    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 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.

        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.

            ALL THE PSH!

            If you got a Mustang Ecoboost and have been wanting that distinct turbo sound this is the route to go! It took about 30 minutes to put on and it was super easy to do. The only complaint I have is on the highway if the turbo doesn't fully spool (only 1 or 2 psi) it sounds like you are leaking air.

            Does what it’s suppose to do

            It makes a loud pshh after letting off throttle, only con I would say is that I noticed a little delay in the turbo, but nothing to bad.

            I put this on my wifes 18 ecoboost when she wasn,t looking and what a laugh. the car is loud with full exhaust and intake done but the pishhhhh when she let off was great she thought there was a truck next to her. Our grandson says it needs smoke stacks and an airhorn lol he is 6. But she actually likes it now.

            Love it...mostly.

            Installation was fairly easy, other than the screws being a bit hard to get to in some areas. Really enjoying it so far, have had it on for nearly 3 weeks now and it sounds amazing. Pulling up a to a car meet and having that turbo blow off sound turns heads instantly. The only drawback I personally have is it gets attention even when I don't need it (like grocery store runs) but other than that it's an amazing, cost efficient way to get that turbo blow off sound that many people are after.

            It turns you ecoboost into a BOV and give you that blowoff sound. Easier to install if you remove the cold air intake first.

            Pretty cool

            Install is very simple.. just 3 bolts. Somewhat of a pain to get to. Took about 20 minutes if that. Dosent exactly sound like a blow off valve but it does catch people's attention and when paired with a exhaust it dosent sound to bad in my opinion. Worth the money if your looking for something different
