Detailed Description

The ATP Parts OE Replacement line focuses on direct-fit service parts that match the original application. CF-166 is a particulate cabin air filter for BMW HVAC systems, made to filter the air entering the passenger compartment and maintain cleaner interior air quality during everyday driving. It is a practical replacement choice for BMW 528i, 535i, 550i, M5, and related models listed in the fitment data.

Use ATP Parts CF-166 when replacing a clogged or contaminated cabin filter in BMW 525i, 530i, 645Ci, or other supported vehicles from 2004-2010. The filter media’s static charge helps hold fine airborne debris in the filter instead of letting it pass into the cabin.

What It Helps Address

• Reduced cabin air filtration from a dirty or restricted filter
• Pollen entering the passenger compartment
• Dust spores circulating through the HVAC system
• Musty or stale airflow caused by an overdue filter change
• Loss of airflow from a loaded cabin filter

Installation Notes and Tips

Verify the vehicle’s year, model, and HVAC filter application before ordering. Fitment includes BMW models such as 2008-2010 528i, 2009-2010 528i xDrive, 2008-2010 535i, 2010 535i GT, 2006-2010 550i, 2006-2010 M5, and 2004-2005 645Ci. Some applications in the fitment data note particulate cabin air filter service, and 2004-2005 525i and 530i applications note two required per vehicle in the catalog data.
