Cabin Air Filters — Price Comparison

Cabin Air Filters for 2020 Audi S3

The cabin air filter on a 2020 Audi S3 cleans everything that comes through the HVAC system, and most owners replace it far less often than the 12-month interval filter makers recommend. An aging filter cuts airflow, makes the A/C work harder, and lets pollen and exhaust particulates into the cabin.

We compared 3 offers across major retailers for the 8V platform (2015–2020 8V). Prices range from $9.99 to $18.99 as of the last update.

Best picks

• Best overall: An activated-carbon or HEPA-grade filter — carbon layers absorb exhaust odors in traffic, and finer media catches smoke and smog particles.
• Best budget: A standard particulate filter. It handles dust and pollen fine; you mostly give up odor absorption.

What to look for

• Airflow direction arrows must point the right way on installation — backwards filters degrade quickly.
• If you park under trees or drive dirt roads, halve the replacement interval.
• Carbon filters are worth the upcharge for city commuting; less so in rural areas.

Enthusiast platform note: this chassis has a deep aftermarket, so OEM-replacement parts listed here sit alongside dedicated performance lines. If you're modifying rather than maintaining, check the brand's motorsport catalog for upgraded versions of the same part.
