    Review & Install Video

    Hey, guys, Stephanie with americanmuscle.com, here with a review of the C&L bypass valve adapter for 2015 and newer EcoBoost Mustangs.You're gonna want to check out the C&L bypass valve if you still have the OEM bypass valve or solenoid, but you aren't in love with the lack of sound that it provides and you'd much rather have the sound that a blow-off valve produces, but you aren't looking to spend blow-off valve money. You're looking at having to drop over $250 for a true blow-off valve, but the C&L bypass adapter here can get you the same sound effect for about $200 less.Being a factory turbo car, the EcoBoost doesn't come from the factory with a blow-off valve, as everyone in the world of aftermarket turbo life knows it. The car has a bypass valve that doesn't allow the unused air to vent hemispherically, which means you don't get the blow-off valve noise when you build boost and let off the throttle quickly. The C&L adapter will turn the factory bypass valve into a blow-off valve and allow the unused air to vent into the atmosphere, which in turn gives you that crisp release of the pressurized air. What's nice about this is that it's inexpensive when you compare it to the cost of a blow-off valve. It's very easy to install, and it does not require a tune. You aren't changing much here. You're just rerouting the excess air that builds up and isn't used when you spool the turbo and let off the throttle before all that boost is used.The bypass valve itself is made from billet aluminum and it's CNC machined, so it will have a good fit. This one here is anodized black, but C&L does have one that has a mod polished finish for those of you that don't want black.When it comes to price, you're looking at spending about $70 for this bypass valve. To put that in perspective, you can plan on spending $200-plus for a true blow-off valve, so it's safe to say that if you're just looking for the noise, this is a much more budget-friendly way to achieve it.Now, I will say that if you plan on modding your EcoBoost, going with a tune, upping your boost, and then eventually you might be looking at upgrading your charge piping, if you're looking at upgrading your charge piping, then you might consider going with a true blow-off valve instead because you're gonna need to relocate and upgrade the blow-off valve anyways. The stock bypass valve won't be able to be used with the upgraded charge piping.As far as the install goes, it's a very easy install. It should take about a half an hour's time. It's a one out of three wrenches on the difficulty meter, and you'll need a five-millimeter Allen key as far as tools to get the job done. You need to get to the stock valve on the factory charge piping, disconnect the wiring harness, and remove the bypass valve, just a few five-millimeter Allen head screws. The C&L adapter will be placed between the stock bypass valve and the charge pipe. You can then reinstall the bypass valve with the adapter using the longer bolts that are provided for you. Once they're bolted down, you can just reconnect the wiring harness.Wrapping things up here with the C&L bypass valve adapter, this adapter will vent the unused pressurized air to the atmosphere, which will give the distinct turbo blow-off noise that most turbo people want. It's very easy to install, it doesn't require a tune, and you can check it out more online, right here at americanmuscle.com.

    Distinctive Turbo Sound. The turbocharged EcoBoost Mustang is a great car, but the one thing that hits a sour note with hardcore boost fanatics is the lack of that signature turbo sound. 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 black anodized finish for aggressive 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 2018 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.

    Since its running out into the atmosphere, will it make my car run rich? Many online forums say it can make ur car run rich, which leads to it smelling, bad mpg, along with fouling the plugs and cats. I already ordered it but now fear installing it.

    • Using the C&L Bypass Valve Adapter can cause a rich condition on shifts if not used with a tube.

    Hi, can you please tell me if the C L bypass valve adapter will work on the 2018 Mustang Ecoboot 2.3 L engine? The range seems to be 2015 - 2017. Was there a change to the 2018 model that prevents its installation and use?

    • The C&L Bypass Valve Adapter has not yet been tested with a 2018 Model to confirm fitment. Once fitment has been confirmed, we will update the product page.

    do i need any other parts in order to install this blow off or that's all i need to buy

    • The C&L Bypass Valve Adapter will allow your factory bypass valve to vent to atmosphere, rather than recirculate, allowing it to work as a blow off valve. All required components are included.

    Could installing this cause a cylinder misfire?? I bought and put this part on my 2016 Ecoboost about a year ago and only a few days ago did I have my Check Engine light come on (for a cylinder 3 misfire). After taking it to the dealership where I bought my car brand-new just 2 years ago, the only thing the mechanic could say was that this was causing the problem. So, is that possible? Because I'd really like to put it back on!

    • The C&L Bypass Valve Adapter would not cause a missfire, especially not one limited to just 1 cylinder. You may experience a slight lean condition when using a blow off valve instead of a bypass valve, however this is not typical on the Ecoboost Mustangs.

    Will this cause my mustang to lose any power? Also, will the stock boost gauge still work?

    • This Bypass Valve Adapter will not affect the power on your Mustang at all. The stock boost gauge will still work as well.

      Great sound

      I always wanted a turbo car, after I got my mustang I was going to get a BOV for it, but this pretty much gives the same sound for a cheaper price. Install took about 30 minutes cuz I got big hands, but its pretty easy. Comes with clear instructions too.

      Fantastic Results. Easy install.

      The product itself works amazingly. Instant notice in blow off valve sound. Really enjoyed it. Just wasn’t for me. The sound goes off quite frequently due to the low RPM spool of the turbo. It’s great otherwise.

      Great Product

      The CandL Bypass Valve adapter is a great choice if you’re looking for the classic blow-off turbo car sound but aren’t looking to spend an arm and leg on a true blow-off valve and aftermarket charge piping, etc. The installation was very simple. I ended up having to unbolt the coolant reservoir tank and set that aside to gain more clearance with my allen wrench, but other than that, quick and clean.

      Terrible

      This thing was easy to install, but that was the only thing good about it. First it caused fluttering of the throttle and then there was the bad gas mileage I used to get 18mpg city with the stock setup and 22mpg with the turbosmart BOV, this combo with the stock bypass valve dropped me down to 5mpg.

      simple, works, sounds great

      Once installed, this valve produces one of the loudest (but clean and smooth) turbo sounds, somewhat like a truck air brake but not that loud. It produces a single PSHH sound, not a swirling turbo sound like some other vehicle setups, which isn't good or bad, just a preference thing worth mentioning. Hope this helps.
