Product Details

The ATP Parts Premium Line focuses on cabin air filtration performance for everyday driving conditions. On vehicles such as the Buick Lucerne, Cadillac DTS, and Pontiac Bonneville, the GA-3 helps maintain cleaner air through the HVAC vents by combining particle capture with activated carbon odor absorption. The result is a practical replacement filter for drivers who want to address dust, pollen, and outside exhaust odors at the source.

Part number GA-3 is listed for multiple GM platforms, including Buick, Cadillac, Oldsmobile, and Pontiac models from 2000-2011. If you are searching for a cabin air filter for a 2006-2011 Cadillac DTS or a 2000-2005 Buick LeSabre, GA-3 is the relevant part number to verify against your vehicle’s HVAC filter location and service requirements.

What It Helps Address

• Dust and airborne debris entering the passenger compartment
• Pollen and other fine particles moving through the HVAC vents
• Diesel exhaust and other outside odors
• Reduced cabin air freshness from a loaded filter
• Restricted airflow caused by a dirty cabin filter

Installation Notes and Tips

Verify the vehicle year, make, and model before ordering, since cabin filter locations and access points vary by application. Replace the filter according to the vehicle service schedule or sooner if airflow drops or odors become noticeable. When servicing the HVAC system on a Buick Lucerne, Cadillac DTS, or similar GM application, inspect the filter housing for debris before installing the new filter.

Quality Assurance

ATP Parts positions this filter in its Premium Line with activated carbon media for odor control and particle capture. The manufacturer describes the filter as a high-protection cabin air filtration solution for select GM vehicles.
