Description
Fleetguard CV50626 is the OE-spec crankcase ventilation cartridge for Cummins ISX11.9, ISX12, ISX12N, and X12 engines (2010+ EPA-emissions), replacing Cummins 2869874 and 2895324. The polypropylene coalescer element with centrifugal flow guides captures 98%+ of oil-mist particles 5 µm and larger before blow-by gases re-enter the intake, protecting the turbocharger, charge-air cooler, and EGR/aftertreatment hardware while reducing oil consumption.
Signs You Need a New Crankcase Ventilation Filter
- Increased oil consumption requiring more frequent top-offs
- Oil film or residue inside the turbo inlet pipe or charge-air cooler
- Oil leaks at valve cover gaskets or rear main due to elevated crankcase pressure
- Rough idle, decreased fuel economy, or reduced engine performance
- Blue or white smoke on cold start indicating oil entering the intake
- Service interval reached (1,000 hours)
