2.45 x 2.15 x 6.95-inch footprint integrates seamlessly into tight engine bays without sacrificing accessibility for future service.

Professional engine builders and street-car enthusiasts benefit most from this manifold when assembling fuel-injected conversions, turbo upgrades, or restomods where multiple vacuum consumers demand clean, reliable distribution. It pairs exceptionally well with vacuum-operated boost controllers, fuel pressure regulators, and advanced ignition systems that require isolated vacuum references. Installation requires only standard NPT wrenches and silicone or rubber vacuum hose—a straightforward upgrade that pays dividends in reliability and layout cleanliness. This is an essential component for any serious engine modification or performance tuning project where vacuum line organization directly impacts both safety and drivability.
