      Enables Greater Boost. The stock blow-off valve (BOV) is adequate for the every day commuter car. But if you are planning on increasing the boost and power of your EcoBoost Mustang you are going to need a Turbosmart Kompact Shortie Blow Off Valve that can handle the extra pressure - up to 30psi.

      Recirculating Blow Off Valve. Turbosmart designed their BOV to be a fully recirculating valve. This means all the excess pressure is routed back into the vehicle's intake. Providing quieter operation, this Blow Off Valve is ideal for those looking for more power without attracting unwanted attention.

      Vacuum Activated. Unlike the factory Ford blow-off valve that is electronically controlled by the ECU, the Turbosmart Kompact Shortie Blow Off Valve is mechanically operated by vacuum for consistent manifold pressure that helps keep your turbo spooled for better throttle response.

      Quality Construction. Constructed from aircraft grade aluminum alloy for durability and strength, this Turbosmart Kompact Shortie Blow Off Valve features a light-weight brass/aluminum two-piece piston, which is then perfectly matched with precision engineered springs allowing for razor sharp valve response.

      Application. The Turbosmart Kompact Shortie Recirculating Blow Off Valve is designed for use on all 2015-2020 EcoBoost Mustang's equipped with the turbocharged 2.3L Inline 4-cylinder engine.

      Technical Note. This Blow Off Valve is not legal for use in California or other states adopting California emission standards.

        Great investment!!!

        At first I bought I thinking it was a blowoff and that it was going to sound loud but then when I put it on It was a low sound but after like 2 days it got louder and sounds great and I love it.

        Turbosmart BOV

        Amazing product and easy to install. Completely eliminates all turbo lag, makes a stock EcoBoost feel very quick. Definitely recommend this product! Functions much better than the OEM part. Also, on a previous review I saw that someone said their gauge didn't work after install; I have a performance package and my boost gauge works perfectly!

        4 2018 EcoBoost - Kory Installation Time: Afternoon

        Almost Stock Sounding... kind of disappointing

        Was kind of a pain to install because of the instructions being low quality, and in black and white. Other than that, about an hour install, and it sounds almost identical to the stock BOV.. not worth it in my opinion

        I liked the BOV the sound was cool, I went with it to keep it a recirculating system. I didn't like the fact that I had to alter factory parts and it also made a ticking noise I didn't like. I swapped it out for an electric turbosmart plug and play

        5 2015 EcoBoost - AndresV Installation Time: Shop Install Installation Cost: 0-$100


        Recently upgraded to Cobb Stage 3 (Cobb intake, cobb intercooler, stainless work downpipe, borla atak, turbosmart iwg 10psi and the recirculating bov). I am not particularly a fan of the sound but knew that to keep my turbo safe I needed the upgraded valve and it might be one of the best purchases ive made for my Eco. It really only sounds noticeable when downshifting hard into second or aggressive letting off the throttle when its floored. The volume is perfect for anyone who wants to keep their turbo safe and does not want the sound of the blow off valve. Great product.

        5 2017 EcoBoost - john950 Installation Time: Less than 1 Hour

        easy to install havent tested performance yet

        Installed last week while recovering from surgery, so cant test yet to check performance gains. After Mustang has a gauge to check boost and vacuum, however only vac registered I suspect due to the removal of the electronic connection as this is now a mechanical device. Followed the easy install instructions and found that even with a Strut tower brace I was able to remove the engine cover. There is supposed to be a way to tell where the valve is positioned to make final adjustment but I found none only instructions to rotate valve to desired setting, not very specific. Well built product with everything needed and I look forward to being able to drive and check out the performance gains.

        Kompact turbosmart installation

        The product seems pretty heavy duty.... and quick to install. It would have been easier if they could have provided pictures on how to install the product, I am more of a picture guy. Thanks,

        Took a while to get it straight.

        My Blow Off Valve arrived with some missing hardware so I couldn't install it right away. AM got replacement hardware to me asap. After installation I immediately threw a CEL. Code reader said "Turbocharger/Supercharger Bypass Valve Control Circuit High". AM got me a new Turbosmart BOV CEL Defender Plug asap and now I'm good to go. Much better material and higher boost capable.
