Hey everybody, I'm Justin with americanmuscle.com, and welcome to my detailed review on the Ford Performance Cobra Jet Intake Manifold, fitting your 2011 through 2014 GT and Boss Mustang. So this review's gonna cover my thoughts on the Cobra Jet Intake Manifold as an owner. We'll talk about some of the benefits you can expect when bolting everything up. And then finally, we'll cover some of the meat and potatoes of the installation. And as you might imagine, there are a few steps involved when getting this bad boy in place, but nevertheless, it's still not that bad. So I'm going two out of three wrenches on the difficulty meter. And we will have some more detail for you later on.Now, the Cobra Jet Manifold that we have in this video is going to be a great choice for both Boss and GT owners out there looking to maximize their naturally aspirated performance or even your forced induction performance by using an extremely free-flowing manifold like this option here from Ford Performance. Now this thing will effectively raise your peak power in the upper RPM range, but without taking a huge hit to your low-end torque like some other manifold options on the site. Perspective buyers will want to keep in mind the fact that you will need to change out your throttle body in addition to your intake, along with factoring in some custom tuning. The Cobra Jet Manifold is obviously a product that's near and dear to my heart, as I have had this thing installed on my personal GT for a couple of years now. And I absolutely love it. I have no complaints whatsoever. Totally transformed the way the car behaved, and for the better. Now I've always thought of this thing as the perfect compliment to the full array of bolt-ons, of course. But even for owners out there who might wanna maybe do long tubes but don't wanna mess with the emissions or cats, or maybe are afraid of long tubes from an installation standpoint, this is a good alternative. It's gonna cost you roughly the same amount, but at the same time the install's gonna be a lot easier and deliver similar gains.So let's talk about this manifold a little bit more. Now this thing was developed for the 2013 Cobra Jet drag car, the naturally aspirated version, for maximum horsepower in the upper RPM range, right? Makes sense. That's where drag cars typically operate. Now if you look at this thing at first, and if you're like me and thinking old school muscle car or dragster, you're thinking tunnel ram intake, right? Because it looks very similar. In fact, if we had a tunnel ram on the table, they'd look very identical. Long straight runners here, and they're both designed for similar goals, delivering that high horsepower in the upper RPM range.So what does that mean for you guys watching at home? Well, if you're looking to bolt this thing up to your Coyote Power GT or your Boss 302 and lug around town between 2,000 RPM and 5,000 RPM expecting to feel a big difference, you're gonna be really disappointed because that's really not what this thing is all about. Instead you have to ring this sucker out to the moon to really feel a difference. Ford Performance designed this thing to make peak power at 7,750 RPM, and the dyno graph I got for my car really reflects that. Now the factory manifold tends to run out of breath right around 5,000 RPM, where this sucker just kept on climbing all the way to my 7,900 RPM rev limiter.So now that you know a little bit more about what the CJ manifold is all about, let's talk about some of the finer details with this thing. It's made from a lightweight composite material, features 635 cubic inches of volume, and has been pressure tested to support 20 plus pounds of boost. And that leads me to my next point. I talked a lot about some of the naturally aspirated benefits when bolting this thing up, well, there's a lotta guys out there running centrifugal blowers or turbo applications who have used this manifold as well with really, really good results.

2012 Mustang GT
I have the Cobra Jet intake on my Pro Charged 2012 Mustang GT auto. Its a Beast with the Pro Charger for sure. The Boss 302 strut bar fits over it just enough with no problems. I had a Bama tune ran good but now and then it stalled out. The Speed Shop I go to put a HP tune in and that is alot better then the Bama for sure. CJ loves to gobble up the air forced into it by the Pro Charger. 10 psi going in to CJ think I will shoot for 4 more psi.Helpful (0)

Installed the CJ Manifold, with JLT INTAKE, and FR 65mm twin throttle body and 47lbs injectors and it made a huge difference in power. Power you can feel throughout each gear, and redlining at 8000.Helpful (25)

Would be 5 stars if...
Bama wasn't so terrible. I get my tunes and the RPM rev limiter is still 7000. Why? It is things like this(not paying ANY close attention to detail) make me tell people to stay far away from these stooges they call tuners. The Mani went on like a dream, the instructions aren't super clear, but the install is easy enough to get through. Even with a 7k redline it pulls HARD! I juiced up the redline to 7600 for now, and i can only imagine how well it will pull when I get the pulse ring on and push it to 7900! What a great mod for these cars, really wakes it up in the 5-8k rpm range.Helpful (22)

If you use this intake manifold as a daily driver you will not be happy. Even with long tube headers and 3:73 gears I loss about 25 ft lbs of torque below 4k RPM. It feels like my car is stock below 4k RPM. Once above it starts to scream and will continue to push you back in your seat till your desired shift. Don't read this wrong! Even in first and second gear the car will still roast the the stock 245/45R19 tires. If your driving normal you will feel the torque loss. But if your racing and keep the engine revved up this intake manifold is a beast.Helpful (39)

Great intake manifold
Really great intake manifold. Replaced my gt350 intake manifold with this cobra jet. Really see and feel the power differenceHelpful (25)

Loads of Air
Nice piece to add if your going max effort naturally aspirated and will keep building on it like cams and full exhaust and so on. I love opening the hood and seeing a different setup from most. It breaths and made the exhaust louder. It all depends on your goals. If your looking for torque and curve cutter stay stock manifold, small easy upgrade go Boss to increase RPM and some power. Cobra Jet for drag, highway racer and max effort builds. AM has delivered all parts I’ve ordered really fast and customer service is great.Helpful (21)
Is this only for manual transmission just like the boss intake?
The Ford Performance Cobra Jet Intake Manifold is applicable with automatic and manual transmissions.
What do the hp/tq numbers look like ? Ive been looking on getting the Boss 302 IM but decided to wait to see what this was all about. will this work with the steeda cai?
Ford Racing (Jesse Kershaw) said that it makes 25 more hp than the Boss intake with no further torque loss. It could work with the MAF and filter from the Steeda but you will need to fab an oval inlet. The CJ racecar uses a 123mm FRPP MAF and that would be optimal with the intake and mono blade TB.
Well this fit an automatic as it says "w/manual transmission "
The Ford Performance Cobra Jet Intake Manifold will only fit the 15'-18' Mustang GT equipped with a manual transmission.
This is a definite future mod for me. But right now I'm looking at tower braces Is there a tower brace that will clear this?
The Boss 302 tower brace will fit with this setup.
Covers? Will the Boss 302 side covers work with this intake, or are there an covers designed like the Boss 302 intake covers for this intake?
Yes those side covers will work perfectly with this manifold
The Ford Performance Cobra Jet Intake Manifold (11-14 5.0L) will not have clearance issues when used in conjunction with the BMC Black Mamba II Hood - Carbon Fiber (10-12 GT, V6) item #98702 (http://www.americanmuscle.com/bmc-mambaii-cf-hood-1012gtv6.html). The Ford Performance Cobra Jet Intake Manifold will also have clearance with a strut tower brace.
Ford Racing claims 25 more peak hp and no torque loss in the curve compared Boss intake. I am EAGERLY anticipating some real world tests showing results with various combinations of heads,cams and headers.
Ford is claiming 25 peak HP and no torque loss in the curve, I have been holding out on buying a Boss intake ever since I first saw the CJ intake last summer. I would recommend that you hold out for some real world tests results on this intake in the next month or two and see what the gains, pros and cons of the intake are as well, the price of the intake should go down just like the boss did once it proliferates the market.
There is a vent tube going to the air intake that is different on the automatic cars that this kit does not have provisions for. Some may have made it work with some modifications, but nothing we have tested at this time. This information comes directly from Ford Performance.
The Ford Performance Cobra Jet Intake Manifold will require the correct throttle body, and cold air intake. Additionally you will require a custom tune, and you will need to relocate or delete the evaporative emissions purge valve.
The Ford Performance Cobra Jet Intake Manifold will not work without a tune and we highly do not recommend driving the car with this intake installed with no tune.
The Ford Performance Cobra Jet Intake Manifold (11-14 5.0L) will work well with both the Super Cobra Jet Oval Throttle Body and Twin 65mm Cobra Jet Throttle Body by Ford Performance, it just depends on the application. Such as the Super Cobra Jet oval one is more intended for race purposes.
The Cobra Jet intake manifold is better than the Boss 302 intake manifold. The Cobra Jet will give you better performance in every category over the Boss 302.
This intake is the best for a coyote N/A and yes you'll need a tune in it.
Not sure about ur 04 hood but I installed my strut tower brace on my 14 GT with a couple of washers under the brace with no problems and I have the stock hood on.
