This Turbo XS blow-off valve to intercooler gasket is a rubber-coated metal gasket made for 2015–2021 Subaru WRX STI applications to seal the connection between the blow-off valve and intercooler. Supplied as a direct-fit, vehicle-specific gasket, it is intended to maintain a reliable seal at that junction during turbocharged operation without modifying factory components.
