Crankcase Breather.

Crankcase Breather – Mopar (5093067AA)

The Mopar Crankcase Breather (5093067AA) is a Genuine OEM engine ventilation component engineered to regulate pressure within the crankcase on compatible Chrysler, Dodge, Jeep, and Ram vehicles. The crankcase breather plays a critical role in allowing controlled ventilation of blow-by gases while helping prevent excessive internal pressure buildup. Proper crankcase ventilation supports engine efficiency, seal longevity, and overall emissions system performance. Manufactured to strict Mopar factory specifications, this component ensures precise fitment and dependable operation.

Constructed from high-temperature resistant molded polymer housing with integrated filtration or flow-regulating element (application dependent), the crankcase breather is designed to withstand continuous exposure to oil vapor, heat, and engine vibration. The internal design allows vapors to be routed appropriately while limiting contamination and maintaining balanced airflow within the engine’s ventilation system.

The 5093067AA crankcase breather is developed as a vehicle-specific direct-fit component, matching original mounting configuration, hose connection diameter, and flow characteristics. Maintaining OEM dimensional and functional accuracy is essential to ensure proper crankcase pressure regulation and compatibility with related PCV system components. Aftermarket breathers that deviate from factory specifications may lead to improper ventilation or oil vapor management issues.

For professional technicians, installing a Genuine Mopar crankcase breather ensures compliance with manufacturer engine ventilation and emissions standards during maintenance or repair procedures. For experienced DIY vehicle owners, selecting the OEM breather eliminates compatibility uncertainty and restores factory-engineered ventilation performance without modification.

A properly functioning crankcase breather supports stable internal pressure balance, reduced oil leakage risk, and consistent engine operation. Replacing a clogged or damaged breather promptly helps maintain proper ventilation and long-term engine reliability.

• Genuine Mopar OEM crankcase breather

• High-temperature resistant molded construction

• Integrated ventilation flow regulation

• Designed for crankcase pressure management

• Factory-matched connection and fitment geometry

• Vehicle-specific direct-fit configuration

If you are restoring proper engine ventilation or replacing a compromised breather component, the Mopar Crankcase Breather (5093067AA) delivers factory-accurate fitment, durable construction, and OEM-engineered ventilation reliability for your vehicle.
