Crankcase Ventilation Filter Separator & Gasket for Volvo

This crankcase ventilation filter separator and gasket replaces OEM part numbers 21373547 and 20532891, maintaining proper crankcase pressure and efficient oil separation for Volvo D13 engines.

Overview

The crankcase ventilation filter separator is essential for removing oil mist from blow-by gases before they re-enter the intake, protecting the turbo and aftercooler on your Volvo D13. Designed as a direct replacement for the factory separator and gasket, it restores the closed ventilation system’s efficiency. Fleet operators and owner-operators rely on this part to sustain emissions compliance and extend engine life in demanding on-highway and vocational applications.
