Radium [FR-S/BRZ/86] PCV Side Catch Can Kit Fluid Lock

An oil catch can is essential to protect the engine from elevated levels of crankcase blow-by accumulated from aggressive driving. Excess oil-saturated air circulating back into the air intake stream can lead to degraded performance.Radium Engineering catch cans feature large 10AN ORB ports, a 4AN ORB drain port, 2-step oil separation baffling, andan O-ring sealed dipstick.

FEATURES
-Less oil consumption effectively raises octane
-Cleaner air increases engine performance
-Prevents sludge buildup in the intake
-Lowers hydrocarbon emissions
-Capacity: 7 fluid ounces
-Height (without fittings): 5 inches
-Outside Diameter: 2.45 inches

COMPATIBILITY
12-21 Toyota 86
12-20 Subaru BRZ
12-16 Scion FR-S

The two oil catch can kits are completely independent of each other and are sold individually or together. They do NOT vent to atmosphere (VTA), thus are emissions and track legal. Closed loop systems route clean filtered air back in through the engine to be burned and to promote negative crankcase pressure for optimal performance. Furthermore, closed systems prevent unwanted oil vapors into the cabin.

This catch can runs inline with the 3/8″ PCV (positive crankcase ventilation) valve. When the intake manifold pressure is close to or greater than atmospheric pressure, the PCV “check” valve closes and, thus, this hose experiences no flow. Conversely, the PCV hose will experience “metered” vacuum when the engine is idling, steady state cruising, and decelerating. This would normally draw unwanted crankcase vapor, unspent fuel, and oil sludge into the intake manifold immediately after a high load run.

Note: Because the Radium catch cans are pressure sealed, they are great for boosted applications as well so connecting to the intake manifold is permitted.
