Wix WA11221 Engine Crankcase Breather Element

Wix WA11221 Crankcase Breather Element

The Wix WA11221 is an engine crankcase breather element for crankcase ventilation systems that manage blow-by gases. It filters oil residue and other contaminants before the gases are recirculated or vented, helping maintain cleaner crankcase ventilation on heavy-duty diesel applications.

• Synthetic media material for crankcase ventilation filtration
• Engine crankcase breather element for heavy-duty service
• Designed for crankcase ventilation filter applications
• Dimensions: 16.45 in. length, 6.93 in. width, 2.87 in. height
• Cross-reference: Baldwin CV15010

How It Works

During combustion, pressure can force gases past the piston rings and into the crankcase. The Wix WA11221 helps the CCV system separate oil residue and other contaminants from those gases before they are routed back into the combustion process or released. This makes it a direct-service part for Ram 2500 and Ram 3500 diesel crankcase ventilation maintenance, including 2020-2024 Ram 2500, 2014-2018 Ram 2500, 2020-2024 Ram 3500, 2017-2018 Ram 3500, and 2014-2015 Ram 3500 applications.

Common Issues Addressed

• Oil residue buildup in the crankcase ventilation path
• Contamination in blow-by gas routing
• Restricted crankcase ventilation filter performance
• Maintenance needs on Ram 2500 and Ram 3500 CCV systems

Installation Notes

Verify the vehicle year, engine configuration, and existing crankcase ventilation filter style before ordering. Confirm the part number WA11221 against the original filter and inspect the housing and sealing surfaces during service. This part also cross-references Mopar 68002433AC for the same application.

Quality Assurance

Wix manufactures this crankcase ventilation filter with synthetic media and heavy-duty construction for emission control service. The WA11221 is built for the listed Ram 2500 and Ram 3500 fitments and follows the application requirements shown in the catalog data.
