aFe Magnum FLOW Pro 5R Performance Air Filter for Select Subaru 2017-2026 (2.0L)

Fits select 2017-2026 Subaru Ascent, Crosstrek, Forester, Impreza, Legacy, Outback, and WRX (2.0L). Replace your restrictive factory paper filter with the aFe POWER Magnum FLOW Pro 5R performance air filter for improved airflow and protection.

The Pro 5R media features five layers of progressively finer, pre-oiled cotton gauze. This design provides up to a 53% increase in airflow over the stock intake while maintaining high filtration efficiency. The rounded, evenly spaced pleats maximize surface area for greater dust-holding capacity, ensuring consistent performance even as the filter accumulates debris. Constructed with a full 360-degree polyurethane frame, this filter maintains its shape under high engine bay temperatures and uses a progressive bump seal to ensure a leak-free fit without the need for gaskets or sealants.
