Radium Engineering BMW 135I/335I/535I N54 Catch Can Kit Fluid Lock

The Radium Engineering BMW 135I/335I/535I N54 Catch Can Kit Fluid Lock captures oil mist and other crankcase contaminants before they can circulate back through the intake tract. Radiums application-specific catch-can systems pair internal separation media with purpose-built mounting and plumbing for a cleaner crankcase-ventilation installation.

Fitment is specific to BMW 135I/335I/535I N54; confirm the vehicle and surrounding hardware before ordering. Confirm whether the selected configuration is PCV, crankcase, dual-can, VTE, or VTA and verify compatibility with other intake/PCV modifications.
