Oil separator/PCV, breather hose and heating element, sold as a complete assembly
The heating element on this component, is a small but, critical component, as it is important to not have the crankcase vapors freeze. (water vapor is present) Oil and water emulsification forms when vapors come in contact with cooler temperatures, freeze and ice crystals can then easily erode the turbocharger intake blades. Strange but, true.
