4-0300 Symposer Delete with Pressure Port Compatible with Ford Focus ST250 | Compatible with Ford Focus ST/ST250 2013-2018, Choose 1/8" NPT plug or 3/16" Hose Barb fitting, Include Plastic block off cap

I was hesitant to buy this because I thought a name brand would be better. I was wrong. Great quality. Perfect fit. Easy install. Great way to save money for the same quality.

Perfect for Focus ST, super duper easy install and cleans up the engine bay a lot. No problem with packaging or anything!

Save your money and buy this over the name brand options, they do the exact same thing. Easy installation and fit perfectly.

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

The product works as intended and for a reasonable price (compared to the others charging way more for the same thing). I will give you this tip, though: if you plan on running any kind of aftermarket BOV, then ditch the provided fitting and replace it with one that has a 5/16" barbed hose end; the one provided is woefully inadequate for anything more than just a boost gauge. The new fitting I chose is the 45-degree style that helps routing the hose to the BOV easier.

It works great and you can run a line from it to your bov for a true vacuum source. But the main issues is that they charge 30 bucks for it!! It is a piece of aluminum with a small O ring on it. Its just hard to justify the purchase just for a little bit less cabin noise.

Simple and easy to install!

Purchased this piece to do the sound symposer delete on my 2018 focus ST. Everything necessary for install came included in the package. Install itself was pretty easy too. Trickiest part was getting off the 8mm bolts connecting to exhaust manifold. Otherwise, very straightforward install. No check engine light either, and I can now hear my Ford performance exhaust more clearly without the sound symposer pumping in the fake engine sound. Good mod for $20.

easiest way to grab a boost line!
