    Review & Install Video

    Hey, guys. Adam here with americanmuscle.com. And today, we're taking a closer look at, installing and listening to the CNL Bypass Valve Adapter available for the 2015 and newer EcoBoosts. Now if you're the owner of that four-banger turbo EcoBoost, it might be in the market for something that's gonna make your S550 sound a little bit more aggressive in the realm of turbo sound by converting your factory bypass valve into essentially a blow-off valve. This is gonna give you that crisp release of the excess boost out into the atmosphere that we all love from turbo vehicles. Now let me explain exactly what this is gonna do. So from the factory, your EcoBoost has what's known as a bypass valve, very typical for factory vehicles with the turbo. Now the bypass valve's job is to re-circulate all of the excess boost, the unused boost, back into the system which prevents you from getting that turbo sound that we all love, the blow-off. Now this particular item here converts that into the blow-off valve by adapting itself, placing itself in between the bypass valve and the charge pipe. What this is gonna do is reroute that excess boost back into the atmosphere instead of back into the system. So instead of re-circulating, it's gonna be atmospheric. Now the atmospheric sound is that awesome pssh that we all know and love, right? So this is gonna give you again that nice crisp sound of all of the excess boost getting pushed out into the atmosphere instead of being re-circulated into this system. Now the cool thing about this is that it's actually a lot more affordable than an actual blow-off valve. Now this one comes in right around 70 bucks and it's made of a CNC machined billet aluminum, so it's made to be a perfect fit to your factory bypass valve and your factory charge pipe. Now one of the big benefits of the bypass valve adapter is that it does not require a tune so you can throw it right onto your factory bypass valve and not have to worry about picking up a custom tune to make it work. If you plan on upgrading either one of those items, you're not gonna be able to use this, this is just to be used with the factory components. If you plan on upgrading your EcoBoost, getting it tuned or even upgrading your charge pipe, you'll probably want to look into an actual blow-off valve instead of this bypass valve adapter to reap the benefits of the blow-off valve. So this guy is strictly for the stock or even mildly modified EcoBoosts. Now the bypass valve adapter from CNL comes in right around 70 bucks and if you compare that to an actual blow-off valve that costs about 250 or even more dollars, this is way more affordable. Now it's available in the black finish that I have here in the billet aluminum but it's also available in the aluminized finish if you're looking to get under the hood a little bit more contrast. This personally I think blends in a lot better under the hood, it doesn't look like an aftermarket part when it's installed but if you're looking to get it to pop a little more, check out the aluminized finish. Now this guy is gonna get a very simple one out of three wrenches on our difficulty meter here, anybody can tackle this in the driveway at home. I'm gonna walk you through every step of the process here from start to finish. What do you say we get started? Tools used in this install include a quarter-inch ratchet, a variety of different size extensions and a three-sixteenths hex socket or an Allen key. All right, now before we get started, I first want to point out where we're going. So if you look right at your coolant reservoir, directly below that, right here at the end of my extension here, this is your factory bypass valve. There are three Allen bolts or hex bolts bolting this guy onto your factory charge pipe. So what we're gonna do is take a three-sixteenths socket and remove these guys. I'm using a couple of extensions just to make it easier for you guys to see so my hand's not in the way, but first what I want to do is get this harness a little bit clear. So you can see the harness is actually connecting to the bypass valve, it's also connected to a couple of studs up here, I'm just gonna pop these plastic clips off and just move this harness out of the way so it's easier to see. So I'll just put this guy up here up and out of the way, just give a little more access. I'm gonna use my extensions and my three-sixteenths socket to remove these three bolts. All right, I'm gonna break all three of them loose and then should be a lot easier. All right, so with them loose, I'm gonna take my ratchet off and just use the extension to back these bolts out. I'm gonna put my hand underneath so it doesn't fall out, there you go. That's one, two more to go. All right, so this guy's up and out of the way. Now you really don't have to unclip this harness, we're going to just so I can show you guys, but you will just pinch and pull directly back. So I'm gonna pull this guy out and let's talk about the difference. All right, so just very quickly we have our factory bypass valve here in my right hand, our CNL bypass valve adapter in my left. Now if you were to pick up an aftermarket blow-off valve, you'd be completely replacing this entire unit. The blow-off valve is just a totally different unit, you'd take this guy out, set it aside, and install the blow-off valve in its place. Now because we're reusing this, the bypass valve adapter is gonna adapt right on to the back end here in between the bypass valve and the charge pipe. This unit here and its specifically formulated and cut holes is gonna re-circulate or redirect that air into the atmosphere instead of back into the system. Now what we're gonna have to do is line up the holes on your bypass valve to the adapter, and it really only goes in one way. So if the holes don't line up, you're just gonna keep rotating it until they do. And then we're gonna use the three longer hex screws or hex bolts included in the kit to adapt it. So what we're gonna do is grab the hardware, put those through, line it up, we'll tighten everything down with just the socket and extension, and then we'll tighten it all back up. So let's do that. All right, now before we get started, couple of things we want to make note of. Again, I already talked about making sure that the holes are lined up, you want to make sure you're doing that before you start, just so you don't have to fidget with it down there. Secondly, the factory bypass valve has this rubber O-ring. If it's in bad condition, you might want to replace that guy. You just want to make sure you're preventing any boost leaks and the same thing goes with the CNL. Now the CNL one comes with brand new dual rubber O-rings, you want to make sure they're seated properly. Underneath that seal is a little indent port, make sure it's seated properly. It's already seated there right out of the box but things get shuffled around. If it's not seated, just double-check. You really don't want to risk any boost leaks, throwing a check engine light or anything like that. So what we're gonna do, just swivel this guy around, make sure we've got it aligned where we want it. We're gonna take the longer screws. I'm gonna put one through just to hold it in place. Let's grab this harness and plug it in and then begin this process. We just want to get one started to hold it in its place. All right, so once you have all of them in place, just go back with your three-sixteenths socket or Allen key and tighten these guys down. There you have it. Well, guys, that's gonna wrap this one up here. So if you want to pick up the CNL bypass valve adapter, it's available in black that I have here, and also an aluminum finish, if you're looking to give it a little more contrast under the hood. You can pick them up 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 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.

        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.

            Great sound

            This was the first mod for my mustang, and I do not regret it. This provides that amazing sound of a blow off valve for cheaper. This I definitely a head Turner and it really makes your car sound good. Took about 10 min to install, because one of the bolts is hard to get to.

            Sounds amazing. Will attract attention.

            I installed this couple weeks back. Took around an hour because this is designed only for the 2015 to 2017 ecoboost models. I own a 2018 mustang ecoboost manual. In order to properly install this, you would have to remove the coolant reservoir and more importantly the air intake piping which slightly blocks the area where you install this bypass valve. However, that being said, with slight pressure on to the intake piping you can just barely shove it aside and squeeze your hand through and basically use a 5mm hex key to remove the three screws and install this valve. It was a pain and I wish they were clear that this was "designed" to be installed for the 2015-2017 models only. It even says so in the instructions that came with the product lol. Now for the sound. This sounds amazing. It will attract crowds. Basically sounds like ennng tssssh the moment you release the throttle. It's very fun I'll be honest. For the price this made my mustang that much more fun to drive- i'm not sure why Ford didn't make this stock. Now i have a manual transmission so I dont get the whistling sounds that others have stated on the automatics in the highway, in fact this sounds great at low and high speeds. The sound is even better with a muffler and resonator delete. I would definitely recommend but it should be clear that this was designed for 2015-2017 mustang ecoboosts, with a little leway for 2018 if you know what you're doing.

            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.
