Features

For the ultimate in engine protection, Radium Engineering recommends this Dual Catch Can Kit, which utilizes both the “PCV” and “CCV” catch can kits.

The PCV catch can kit runs inline between the PCV valve and the intake manifold and promotes clean filtered air back into the engine. When the intake manifold pressure is close to or greater than atmospheric pressure, the PCV “check” valves close and, thus, this hoses experience no flow. Conversely, the PCV hoses 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.

The CCV catch can runs inline between the crankcase vent (CCV) port and the turbo inlet pipe, allowing it to retain factory functionality. At low loads, it experiences atmospheric pressure. However, when the engine is at high load (WOT), the line will experience high flow from the crankcase into the intake system. This would normally lead to oil and sludge accumulation in the air filter intake pipe. The CCV catch can captures this and promotes clean filtered air back into the intake.

Radium Engineering catch cans feature:

• Large 10AN ORB ports
• 4AN ORB drain port
• 2-step oil separation baffling
• O-ring sealed dipstick

These kits mount using factory holes and integrate perfectly with the surrounding components. They do NOT vent to atmosphere (VTA), thus are emissions and track legal. Closed loop systems remove the oil and sludge from the PCV gasses before it is routed to the engine to be burned. A closed loop system also promotes negative crankcase pressure for optimal performance. Furthermore, closed systems prevent unwanted oil vapors from entering the cabin. The dipsticks built into the catch cans allow easy inspection of accumulated fluid. No cutting, drilling or permanent modifications are required.

What is included?

• Two Baffled oil catch cans
• WRX VB specific mounting brackets
• 12AN adapter fittings and hose ends
• 10AN adapter fittings and hose ends
• Stainless steel hardware
• 3/4″ PCV hose
• 5/8″ PCV hose

Notes

1. The PCV catch can kit does not require an extra inline check valve since Radium catch cans are pressure sealed.

2. The CCV catch can kit does NOT address blow-by from the PCV side of the crankcase.

Install Note

The CCV kit is compatible with the OEM air duct. The PCV catch can mounts to threaded bosses on the ABS unit. Permanent modifications are not required.
