Moroso Breather Tank/Catch Can -12An Male Fitting - Billet Mounting Bracket - Aluminum

This Moroso breather tank and catch can kit comes with the aluminum tank itself, a -12AN male fitting, and a billet aluminum mounting bracket. It’s designed to help keep your engine’s oil system cleaner by capturing blow-by gasses and oil vapors before they can recirculate back into the intake system.

Catch cans like this one are a smart addition for many performance builds or even daily drivers looking to improve engine longevity. By trapping oil mist and unburned fuel that gets pushed past the piston rings, you prevent that gunk from contaminating your fresh oil and potentially reducing its lubricating properties. The aluminum construction is well-built for durability, and the included billet bracket makes for a solid mounting solution. The -12AN fitting offers a common and secure connection point for your plumbing.

When installing, you'll typically route a hose from your valve covers or crankcase ventilation system to the inlet of the catch can, and then route the outlet back to your intake or vent it to atmosphere, depending on your setup and local regulations. It’s a good idea to check the can periodically and drain any collected fluid.
