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

Easy to install and had all the parts included. I did have some bad drone from my straight pipe on my Focus ST but with this it cut most of it out! Would recommend to anyone with bad cabin drone. Only thing was I added some Teflon tape on the threads to hold the little bolt in place. Without the tape the bolt kind of feels loose in the housing and I didn’t want to chance it going into the engine.

Day late but hey can't help the amazon team they be late sometimes but hey the item is super solid metal and it bolted right in only downside is I didn't have the right size wrench for the nipple to true turbo so I had to use a paper towel and slightly bigger wrench otherwise I know have true turbo stututut sounds instead of my bov acting like a 90 year trying to blow out there birthday candles every ten seconds lol 😆 2018 focus st
