Review & Installation Video

Justin: What's up, guys? Working on another build here today in the shop. This time it's Bama tuning technician Justin and his beautiful '13 GT behind me here. Now, Justin, tell us a little bit about your experience and some of the mods going on with the car. Justin: So far it's got some JBA long tube headers, off-road exhaust, 4.10 gears and a Bama tune. Currently the car runs about 12.30s at the track on street tires. Justin: We've got some parts that should definitely help you out with that today. And, guys, we're going to be getting to work on his car very soon. But of course, if you want to see more of these builds, you should know what to do by now. Be sure to subscribe to our YouTube channel, American Muscle Videos, for more of this great Mustang content. But now, ready to get to work, brother? Justin: Absolutely. Justin: All right. Let's do it. Well, guys, here it is. We're doing the Cobra Jet intake manifold on Justin's GT along with the big monoblade throttle body, some parts, again, I have some familiarity with. These parts absolutely rock. And Justin, I know you're stoked about getting these things on. What are you most looking forward to? Justin: Last time I went out to the track, my car really fell short, the high RPMs. I couldn't make it through the traps in fourth gear without having to push the clutch in and roll through. I'm looking forward to being able to just blast it all the way through, see if it can pick up a little bit of top end power as well. Justin: Absolutely. I definitely saw some good gains, and I'm sure with your long tubes. So I'm guessing gains should be huge with this thing. Any expectations numbers-wise? Justin: Hopefully between 4.30 to 4.40. Anywhere in there I'll be super happy. Host: Fantastic. Now obviously, guys, the install itself really isn't that bad. I mean the only part that really will give you any extra work is re-pinning the ECU or the throttle body harness here, since we are switching to a GT 500 style throttle body. It's really a piece of cake though, once you get a re-pinning tool or something like that, and Justin made short work of that. So we're going to keep working on this thing and get it buttoned up, but, Justin, white GT, Cobra Jet set-up, did we just become best friends? Justin: I think so. Justin: All right. All right guys. So Justin and I are just finishing off installing the last piece of the puzzle here today. That's the Ford Racing cold air intake that, of course, is designed to work with the Cobra Jet set-up. It looks awesome under the hood, but now it's time to make some power. So we're going to move this thing over to the Dynojet. Justin and his team at Bama Performance are going to write a tune for this thing, and it's time to rock and roll. Are you ready man? Justin: Let's do it. Justin: Well, guys, Justin just finished making up a few runs here with his 2013 GT with the Cobra Jet set-up installed. It certainly sounded nasty, and I think the results are speaking for themselves. The car is now making 433 horsepower, 381 pound-feet of torque, a nice little gain of 30 peak horsepower over his baseline numbers, and gains of as much as 42 horsepower, 25 pound-feet of torque under the curve. A lot of those gains coming in the top end. You got to like what you see, right? Justin: Absolutely. Justin: Nice. Justin: I think the upper RPM range is going to get me through the traps the way I want. I can stay in fourth gear instead of trying to shift to fifth, and the up top power is definitely an added plus. Justin: Absolutely. I think a lot of people should know this about the Cobra Jet set-up. I mean it's really a win-win. You're getting all of those big top-end gains, but unlike the boss manifold, you're not sacrificing a ton of low-end power. Speak to me a little bit about the tuning process. I saw you and Paul out here working on the thing. Justin: Paul and I spent a lot of time developing this tune specifically for this car with this combination. The monoblade throttle body sometimes gives some drivability issues, so we spent a lot of time getting that smoothed out. It's got a nice smooth idle. The throttle action is very smooth and progressive. There's no choppiness to it. Justin: So very nice drivability is what you're telling me, then? Justin: Absolutely. Justin: It think there's really one way to test drivability. It's not really something you can show on the dyno. So what do you say? We get this thing unstrapped. We hit the streets and see how it does? Justin: Let's do it. Justin: All right. So we're out in Justin's car here, his 2013 GT with the Cobra Jet set-up. Now full disclosure, guys, it's the middle of the winter time here in the Northeast. It's 20 degrees outside, salt and ice all over the road, so obviously we won't be doing any gnarly 1st through 4th top end pulls today. But we're just really getting the feel of the drivability and so far, Justin, what's your impression? Justin: I think it's smooth as butter. It's everything I hoped for, maybe a little bit more than I even expected. Justin: Yeah. You said pulling out of the parking lot it's almost even better than your stock set-up, correct? Justin: Yes, absolutely. Like you said, we can't really go full-throttle pulls, but testing the drivability, it's definitely impressive. Justin: The car sounds good, though, man. I like it from the inside. Justin: It sounds totally different from the inside. Justin: It sounds awesome. Justin: Every body said, "That car's ferociously loud." I'm like, "Yeah, I know. It's awesome." Dude, it's smooth. It really is. Justin: That's awesome, man. Well, I'd say it pulls really hard. I mean that was probably what? Five or six grand, not even? Justin: 5500. Justin: So if you were to crack off a downshift here or there, I mean there's no throttle hang or anything like that? Justin: No. It drops back down to the desired idle almost instantly. Justin: That's always important, too. I know a lot of people get worried with the big monoblades there's going to be a lot of throttle hang, a lot of lag. But you're not seeing any of that? Justin: None of that at all. Justin: It still pulls hard as ever. So there you go, guys. Obviously Justin is stoked on his Cobra Jet set-up, as he should be. The car is making good power, pulling strong, and driving great. Justin: Absolutely. Justin: There you go. So we'll be able to follow Justin when he heads to the track so we can actually see if he's improved on his low 12 second time slips. But in the meantime, for all things Mustang, keep it right here at

More Air for More Power. Your 5.0L coyote V8's stock manifold is designed to perform well at the low end, but it chokes off airflow at the top.

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?


Helpful (6)
  • 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.


Is this only for manual transmission just like the boss intake?


Helpful (1)
  • The Ford Performance Cobra Jet Intake Manifold is applicable with automatic and manual transmissions.


Can it handle forced injection? I am between this and the boss manifold, if I did this I would do the twin 65mm TB and JLT CAI, could this set up handle a twin turbo or would I be better off with the boss manifold?


Helpful (1)
  • Ford racing used this manifold on the twin turbo cobra jet concept, so I'd have to say yes it can handle forced induction


Would size injectors would be best suited for this intake on a stock 2012 GT with a Flowmaster Outlaw series cat back exhaust.


Helpful (0)
  • The Ford Performance Cobra Jet Intake Manifold would not necessitate new injectors, unless the remainder of the setup requires larger injectors. We typically do not recommend this intake without at least long tube headers, as this manifold is designed for high RPM (Peak power of 7750rpm) and gives up low RPM power for this. This is ideal for track cars, and heavily modified cars.

I read somewhere that the throttle body on the oval cobra jet needs to be calibrated where to I get details on how to do this?


Helpful (0)
  • This intake manifold itself would need to get calibrated not only just the throttle body. Bama Performance offers handheld tuners with custom tunes for the optimum performance.


For a first time mod on my 5.0 L GT which intake manifold would you recommend the Cobra Jet or the Boss 302? And Why? They seem very similar.


Helpful (0)
  • 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.

    I was very indecisive about buying this for my 2012 GT but decided why not . It is hands down one of the best upgrades you can possibly do to you're mustang. The power gains are immediately noticeable and the sound difference makes it so much more throaty and the crackles and pops are off the charts. Do not wait to buy this upgrade just do it.

    My experience was that there was a up to a 10 loss in torque compared to the stock manifold with CAI, tune and long tube headers in the 3,000-5,400 rpm range (-33 lb ft @ 4,300 rpm). There was an increase above 5,400, but nothing to write home about until you get over 7,000 rpm where the hp stays high and the torque doesn't drop as fast. Now if you're drag racing or probably even road racing, the torque loss won't matter. You won't be seeing rpm's that low except when you launch or leave the pits. Since you'll be needing a tune for this, you can just raise the rev limit, pick the right rear axle ratio and shift at higher rpm. For the street, though, if you have the stock manifold don't waste your money on this or the Boss manifold . You'll gain more from a good CAI, tune and headers. They don't have the option in Driving style for what I do besides daily drive, which is SCCA Solo.

    Great look and sound

    I wouldn't expect a thrown back in your seat difference with this but it definitely Pulls harder on the top end. Ive got the twin 65mm TB and the Ford CJ CAI along with a tune from Jon Lund. With off road exhaust and an Axleback the car is an absolute animal and a blast to drive. The intake makes the engine sound much different, in a good way. Takes less than 2 hours for install and worth it. Definitely go this route over the boss manifold. Us coyote owners can't spare any lost torque.

    Bad Quality control

    Well how can I give this part a good review if i haven't been able to install it after i am missing 2 very important bolts that actially tight up the intake manifold to the motor and without those(M6x45mm) bolts i am pretty much in the air until either i find them somwhere out there or AM gets the manifold back in stock otherwise i am screwed. On the other hand i hope this manifold its awesome whenever i get to install it in the near future......hopefully.

    Instant power

    This was a great buy. I had the boss intake and decided I would see what this was about. Pretty simple swap out of intakes I would say it'd take 2 hours to get done. Came with everything needed although the change in wiring harnesses can be a pain. In the end you feel the power gain instantly. It starts to push you back in your seat around 2k. If you're debating this vs the boss intake definitely go with this one you won't have any regrets

    Picks up later in the rpm band.

    On a bama 93 octane tune with the monoblade throttle body and JLT intake. The intake sounds awesome when tapping throttle. However, gains aren't really noticeable until after 4k rpms and up. I bet with a good dyno tune or just an email tune from another reputable tuner I'll be able to squeeze a little more power out of this setup. I will say it looks friggin awesome under the hood!

    Worth EVERY $$

    Let me start off by saying that I had priced this setup for over a year, and NO one can beat American Muscle's price. Do NOT hesitate to purchase this modification, because each day that you wait, you are only cheating yourself out of good ol' quality time with the 'Stang. Install is a breeze and can be done as quickly as an afternoon (like me) with moderate mechanical knowledge. The power is there without a doubt, and the way it pulls is amazing- even past original redline. Don't wait. Don't hesitate. Buy this next mod now!

    The truth!!!

    A few tips to start, with a good set of small picks the wiring takes minutes and is just about fool proof. swapping the coolant crossover pipe, you will lose some coolant, kit does not come with throttle body to intake bolts?? WHY?? also stock ones dont work. also you need to buy the boss 302 install kit for some misc evap solenoid, also do yourself a favor buy an oil catch can from JLT for the passenger side, after about 100 miles the intake had a little oil blow by in it easy fix. I have the whole cobra set up and hooker 3 inch xpipe back with muff deletes, stock headers, my car only made 404 RWHP on the dyno with my BAMA tune....Seems a little low to me. The car ran awful at first , would stall, had no throttle response, and really bad throttle hang coming off throttle, and car would stall. I contacted BAMA great customer service btw, tried this and that with no luck, then it randomly fixed itself....? runs great now no complaints, intake whistles under light acceleration. worth the 2500 bucks, (intake,TB, CAI, tuner, install kit, initial tune)
