Moroso 04-07 Subaru STi (w/Front Mount Intercooler) Air/Oil Separator Catch Can - Billet Alum -Black

If you're looking to keep your 2004-2007 Subaru STi's engine running cleaner, especially with a front-mount intercooler setup, an air/oil separator catch can is a smart addition. This Moroso unit helps capture oil vapor and blow-by gasses that can otherwise recirculate back into your intake system, potentially reducing performance and increasing carbon buildup on your valves.

This catch can is constructed from durable billet aluminum with a black finish, giving it a solid feel and a clean look under the hood. It's designed to be a direct fit for your STi, making installation straightforward. By trapping oil mist before it enters the intake, it helps maintain a cleaner engine environment, which can lead to more consistent performance and potentially extend the life of your engine components. The included hardware ensures you have what you need to get it installed properly.
