ACDelco Cabin Air Filter CF197 (GM 13503677) OE Replacement — Multi-layer Particle Capture

ACDelco CF197 (GM 13503677) is an OE cabin air filter engineered to trap particulates and help keep vehicle HVAC systems cleaner in compatible GM models.

Designed, validated, and backed by General Motors, the ACDelco GM Original Equipment cabin air filter CF197 matches the specifications used in production for select Cadillac, Chevrolet, Buick, GMC and other GM-brand vehicles. Its multi-layered, non-woven media is built to capture airborne particles before they reach the ventilation system while maintaining airflow for the HVAC unit. This replacement part corresponds to GM part number 13503677 and is intended as a direct-fit option for vehicles that list CF197 or that GM number in their parts catalog.

How does this cabin air filter fit my GM vehicle?

The CF197 is manufactured to GM’s OE fit and installation tolerances, so it installs the same way as the original filter it replaces. Match the GM part number (13503677) or the vehicle-specific parts list to confirm compatibility before purchase. If your vehicle’s parts catalog or owner’s manual lists CF197 or GM 13503677, this is the correct replacement.

• Direct-replacement design for select GM model cabins
• Compatible where OEM lists CF197 or GM 13503677
• Same size and mounting features as factory-installed filters
• Easy swap during routine HVAC maintenance

What materials and construction does the filter use?

ACDelco’s CF197 uses long non-woven media with a multi-layered construction that creates separated filtration layers. This arrangement helps trap particles while preserving airflow, supporting the HVAC system’s performance. The media and assembly are chosen to meet GM’s engineering and validation requirements for service parts.

• Non-woven, long-fiber media for particle capture
• Multi-layer construction to contain different particle sizes
• Manufactured and validated against GM design standards
• Designed to balance filtration efficiency with airflow

What maintenance benefits can I expect from replacing the cabin filter?

Changing the cabin air filter regularly helps reduce the accumulation of dust and debris in the HVAC intake and ducting, which can improve cabin air quality and maintain system efficiency. A fresh OE-spec filter also helps ensure the blower motor and evaporator are less exposed to particulate buildup. Follow vehicle manufacturer service intervals or inspect the filter periodically for heavy contamination.

• Reduces dust and airborne particulate entering the cabin
• Helps maintain HVAC airflow and system efficiency
• Minimizes particulate buildup on blower and evaporator components
• Simple, low-cost preventive maintenance step

Is this the same filter GM uses in production?

ACDelco GM Original Equipment parts are engineered and tested to the same standards used by GM, and many service parts are validated by GM engineers. Some items previously labeled as GM Genuine Parts or ACDelco Professional may now appear under the ACDelco GM Original Equipment designation. CF197 is produced to meet those OE requirements for the specified vehicle list.

• Engineered to GM specifications and validation processes
• Serves as the OE-style service replacement for compatible models
• May have previously been offered under GM Genuine Parts or ACDelco Professional
• Backed by General Motors engineering and quality practices

Who is this for: The ACDelco CF197 (GM 13503677) cabin air filter is aimed at owners and technicians of compatible GM vehicles who prefer OE-validated replacement parts. It suits drivers who want a direct-fit service filter that meets GM’s engineering standards and helps protect the HVAC system from dust and debris. Ideal for routine maintenance intervals, DIY filter changes, and professional service shops that specify OE-quality components for Chevrolet, Buick, GMC, Cadillac and other supported models.
