*For RHD vehicles, our Universal Dual Catch Cans must be used for custom mounting and plumbing. *For 02-05 Subarus with a cable-actuated throttle body, our Cruise Control Relocation Bracket must be used. For a maintenance-free solution, consider the Radium AOS-R. The frequency will depend on how much sludge is collected which varies from vehicle to vehicle.

Shown in green, the 20-0608 kit has machining provisions for 02-21 Subaru Impreza/Forester unibody compatibility.Īs shown below, an aluminum heat shield is provided to prevent radiant exhaust temperatures from disturbing the oil condensation process.įurthermore, removing the 4 heat shield bolts makes catch can servicing simple and straight forward.Ĭatch cans must be maintained and emptied on a regular basis. As shown below, the low profile design only extends 4.8" (122mm) off the strut tower. The catch cans are not compatible with RHD vehicles as the kit installs on the RH strut tower. Furthermore, closed loop systems prevent unwanted oil vapors from being detected in the cabin. This closed-loop system routes clean filtered air back in through the engine promoting negative crankcase pressure for optimal performance. 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. 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. An oil catch can is essential for engine protection from elevated levels of crankcase blow-by oil that accumulate during aggressive driving.
