Turbocharger diverter valves are an essential replacement item for proper operation of the vehicle's turbocharger system. Dorman's turbocharger diverter valve is designed to the match the originals fit, form, and function, dispersing excess pressure built by the turbocharger during shifting or when removing your foot from the accelerator pedal. Additionally, this part prevents the excess boost from reaching the throttle body, ultimately preventing premature failure of the throttle body assembly. Replacement of a faulty turbocharger diverter valve will prevent acceleration issues and help to restore proper drivability of the vehicle.
