RICHWEI CP966 is an activated-carbon replacement cabin air filter engineered to fit many Chevy, GMC, Buick and Cadillac models from mid-2010s to early-2020s, helping trap dust, pollen and common vehicle air contaminants.

If your vehicle’s interior air feels dusty, has lingering odors, or the HVAC airflow seems reduced, the cabin air filter is a quick, inexpensive service item to inspect and replace. The CP966 (also referenced by many OEM and aftermarket part numbers) is sized and constructed to match factory housings for a wide range of models including Silverado, Sierra, Equinox, Terrain, Acadia, Enclave, Escalade, and more. This listing supplies one replacement cabin filter with activated carbon layers to address odors in addition to particulates.

Which vehicles does the CP966 cabin air filter fit?

The CP966 is compatible with numerous Chevrolet, GMC, Buick and Cadillac vehicles across several model years. Before ordering, verify your vehicle’s model year and original filter part number to ensure fitment.

How does activated carbon help the cabin environment?

The CP966 includes an activated-carbon layer that adsorbs odors and some gaseous compounds, reducing stale or traffic-related smells inside the cabin. It complements the particle-filtering layers that capture pollen, dust and road debris. While not a replacement for specialized gas-phase filters, activated carbon improves perceived air freshness for everyday driving.

• Adsorbs common odors from road traffic and interior sources.
• Works together with pleated media to trap particulate matter.
• Helps extend the time between odor complaints and cabin refreshes.

How do I replace this cabin air filter and what should I expect?

Most vehicles that use this size filter have an easily accessible cabin filter door behind the glovebox or under a cowl panel. Replacement typically requires only a few minutes and basic tools; consult your vehicle’s owner manual for exact instructions. Expect restored airflow, fewer visible dust particles on vents, and reduced interior odors after installation.

• Locate filter housing (glovebox or cowl area) and remove the old filter.
• Install CP966 in the correct flow direction; reseal the access panel.
• Routine check: replace every 12,000–18,000 miles or sooner in dusty conditions.

Which part numbers and equivalents does this filter replace?

RICHWEI CP966 is offered as a direct-fit aftermarket alternative to many factory and aftermarket references. It cross-references a long list of OEM and third-party numbers, so it’s useful when the original part number is not readily available. Always compare dimensions and the original part code for absolute certainty before purchasing.

• Cross-references include common aftermarket and OEM codes such as CF1196, CAF1904, 13356914 and many others.
• Check your vehicle’s existing filter label for the matching part code.
• One filter per package; verify fitment with your year/make/model before ordering.

It’s a practical choice for fleet maintenance, routine vehicle servicing, or anyone seeking a straightforward OEM-style filter swap.
