Moroso 08-14 Subaru STi (w/Front Mount Intercooler) Air/Oil Separator Catch Can - Billet Alum -Black

If you're looking to keep your 2008-2014 Subaru STi's engine running cleaner, especially with a front-mount intercooler setup, an air/oil separator catch can is a smart addition. Over time, your engine's crankcase ventilation system can push oil vapor into the intake tract. This can lead to carbon buildup on valves and reduced engine performance. This Moroso catch can is designed to trap that oil vapor before it reaches your intercooler and intake manifold.

This catch can is made from solid billet aluminum, which means it's well-built and can handle the heat and pressure under the hood. It's finished in black for a clean look. The design helps to separate oil from the crankcase gasses, collecting it in the can for easy draining. Because it's designed specifically for the STi with a front-mount intercooler, it should fit right into your existing setup.

Keeping your intake system free of oil can help maintain engine power and reduce the need for more involved cleaning down the road. Make sure to check the manufacturer's instructions for proper installation and periodic draining of the collected oil.
