Fitment Notes

• Application is for Audi vehicles using the specified factory panel-filter airbox.
• A4, A5, allroad, and Q5 fitment varies by engine, market, model generation, and factory airbox configuration.
• Selected diesel applications are market-specific and are not universal across North American vehicles.
• Audi A4 Quattro and A5 Quattro applications use the Quattro AWD drivetrain; drivetrain designation does not change the filter where the same factory airbox is specified.
• Some A4 and A5 applications are specifically identified as 8K/B8 or 8T/8F platforms and/or require the factory panel-filter configuration.
• Verify the exact vehicle's factory airbox and engine application before installation.

Product Description

The AEM 28-20945 DryFlow Panel Air Filter is a washable and reusable replacement engine air filter engineered for specified Audi applications. Its non-woven synthetic media provides a balance of airflow and filtration while capturing up to 99% of harmful contaminants. The oil-free DryFlow design eliminates the need for filter oil during servicing and provides a convenient alternative to conventional disposable filters.

Measuring 12.688 inches long by 5.063 inches wide and 1.5 inches high, the 28-20945 is designed as a direct replacement for the specified factory panel-filter application. It covers selected Audi A3, A4, A5, A4 allroad, allroad, and Q5 vehicles with 1.8L and 2.0L four-cylinder engine configurations, including selected Quattro AWD and market-specific diesel applications.

The reusable DryFlow construction makes this filter suitable for daily street vehicles and performance-oriented applications where long-term serviceability and consistent airflow are desired. Because factory airbox configurations vary by engine, platform, market, and model year, the exact vehicle and factory filter configuration should be confirmed before installation.
