If you are looking for this, you should already know what this is and does for your Focus ST. 2014 FoST here and I came here to get this to tame down my Turbosmart 50/50 BOV while it was connected to the solenoid. I used this kit to route a high temp hose to run a true vacuum to the BOV. Now the BOV is no longer going off every time I get off the gas. It now goes off on a decent load. The kit was complete but I would recommend your own zip tie, this one is tiny. Also I used a 90 degree pressure port and teflon taped it as well. All works perfectly! The look of plate is nice and solid with a good o-ring and looks durable
