Moroso 04-07 Subaru STi/06-07 WRX Air/Oil Separator Catch Can - Small Body - Billet Aluminum - Black

If you're pushing your 2004-2007 Subaru STi or 2006-2007 WRX hard, you know that oil blow-by can become a real issue. This Moroso air/oil separator catch can is designed to help keep that oil vapor out of your intake system. By trapping the oil mist before it can get recirculated, it helps maintain cleaner intake components and can prevent detonation issues caused by oil contamination.

This catch can is made from solid billet aluminum, which is a strong and lightweight material. It features a compact design, making it easier to find a spot for it in the engine bay. The black finish gives it a clean look under the hood. Moroso is a well-known name in performance parts, and this catch can is built to handle the demands of a performance Subaru engine.

This kit is designed as a direct fit for the specified Subaru models, meaning it should install without major modifications. Keeping your intake tract clean is key to consistent performance, especially when you're running your car at its limits.
