Why Replace Your Cabin Air Filter?

A clogged or worn cabin air filter reduces airflow through your HVAC system, allows contaminants and allergens into your cabin, and can cause unpleasant odors. Most manufacturers recommend replacing the cabin air filter every 15,000–25,000 miles or once a year. Learn more about vehicle maintenance best practices at the EPA's Green Vehicles resource page.

Frequently Asked Questions

Q: Which Audi models is this activated carbon cabin air filter compatible with?

A: This cabin air filter is designed to fit the Audi A3, S3, and TT. It replaces OEM part numbers 1K1819653A and CUK 2939. Always cross-reference the part number with your vehicle's owner manual or parts guide to confirm fitment before installation.

Q: What is the benefit of an activated carbon cabin air filter over a standard filter?

A: Most automotive manufacturers recommend replacing the cabin air filter every 15,000–25,000 miles or approximately once a year, whichever comes first. If you frequently drive in dusty or high-traffic urban environments, you may want to replace it more often. Check your vehicle owner's manual for the manufacturer's specific recommendation.
