Moroso Catch Cans Silver 2008-2014 STI | Small Body Design | Engine Crankcase Vapor Separator
Overview
The Moroso Catch Cans Silver for the 2008-2014 Subaru WRX STI are precision-engineered components designed to improve engine performance and longevity by capturing excess crankcase vapors, oil mist, and moisture before they can reenter the intake tract. These catch cans are specifically developed for Subaru STI models equipped with front mount intercoolers, 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.
Moroso’s approach combines durable billet aluminum construction with internal baffling and mesh media to effectively separate oil and moisture from the crankcase vapors. The small body design offers a compact solution that fits a wide range of engine bays without sacrificing capacity or performance. Heavy-duty brass fittings, stainless steel mounting hardware, and a billet aluminum clamp ensure a secure and reliable installation tailored to the Subaru STI platform.
For Subaru enthusiasts, maintaining clean intake air is critical to preserving engine health and optimizing power delivery. By preventing oil deposits and moisture buildup, these catch cans help sustain consistent combustion quality and intercooler performance, especially under boost conditions. The Moroso catch cans provide a practical upgrade that supports both daily driving reliability and spirited driving demands.
