Detailed Description

The Baldwin PA4370 is a cabin air filter made for HVAC filtration in select Ford Escape, Mazda Tribute, and Mercury Mariner models. Its OE-style sizing and attached gasket support proper fitment in vehicles that use the rectangular cabin filter format, including applications listed with FP49 and FP-49 OE references. This part number, PA4370, is a practical replacement choice when servicing the cabin air filtration system on 2001-2008 Ford Escape, 2001-2006 Mazda Tribute, and 2005-2006 Mercury Mariner models.

This part cross-references Motorcraft FP46 and FP49 for the same application.

What It Helps Address

• Reduced airflow through a dirty or restricted cabin filter
• Dust and debris entering the HVAC intake path
• Musty or stale cabin air caused by a loaded filter
• Loss of HVAC efficiency from filter restriction
• Service replacement for OE-numbered cabin filter applications

Installation Notes and Tips

Verify the vehicle’s OE filter reference and housing style before ordering, since some listed applications are optional and some 2007 Ford Escape listings note a rectangular configuration. Confirm the filter dimensions and gasket style match the existing housing. Replace the cabin air filter during routine HVAC service to maintain consistent airflow.

Quality Assurance

Baldwin manufactures filtration products for automotive service applications, and the PA4370 is built to match the listed OE replacement references and fitment data for the specified Ford, Mazda, and Mercury vehicles.
