Moroso Catch Cans Black 2004-2007 STI | Twin Small Body Design | Engine Breather Catch Can
Overview
The Moroso Catch Cans Black for 2004-2007 Subaru WRX STI models are engineered to improve engine longevity and performance by capturing excess crankcase vapors, oil mist, and moisture before they can reenter the intake tract. Designed specifically for the Subaru WRX STI platform, 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 product is ideal for Subaru enthusiasts looking to maintain a cleaner intake system and optimize their engine’s efficiency, especially on turbocharged models equipped with front mount intercoolers.
Moroso’s approach to catch can design focuses on durable construction and effective vapor separation. Featuring billet aluminum bodies with internal baffling and mesh media, these catch cans efficiently trap contaminants while maintaining proper ventilation of the PCV system. The black anodized finish not only provides corrosion resistance but also complements the engine bay aesthetics of the WRX STI. The kit includes heavy-duty brass fittings, fuel/emission/PCV vapor hose, and stainless steel mounting hardware for a secure and professional installation.
By preventing oil and moisture from entering the intake manifold and intercooler, the Moroso Catch Cans help maintain consistent combustion quality and intercooler efficiency. This translates to more reliable power delivery and reduced maintenance concerns for Subaru owners who demand both performance and durability from their vehicles. The twin small body design is tailored to fit the specific crankcase ventilation requirements of the 2004-2007 STI models, ensuring optimal capture and venting of vapors.
