Moroso Catch Cans Black 06-07 WRX / 04-07 STI | Twin Small Body | PCV Catch Can System
Overview
The Moroso Catch Cans Black for 2006-2007 Subaru WRX and 2004-2007 Subaru WRX STI are designed to improve engine reliability and performance by capturing excess crankcase vapors, oil mist, and moisture before they can re-enter the intake tract. These catch cans are specifically engineered for Subaru’s top mount intercooler models, addressing a common issue where factory PCV systems vent contaminants back into the intake manifold. This can lead to detonation, carbon buildup on intake valves, and reduced intercooler efficiency. The Moroso catch cans provide a practical solution for Subaru enthusiasts looking to maintain cleaner intake air and protect their engines.
Moroso’s design philosophy focuses on durability and effective vapor separation. Featuring billet aluminum bodies with internal baffling and mesh media, these catch cans efficiently trap oil and moisture while maintaining proper ventilation. The black anodized finish offers a sleek, OEM+ appearance that complements the engine bay without compromising quality. Heavy-duty brass fittings and stainless steel mounting hardware ensure a secure and long-lasting installation tailored to Subaru’s unique PCV system requirements.
For Subaru owners, especially those running modified or high-mileage engines, the Moroso catch cans help reduce intake contamination and improve combustion consistency. Cleaner intake air translates to more stable performance and potentially longer intercooler and engine life. The twin small body setup is ideal for the 2006-2007 WRX and 2004-2007 STI, where dual catch cans are necessary to properly ventilate the crankcase system. This setup is a smart upgrade for anyone serious about maintaining engine health and maximizing the potential of their Subaru’s turbocharged powertrain.
