ETS 15+ Subaru WRX Air Filter - DryFlow Filter

This DryFlow replacement fits the ETS 2015–2021 WRX intake, with ETS also listing the SP-3603 fitment for 2022+ WRX. I'd choose the dry-filter option when I want to service the intake without adding filter oil. Use it to replace a damaged or worn filter while retaining the matching ETS inlet geometry. Confirm the part number against the existing intake. ETS lists a restriction on direct shipment of this item to California.
