Dual catch can kit for the Nissan 350Z and Infiniti G35.

Both catch cans mount near air filter. Check for clearance before ordering. Not compatible with OEM Nissan air filter box.

The dual catch can consists of a PCV and a CCV catch can. The dual catch can bracket mounts in the front LH portion of the engine bay and is NOT compatible with the factory air box.

The PCV catch can runs inline between the PCV valve and the intake pipe. 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. Note: No inline check valve is required since Radium catch cans are pressure sealed. This means a direct intake manifold connection is permitted.

The CCV catch can runs inline between the crankcase vent (CCV) port and the intake pipe. 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.
