for active crankcase ventilation

Replace your crankcase breather with the original

The Alfdex oil mist separator is a unique product that uses the centrifugal separation technique to prevent unclean ventilated crankcase gases returning to the inlet of diesel engines or being emitted to the environment. It’s designed to last the life-time of the engine however, certain conditions may cause it to wear more than expected or the engine has reached its lifetime.

By only replacing the upper plastic part of the separator you will have a fully functioning Alfdex oil mist separator again. See the instruction video below.
