    Review & Install Video

    Distinctive Turbo Sound. The 2015-2020 EcoBoost Mustangs are equipped with an electrically control bypass valve (BPV) which does a great job controlling boost, however it does not make that signature turbo sound that hardcore boost fanatics love. By installing a C&L Bypass Valve Adapter the unused pressurized air will now vent to the atmosphere making that distinct sound all turbo owners know and love.

    Billet Aluminum Construction. Proudly made in the USA from high grade billet aluminum, this C&L Bypass Valve Adapter has been precisely CNC-machined for a perfect OEM style fit. The BPV Adapter is then completed in a mild polished finish for impressive under hood styling.

    Easy Bolt-On Installation. C&L's Bypass Valve Adapter simply mounts between the factory charge pipe and the stock Bypass valve. C&L includes the necessary hardware needed for an easy bolt-on installation that takes less then an hour.

    Application. This C&L Bypass Valve Adapter is designed for use on 2015 to 2020 EcoBoost Mustangs equipped with the turbocharged 2.3L Inline 4-cylinder engine, that are still running the OEM bypass valve/solenoid. No tune is required for operation.

        5 Top Rated Questions

        Will this BVA hurt the car or turbo in any way? Does this part limit the amount of boost sent to the engine since it is always open?

        • This will not hurt the turbo in any way, otherwise we wouldn't offer it. This also would not limit your application any more than your stock setup.

        this bypass does not require a tune? can it be install to an ecobooost that does not have an intercooler installed? will it increase the performance of the ecoboost? comparing to a full blow off valve

        • There is no tune required to use this. We would suggest installing an intercooler along with this. You will likely see more of a performance increase with a blow off valve instead of this.

        The Review Installation Video is good, but you really need a video of the C L Bypass Valve Adapter doing it's job. I for one, would like to hear the results, before I take the plunge. Is there such a video somewhere?

        Legal in California?

        • The C&L Bypass Valve Adapter is currently legal in California yes.

        So if I already have a new bov installed will this pretty much be pointless to me? Or will it still make a difference? Wish I'd seen this before would've saved a lot of money,but it was worth it.

        • The C&L Bypass Valve Adapter in Aluminum will be specific to the fitment with the factory BPV. This will not properly fit with an aftermarket BOV installed.

        Will this void any type of warranty 1 answer
        Would this benefit from a new tune? Since it is changing the air that flows into the system I can't help wondering if the ECU would really be better off knowing about it. Or do the sensors in the system monitor things so accurately no change is required or beneficial? 1 answer

            Easy install! Sounds amazing

            Was wary after seeing reviews regarding constant hissing. I’m not sure why other people have that problem but for me it’s absolutely amazing sound. Definitely turns heads and makes the mustang sound crazy aggressive. Easy install, took about 20 minutes total. Probably would be less, but my big roush intake was in the way. I couldn’t be happier with this part. Worth the money by far.

            Love it

            I love it. Saw some people post about a whistle at highway speeds. But it's very light and u can just let off for 1 second and back on and it will stop.

            C L Bypass

            The CandL bypass valve sounds great. Helps release all of the extra air from the turbo. Whistle noise is not super loud but also not low. Installation process was easy took about 10-15 minutes.

            Remove water hose and if you need to unscrew the coolant before installation. It’ll make it easier to reach the bottom screw which to me was the hardest to reach. Other then that, I love the sound it makes. I also noticed a slight gain in mpg by 1.2. I also noticed my acceleration picks up more now that the air that’s not being used is being released. Therefore letting new air come in, instead of it being reused or “trapped”. I recommend this to any Ecobeast owner out there that doesn’t feel like dropping $200 on a turbosmart.

            Bypass Valve Adapter

            I had loved it when I first installed it, as I started driving I noticed on the acceleration it makes a weird noise and noticed I am losing horsepower. It’s a fun little mod but gets annoying after awhile.

            Install was a breeze.

            The CandL Bypass Valve Adapter was a piece of cake to install, I did it on my driveway in about 15 minutes, and most of that was looking for my tools. Does as advertised, makes that classic turbos "whoosh" sound we all love. Highly recommend.
