    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 2019 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.

      Bought it for my 2018 very solid construction good quality. You hear it any time you let off the throttle and if you are in Cruze control sometimes. Little bit tricky to get the last bolt in and out.

      Sound

      It sounds great. A lot better than most actual aftermarket blow off valves. Super easy install as well. It took me about half an hour to get on. It would’ve taken me 10 minutes of I hadn’t have dropped a bolt

      10/10 would buy again

      Took me about an hour to install only because I dropped my tool in the snow and had a hard time finding. It’s a very tight fit trying to unscrew and attach your new bolts but after all that work and effort it was definitely worth the time. Would recommend buying this product because it sounds awesome especially if u have a aftermarket exhaust system on your ecoboost.

      Cool Sound, Gets annoying eventually..

      Super easy to install and fun mod, has a cool sound but can get annoying. At highway speeds the boost vacuum with open and you can hear the blow off leaking through the A/C sound. 10 speed makes it wose than in the 6 in the 2017 I had. “Veroom, veroom, chhhh chhh, veroom, chhh” it can be annoying. Going to be adding a recirculating BOV.
