- 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.
