Radium Dual Fluid Lock Catch Can Kit - Subaru BRZ/Toyota 86

Radium Dual Fluid Lock Catch Can Kit — Subaru BRZ / Toyota 86 / Scion FR-S

An oil catch can is essential to protect the engine from elevated levels of crankcase blow-by accumulated during aggressive driving. Excess oil-saturated air circulating back into the intake stream degrades performance, promotes sludge buildup, and in turbocharged applications, reduces intercooler thermal efficiency. The Radium Dual Fluid Lock Catch Can Kit provides a complete closed-loop solution for the Subaru BRZ, Toyota 86, and Scion FR-S — covering both the PCV and CCV circuits for maximum engine protection.

Each catch can features large 10AN ORB ports, a 4AN ORB drain port, 2-step oil separation baffling, and an O-ring sealed dipstick. The kits do not vent to atmosphere (VTA) — making them emissions compliant and track legal. Closed-loop systems route clean filtered air back through the engine to promote negative crankcase pressure for optimal performance and prevent oil vapours entering the cabin.

Suits:

• Subaru BRZ (all years)
• Toyota 86 (all years)
• Scion FR-S (all years)

Platform Notes:

• Compatible with both Right Hand Drive (RHD) and Left Hand Drive (LHD) vehicles.
• Some brake line clearancing may be necessary on RHD installations.
• Compatible with all current aftermarket forced induction kits.
• Uses factory bosses and holes for mounting — no cutting, drilling, or permanent modification required.
• The two catch can kits are completely independent and can be purchased individually or together.

Kit Contents — What’s Included:

• 20-0901 PCV Kit — Mounts on the RH side of the engine bay. Runs inline with the 3/8" PCV (positive crankcase ventilation) valve. Captures crankcase vapour, unspent fuel, and oil sludge that would otherwise be drawn into the intake manifold during idle, cruise, and deceleration. Pressure-sealed design also suits boosted applications.
• 20-0902 CCV Kit — Mounts on the LH side of the engine bay. Runs inline with the 1/2" breather port. Captures crankcase vapours drawn into the intake pipe under high load (WOT). Essential for turbocharged/supercharged applications to prevent oil accumulation in the intercooler.

Catch Can Specifications:

• Ports: 10AN ORB (inlet/outlet), 4AN ORB (drain)
• Baffling: 2-step oil separation
• Dipstick: O-ring sealed
• Capacity: 6 fl oz
• Height (without fittings): 5"
• Outside diameter: 2.45"
• VTA: No — closed-loop, emissions and track legal

Performance Benefits:

• Reduces oil consumption — effectively raises octane
• Cleaner intake air increases engine performance
• Prevents sludge buildup in the intake manifold
• Lowers hydrocarbon emissions
• Protects intercooler thermal efficiency in forced induction applications
