Moroso Catch Cans Silver 06-07 WRX / 04-07 STI | Small Body Design | PCV System Oil Separator
Overview
The Moroso Catch Cans Silver Small Body is a precision-engineered oil separator designed specifically for Subaru WRX (2006-2007) and WRX STI (2004-2007) models equipped with top mount intercoolers. This catch can system is plumbed into the vehicle’s PCV (Positive Crankcase Ventilation) system to capture excess crankcase vapors, oil mist, and moisture before they can re-enter the intake tract. By preventing these contaminants from circulating back into the intake manifold, the catch can helps reduce detonation risk, limits carbon buildup on intake valves, and maintains intercooler efficiency.
Moroso’s design philosophy centers on durable, high-quality materials and effective internal baffling to maximize vapor separation. The billet aluminum body features internal mesh media and baffling to trap oil and moisture efficiently, while heavy-duty brass fittings and stainless steel mounting hardware ensure a secure, leak-free installation. The Small Body version offers a compact footprint, making it ideal for tight engine bays without sacrificing capacity or performance.
For Subaru enthusiasts, maintaining clean intake air is critical to sustaining engine performance and longevity, especially on turbocharged WRX and STI models prone to oil vapor contamination. The Moroso catch can’s ability to reduce oil deposits and moisture in the intake system translates to more consistent combustion, improved throttle response, and better intercooler operation. This catch can is a practical upgrade for anyone looking to protect their Subaru’s engine while supporting reliable power delivery.
