Radium Engineering Dual Catch Can Kit - 2008+ Subaru STI | 2008-2014 WRX
An oil catch can is essential on a performance vehicle to protect the engine from elevated levels of crankcase blow-by that accumulate from aggressive driving. Excess oil saturated air circulating back into the air intake stream can lead to degraded performance. These kits do NOT vent to atmosphere (VTA), thus are emissions and track legal. This closed loop system routes clean filtered air back in through the engine and promotes negative crankcase pressure for optimal performance. Furthermore, closed loop systems prevent unwanted oil vapors into the cabin.
This kit contains two independent catch cans, each plumbed into different parts of the PCV system. It is designed for users wanting to keep the function of the the closed loop PCV valve which flows fresh air through the engine block to pull out blow-by gasses.
