Performance Engine Air Filter

The APR RF100022 is a performance engine air filter designed as a direct replacement upgrade for the factory intake system. This filter has been optimized on the flow bench to maximize airflow, resulting in up to a 12% increase in CFM over stock and a lower pressure drop. It utilizes a washable and reusable cotton gauze filter media, ensuring adequate filtration and extended service life. Internally, the filter features several enhancements beyond just the media to boost airflow. This design not only helps the engine breathe more freely for increased performance but also sharpens throttle response and turbocharger reaction. It is compatible with any stage of performance modifications and is emissions friendly. The enhanced design also contributes to a subtle but noticeable improvement in engine and turbocharger sounds. This APR air filter is a direct fit for the Porsche Cayenne models from 2019-2021, including various trims such as the base, E-Hybrid, S, Turbo, GTS, and Turbo S E-Hybrid, across different engine displacements (3.0L V6, 2.9L V6, and 4.0L V8).
