1、It is a sandwich type adapter that can be installed between the existing solenoid valve and the turbocharger housing, which will prevent the recirculation of hot air and reduce "lag". 2、This atmospheric diverter for OEM valves discharges pressurized air into the atmosphere and produces a "whistling" sound when the throttle is raised. 3、By installing an adapter between the existing solenoid and the turbine housing (this only requires the removal of 2 bolts), the air is redirected to the atmosphere instead of being recirculated, thus improving the overall pleasure of the driver. 4、Allow supercharge to recirculate from the supercharge side back to the intake side around the supercharger. 5、The new high-quality adapter can work well on your car.
