Detailed Description

What It Helps Address

• Cracked crankcase breather filter housing
• Clogged crankcase ventilation filter media
• Missing original crankcase breather element
• Restricted crankcase ventilation airflow
• Oil and heat-related filter deterioration

Installation Notes and Tips

Verify the housing shape, stem outside diameter, and overall dimensions before ordering. This part uses a cartridge mounting type and is not reusable, so replacement service should follow the vehicle’s existing crankcase ventilation filter configuration. Confirm the application against the original part number 904-7902 and the vehicle’s OE layout before installation. For fitment-based searches, use the exact vehicle configuration rather than a universal filter listing.

Quality Assurance

Dorman manufactures this replacement crankcase ventilation filter to match original fit and function, using materials selected for exposure to engine oil and heat. Part number 904-7902 is built as a direct replacement service part for specific applications.
