Radium Engineering 08-14 Subaru WRX STI Dual Catch Can Kit

An oil catch can is essential on a performance vehicle to protect the engine from elevated levels of crankcase blow-by oil that accumulate from aggressive driving. Excess oil saturated air circulating back into the air intake stream can lead to degraded performance by depositing oil on the inside of the induction system, intercooler, intake manifold, etc. Radium Engineering catch cans feature large 10AN ORB ports, a 4AN ORB drain port, 2-step oil separation baffling, and an O-ring sealed dipstick.

These kits do NOT vent to atmosphere (VTA), and instead maintain the factory plumbing strategy. 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 from being deteced in 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.
