This is the Radium Engineering Dual Fluid Lock Catch Can Kit. Catch can kits are essential to Subaru platforms to protect the engine from elevated levels of crankcase blow-by accumulated from aggressive driving. Excessive oil-saturated air circulating back into the air intake stream can lead to degraded performance. The Radium Engineering catch can kit features large 10AN ORB ports, a 4AN ORB drain port, a 2-step oil separation baffling, and an O-ring sealed dipstick.

 Radium Engineering Dual Fluid Lock Catch Can Kit


  • Includes (2) independent catch cans that are plumbed into different parts of the PCV system
  • The cans do NOT vet to the atmosphere and instead maintain the factory plumbing strategy
  • This is a closed-loop system that routes clean filtered air back in through the engine promoting negative crankcase pressure for optimal performance
  • Closed-loop systems also prevent unwanted oil vapors from being directed into the cabin
  • An aluminum heat shield is provided to prevent radiant exhaust temperatures from disturbing the oil condensation process
  • Effectively raises the octane
  • Cleaner air increases engine performance
  • Prevents oil sludge in the intake system
  • Bolt-in installation
  • Easy servicing with dipsticks
  • 8-ounce fluid capacity per can



  • During closed or light throttle, the PCV valve is open allowing fresh air to be pulled into and through the crankcase and into the intake manifold
  • The PCV line catch can will receive the most oil collection under this condition
  • The crankcase catch can will not see any oil collection in this circumstance
  • Under full throttle conditions, the PCV valve is closed (you do not want turbo boost entering the crankcase), and crankcase gasses are pushed out of the engine and into the turbo air inlet pipe



  • These catch cans are not compatible with RHD vehicles as the kit installs on the RH strut tower
  • The low-profile design only extends 4.8" off the strut tower
  • 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
