An oil catch can is essential for engine protection from elevated levels of crankcase blow-by oil that accumulate during 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.

This kit contains two independent catch cans, each plumbed into different parts of the PCV system. The cans 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 promoting negative crankcase pressure for optimal performance. Furthermore, closed loop systems prevent unwanted oil vapors from being detected in the cabin. 

The catch cans are not compatible with RHD vehicles as the kit installs on the RH strut tower. As shown below, the low profile design only extends 4.8" (122mm) off the strut tower.
