Moroso Catch Cans Black 2008-2014 STI | Twin Small Body Design | Engine Breather Catch Can
Overview
The Moroso Catch Cans for the 2008-2014 Subaru WRX STI are engineered to improve engine performance and longevity by capturing excess crankcase vapors, oil mist, and moisture before they can re-enter the intake tract. Designed specifically for Subaru STI models equipped with a front mount intercooler, these catch cans help prevent the buildup of oil deposits on intake valves and reduce the risk of detonation caused by contaminated intake air. This system is ideal for enthusiasts looking to maintain a cleaner intake environment and optimize their engine’s efficiency.
Moroso’s approach centers on precision engineering with billet aluminum bodies featuring internal baffling and mesh media to effectively separate oil and vapor from the PCV system. The twin small body design is compact enough to fit in tight engine bays while providing sufficient capacity for proper ventilation. The black anodized finish not only offers corrosion resistance but also complements the engine bay aesthetics of the Subaru STI.
By installing Moroso catch cans, Subaru owners benefit from cleaner intake air, which can translate to more consistent combustion and improved intercooler efficiency. This is particularly important for turbocharged STI engines where maintaining optimal air quality directly impacts power delivery and reliability. The included hardware and mounting components ensure a secure and professional installation tailored to the STI’s factory PCV system.
