The Radium Engineering universal air/oil separator vents crankcase vapors back into the engine induction system for a closed-loop setup. Built as a universal kit, it prevents oil buildup in the intake, helps keep inlet air cleaner and lowers hydrocarbon emissions compared with open venting. The AOS is intended to be plumbed back into the induction path to control oil and vapor buildup.
