The Radium catch can kit for GM LS-based V8 engine includes everything needed for a complete installation. The catch can is plumbed in-line with the PCV tube and draws out oil and water condensation from the PCV gasses that would otherwise be drawn into the intake manifold. Radium Engineering offers two independent S2000 oil catch can kits that are sold individually or together. They do NOT vent to atmosphere (VTA), thus are emissions and track legal. Closed loop systems route clean filtered air back in through the engine to be burned and to promote negative crankcase pressure for optimal performance.
