Radium Engineering Fluid Lock Dual Catch Can Kit Nissan 370Z (Z34)

The Radium Engineering Dual Catch Can Kit for the Nissan 370Z is designed to maintain engine bay symmetry and optimise crankcase ventilation performance on VQ37VHR engines. This closed-loop system installs cleanly using factory mounting points—no cutting, drilling or permanent modifications required.

Each catch can features large 10AN ORB ports, a 4AN ORB drain port, and an internal 2-stage baffling system to efficiently separate oil from crankcase vapours. A sealed dipstick allows for quick and easy fluid level checks.

Mounted to the RH and LH strut towers, the two catch cans run inline with the twin PCV valves on the valve covers, retaining full OEM functionality. When intake manifold pressure is high (boost), the PCV check valves close, isolating the catch cans. During light load or vacuum, the catch cans filter blow-by gases before they enter the intake manifold.

Note: No inline check valve is needed. Radium catch cans are pressure sealed and can be directly plumbed to the intake manifold.
