21373547 Crankcase Ventilation Oil Separator Fit D13 MP8 Engine 2014-Up Heavy Duty Truck Construction Machinery Aftermarket Replacement Part

OE number 21373547 Crankcase Ventilation Oil Separator is engineered to fit D13 and MP8 engines for heavy-duty trucks and construction machinery manufactured from 2014 onwards. This unit is not compatible with earlier engine generations.

Manufactured to match OEM dimensional and performance standards, the internal multi-stage filter structure efficiently separates oil mist from crankcase blow-by gas, reducing oil consumption, preventing turbo contamination and extending engine service life. All inlet and outlet ports, mounting brackets and sealing surfaces replicate factory specs for direct bolt-on installation without modification.

Constructed with high-temperature resistant housing and durable coalescing filter media, it withstands harsh working environments of long-haul trucks and construction equipment. Ideal replacement for clogged or leaking original separators during routine engine maintenance. Confirm your engine model and production year with sales before ordering.
