Radium Engineering Dual catch can kit for the Subaru vehicles 2002 to 2021 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.
Shown in green, the 20-0608-FL kit has machining provisions for 02-21 Subaru Impreza/Forester unibody compatibility. As shown below, an aluminum heat shield is provided to prevent radiant exhaust temperatures from disturbing the oil condensation process.
Furthermore, removing the 4 heat shield bolts makes catch can servicing simple and straight forward.
Catch cans must be maintained and emptied on a regular basis. The frequency will depend on how much sludge is collected which varies from vehicle to vehicle. For a maintenance-free solution, consider the Radium AOS-R.
