TurboXS dry element drop-in air filter is a direct-fit replacement for 2008-2021 Subaru WRX and STI models, using OEM part numbers 16546AA090 and 16546AA10A. The EPDM rubber base withstands a wide temperature range while coated steel mesh and deep pleats increase filtration surface area without restricting flow. The dry element provides improved flow characteristics and longer service intervals compared to stock while fitting like the OEM filter.
