Product Details

Bosch Cabin Filter P3951WS is designed for drivers who want a direct-fit particulate filter for the vehicle’s HVAC system. The filter media is built with layered synthetic materials that help trap airborne debris, dust, and other environmental particles before they circulate through the cabin. As a Bosch Cabin Filter, this part focuses on maintaining cleaner airflow for passengers while matching OEM standard replacement expectations.

This part cross-references Ford/Lincoln OE reference DG9Z19N619D for the same application. The P3951WS part number is also useful when searching for a Bosch cabin air filter for Ford Fusion, Lincoln MKZ, or Ford Edge service replacement needs.
