Choosing a catch can or air-oil separator

A catch can collects oil mist and condensation from crankcase vapour and needs periodic draining. Radium AOS-R systems return separated oil to the engine and require suitable return plumbing and coolant connections. Choose the system around your engine ventilation layout, mounting space and maintenance needs.

Check whether you need a PCV, crankcase or dual-can setup, and confirm the included brackets, hoses and fittings. Read our Radium catch can buying guide before comparing the products below, or ask us about fitment.
