3 Port electric boost solenoid. Comes with the Billet bracket, hadware, and vacuum nipples needed. You will need some kind of controller for this, will not work directly with the stock ecu. Will work with most aftermarket ecus, including Haltech, Holley, Aem, Megasquirt, Motec, Link, or any Electric AEM boost gauges. Good for 100% increase over your current wastegate pressure.
