Mini Breather Tank 1.50in

The Mini Breather Tank 1.50in from ALLSTAR PERFORMANCE is a compact catch-can system engineered to manage crankcase vapors in forced-induction and naturally aspirated engine builds. This sealed breather tank intercepts oil mist and moisture before they enter your intake system, protecting both engine longevity and air quality. Whether you're running a turbocharged street engine, a supercharged performance build, or a high-revving carbureted application, this tank addresses a critical gap in engine ventilation that many builders overlook.

Designed with a 1.50-inch inlet connection, the Mini Breather Tank features a compact footprint (8.05 x 11.05 inches) that fits tight engine bays without compromising functionality. Its sealed design prevents atmospheric moisture from entering the crankcase while allowing trapped vapors to condense and settle, reducing oil consumption and carbon buildup in combustion chambers. The lightweight construction at 0.55 lbs makes it ideal for weight-conscious builds, while the robust housing handles both positive crankcase ventilation (PCV) and ported breather line applications with equal effectiveness.

Engine builders, tuners, and serious enthusiasts benefit most from this breather tank when upgrading older carbureted engines, modifying PCV systems in late-model vehicles, or integrating custom intake manifolds. The 1.50-inch connection diameter accommodates standard hose fittings, making installation straightforward on most configurations. Regular drain intervals keep the system efficient and extend engine life by preventing blow-by contaminants from fouling spark plugs and fuel mixtures—an essential upgrade for any performance or longevity-focused build.
