2015-2021 Subaru WRX Baffled Oil Catch Can PCV Side

The WRX Catch Can is designed to capture excess oil and contaminants that escape past the piston seals into the crankcase. In Subaru WRX engines, blow-by is common, especially with direct injection systems, leading to carbon buildup on intake valves. By capturing oil vapors before they reach the intake, the WRX Catch Can helps prevent carbon deposits, protecting performance and enhancing engine longevity. Oil vapor escapes during combustion, but the WRX Catch Can intercepts this blow-by, ensuring cleaner airflow and preventing contaminants from re-entering the intake. This leads to improved combustion, better throttle response, and overall engine efficiency.
