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

This Moroso air-oil separator catch can kit includes the small-body billet aluminum catch can, mounting bracket, and necessary hoses and fittings for installation on your 2004-2007 Subaru STI or 2006-2007 WRX. It's designed to capture oil and moisture from the crankcase vapors before they can enter the intake system, helping to keep your engine cleaner and running more efficiently. This is especially important for turbocharged Subarus, where blow-by can be more significant.

The catch can itself is made from strong billet aluminum, which is lightweight and resists corrosion. The small body design is intended to fit in tighter engine bays, and the included mounting bracket ensures a solid installation. By separating oil and moisture from the air, this system helps prevent detonation and keeps your intercooler and intake tract free of oil buildup, which can degrade performance over time. It's a well-built component that addresses a common issue on these performance Subarus.

When installing, pay attention to how the hoses are routed to ensure they don't rub against any moving parts or hot surfaces. This catch can is a popular choice for Subaru owners looking to maintain their engine's health and performance.
