Review & Installation Video

Review & Install Video

Hey guys, Mike Wilson here from Bama custom tuning and, today we’re going to be talking about the Boss 302 intake manifold for the 2011/2012 Mustang GT. With the return of the boss to the Mustang lineup, GT owners now have access to some of the parts that make the boss 302 the most powerful and naturally aspirated Mustang ever. The boss intake is designed with short runners, which increases airflow, horse power and torque at high engine RPM. It’s made of a lightweight composite material, has a smooth black finish, and a modern boss 302 logo to help enhance the under hood appearance of your Mustang. It comes with everything you need to install it, the bolts, the gaskets, everything needed to make it a smooth and easy installation. The boss 302 intake manifold is a tune required part, so for that, we’re going to use a SCT SF3 flash device, with a 93 octane Bama race tune. Now we’re going to make a stock dyno run so we can get a baseline of horse power and torque. The car made 391 horse power, and 366 ft/lbs of torque. Now that we’ve got our baseline horse power and torque numbers, we’re going to install the manifold, which can be done at home in under an hours time using simple hand tools. Now that we’ve installed the boss 302 intake manifold, along with one of our 93 octane custom Bama race tunes, we’re going to make another dyno run and see what our horse power and torque gains are. The car put down 404 horse power and 355 ft/lbs of torque, while picking up 61 horse power and 43 ft/lbs of torque above 7000RPM, while minimizing our losses throughout the mid range. The boss 302 intake manifold is simple to install with hand tools you have at home in under an hours time, and you can pick up 61 horse power and 43 ft/lbs of torque.

Gain Serious HP and TQ. Bolt on up to 61 RWHP and 43 ft.-lbs. of torque to your 2011-2014 5.0 GT Mustang with a Ford Racing BOSS 302 Manifold. We dyno-tested this manifold in-house on our stock 2011 GT with nothing more than a JLT Cold Air Intake, so you can be confident you'll see some real performance gains from this manifold. This manifold is the perfect starting point for your list of power mods, especially if you plan on going forced induction.

More Air for More Top End Power. Your GT's stock intake manifold is designed to perform well at the low end, but it chokes off airflow at the top. This Ford Racing BOSS 302 "runner in the box" Intake Manifold features a short runner design for optimum flow at higher rpm's. This Manifold is ideal for peak engine power and sets the stage for future power mods.

Ready for Forced Induction. Tested for up to 2 bars of pressure, this BOSS 302 Intake Manifold is perfect for your upgraded heads, supercharger, and or cam'ed 4 valve motor. With this type of pressure rating, it can handle the increased air flow and deliver consistent power time and time again.

Calibration Required. Because the BOSS 302 Intake Manifold provides additional power through a different intake design (compared to the stock GT), reprograming of the vehicles computer (ECU) is required for operation. By reprogramming your Mustang's ECU, you will be able to realize the full power potential that this Intake Manifold has to offer.

Race-Quality Construction. Made of a high tech, lightweight composite and finished in stealth black, this manifold lives up to the BOSS 302 name, helping your Pony breathe better while improving under-hood appearance. The Intake Manifold features the modern BOSS 302 logo as well as an optional Ford Racing emblem (not pre-installed).

Bolt-on Installation. The BOSS 302 Intake Manifold was designed to bolt directly onto the heads of your 5.0L Coyote engine. No custom machining or fabrication is necessary for installation. This Manifold is compatible with your GT's stock fuel rails making for an easy swap.

Stock Air Box. If you plan to run your new Ford Racing BOSS 302 Intake Manifold with your GT's stock air box, you will need to purchase the BOSS 302 Intake Manifold Installation Kit which includes all the additional parts necessary for proper installation. Please see options listed above.

BOSS 302 Strut Tower Brace. Seeing that stock and aftermarket strut tower braces designed for the GT will not clear the BOSS Manifold, it's recommended to upgrade to a genuine BOSS strut tower brace. A strut tower brace will help reduce unwanted suspension flex while greatly improving the handling of your Coyote powered GT. Please see options listed above.

Not CARB Certified. This Ford Racing BOSS 302 Intake Manifold is not CARB certified, therefore it is not legal for use in California or any other state adopting California emission standards when installed on a GT model. Not legal for use on pollution controlled motor vehicles; intended for off road use only.

Application. This Ford Racing BOSS 302 Intake Manifold is designed to be a direct fit service replacement for the 2012-2013 BOSS 302 Mustangs, but can also be installed on 2011-2014 GT Mustangs equipped with the Coyote 5.0L 4-Valve Engine. Intake gaskets are included.

Technical Note. When installing this Intake Manifold on a GT, some aftermarket Cold Air Intakes may require modification to the coupler or inlet tube for proper fitment. JLT and C&L Brand Cold Air Intakes will bolt-on with no additional modifications.

Should I get the installation kit? I have a Airaid CAI and the SCT tuner on my automatic 2012 GT, Im planning on also buying the BBK TB not sure yet if 90mm is what I need or 85mm, anyway there are reviewers saying that there is a valve that is no longer needed after the boss 302 is installed and since I don't have the stock CAI all I need is 2ft of fuel line... I want to do this right the first time -no way around- but I don't need half of the kit, why not to have what is only needed for my situation available for sale? I'm sure that a LOT of stangers have aftermarket CAI anyway... I'll be getting x pipes and long tube headers, also three fiber hood and a bunch of other stuff, all AM for sure!!!


  • I got the same setup in my 2011 GT( AirRaid CAI & SCT tumer) I also have a Ford Racing X-pipe and Flowmasters. I did not install a throttle body spacer or a larger throttle body. The Boss 302 intake manifold was alot easier than I anticipated. It is not nessesary to purchase the additional installaion kit. You will need to buy and use the extra 2ft.of fuel line and 2 hose clamps. I fabricated a simlpe aluminum bracket to mount that questionable purge valve. It's Awesome. I Love it!

I am going to order the Boss 302 intake manifold and optional strut tower brace along with the kit to use my stock air box. My question is where am i better off, keeping the stock air box of changing it. For everyone that says change it theres someone who says dont, they say just upgrade the filter in it.


  • The stock air box still has some restriction compared to after market kits. For the best results and highest yields, we would highly recommend an aftermarket intake kit.


Helpful (1)

Will this intake manifold require another retune even tho I'm already running a 93 tune for my headers, high flow cats, Xpipe and airaid intake? Also will my airaid intake still fit properly since this manifold is a bit higher than factory.


  • After this intake manifold is installed, you will need a new tune to properly run with this modification. Also, your Airaid cold air intake will need slight modification to fit with this intake manifold.

Who do I ask or where do I go to get the boss tune? I have the SCT Flash X4 tuner. Is it emailed or how do I get it?


  • Bama Performance can tune for the Boss manifold, however, most performance shops can tune for the manifold as well. If you have an SCT tuner and are enrolled into the Bama Tunes for Life Program, they can tune it for free, by checking out with item 38051 and filling out the tune information sheet. If you are not enrolled into the program, you may enroll by checking out with item 38050, and fillinf out the tune information sheet.

Good day I wanted to know if the intake manifold with the original throttle valve housing works. I have already installed an AEM Brute Force Cold Air Intake - Gunmetal. Does this fit together? Greetings Thomas


  • Hello! The Ford Performance BOSS 302 Intake Manifold is not compatible with all cold air intakes, but it looks like some of our customers were able to get their AEM Brute Force Cold Air Intake to fit.

With the Boss 302 Intake Manifold installed what is the best throttle body to go with?


  • The throttle body that I would suggest would work the best with the Ford Performance BOSS 302 Intake Manifold (11-14 GT) is the BBK 85mm Throttle Body (11-14 GT) item #56145 ( The BBK 85mm Throttle Body is a great upgrade that is able to give you a RWHP of 10-15. Also, no additional tunes would be required when installing the BBK 85mm Throttle Body.

    SWEET, so far

    Just added this Boss 302 to my 2011 Mustang GT/CS. I was very worried my low end performance would degrade from this high RPM performance addition. Since most of the time I am acceleraitng quickly in my automatic, rarely does my RPM stay over 5K RPM where this Boss 302 shows its performance. Does not seemed to have suffered a bit. With the 93 race tune, still accelerates like a champ, hitting each gear of my automatic hard. So far sio good. Install took about two hours, and I am very much a novice. Instructions were pretty good from unisntall to install. Torque wrench - if you only have a foot-lb torque wrench, just divide the 89 inch-lbs by 12 to get it into foot-lbs, ie 7.42 ft-lbs. A very small portion of your torque wrench, but real point is don't over tighten. Only portion I had a little trouble on was the tube that comes with the green cap. On your exsiting 5.0 intake manifold, there is a two pin electronic connector and tube coming off the front of the intake - this is your electronic purge valve and tube that runs all the way back to driver side near the bottom of the fire wall, right above is the brake booster. According to the directions, the purge valve is no longer needed. Well, that means the 2-pin purge valve electronic connector you took off the stock manifold now has no place to go on the BOSS 302 manifold and the purge valve tube that goes back to the driver side at the bottom of the wall has no use. Disconnect the tube there, at the wall, pop a plug on the tube inlet, remove the long purge valve tube that is not needed. Also put a black plug in place of the green plug, unless you prefer the green. Buy (2) 3/8" vaccuum plugs (Pep Boys) to do this. Even though many of the pictures you see here have the tube inlet connected to the purge valve tube, from what I understand, it does not do anything, since their is no longer a purge valve on the new intake. well, I hope that helps someone!

    Boss 302 intake manifold

    By far the best mod ever. My friend installed this for me (he also has the manifold on his 5.0) and it just looks badass, sounds badass, and the power gains are just to sick. They say you lose like 10lbs at low end, but you can barely feel it. The power gains from 4000-7300 are just unreal. The car dyno'd at 428rwhp @ 7300 and my only mods are a boss manifold, jlt carbon fiber CAI, and bama 91 octane race tune. I highly recommend this to anyone with a 2011-2012 5.0!! Be safe and have fun!!

    The Truth About the Boss 302 Intake

    We all have heard the rumors about the Boss 302 Intake. Is the Boss 302 intake worth it?? You want the truth… The Truth is the Boss 302 intake manifold is a Show N Go part. It really depends if the intake is worth it to you, and what you want to do with your Mustang. If you are going to run around town and drive her back and forth to work I would say No... If you are going to throw on some axle back exhaust and the intake I would say No... If you are creating a show car I would say yes. The Boss Manifold is amazing Eye Candy and makes the entire under hood appearance that much more spectacular, we are expecting to bring home a few more trophies this year with addition of the Boss 302 intake. If you are going to track or Drag the car I would say yes, only if you are willing to pay for the additional parts to pick up for the loose of torque. Since I have installed the Intake I have jumped to 4:10 gears from the sluggish 3:55. 4:10s is definitively a better combination with the Boss intake or at least have the 3:73's. My next step to pick up for the loss of torque is a High quality set of Long tube headers and high flow race cats. This will give the car more ft of TQ then it had with the original stock intake, and you will also keep the top end power as well gained from the Boss, this will give you the best of both worlds with simple bolt ons. If you were going to drag race the stocker vs. the Boss 302 intake (with same headers and gears) you would have amazing 60 ft times then ultimately get passed by a Boss 302 intake because the Stock intake falls on its face 6000 rpm and is passed by the Boss at 5500 rpm for both Torque and HP (don’t argue that the Boss won’t catch the stocker with all that torque the stocker is likely to spin its wheels). If you were going to track the car with the Stocker vs. the Boss 302 intake the stocker would simply not be able to keep up the high RPM tq and hp that is needed for that style of racing. The answer is simple the Boss 302 intake is incredible eye candy, and if you are willing to go the extra mile by installing the other bolt ons that is needed to make up for the loose of torque by all means go for it (isn’t that why we do this anyway), And we haven’t even touched on the benefits that the Boss 302 Intake will give us with cams; heads or even boost. Just look at the numbers AM is putting down with the Boss 302 intake on their project car. I cannot wait to get back to the track this season.

    Interesting install

    Well, after 3 manifold bolts broken I finally got the part installed. Which I broke bolts because I was using 89 in-lb's for torque and I believe I had a bad torque wrench. So I ended up just going without it. Also you will need an extra hose and clamps to run the hose up under the throtter body to the Green tube. I'm not sure how I like it so far, looks sweet; but we will see if I see or feel a lot of gains in HP.

    Difference in sound and performance

    First of if your doing this mod do it right and buy the installation kit. Ive seen some people rig their stock lines. Your spending the $$ do it the way it was meant to be done. As soon as the tune was done and I started the car I could hear a difference. I had the c&l intake already and this added a little more volume to the exhaust and engine compartment. At idle you can hear the coyote breathin deep. its a very unique sound. Performance - very very little notice in loss of bottom end power. but lets be honest if your doing this mod for more power those rpms arnt staying low for very long. and the car will hook better. when you hit 4k rpm hold on. where you ready to shift the car keeps gaining power. Overall im very happy with this purchase and would buy it again. My only issue was removing the stock fuel line So just becareful doing that.

    Excellent gains

    Right, so I got this the other day and bolted it on. I'm a complete novice at working on cars but I managed to install this, a C&L cold-air intake, and the 85mm throttle body. It's basically like a $40k lego set right? Install was not especially difficult although I was a bit worried about the bypass valve delete. There's a part that connects to the original manifold and the instructions from Ford on this (obtained on this website) say that it doesn't do anything and to just cap it off. Well...I did, but that still seems fishy to me. I've driven it plenty since, and it's not throwing a check engine light or anything like that so I guess no harm no foul. The only other part of the actual install that was a bit hairy was disconnected the fuel rails. Obviously the fuel system is pressurized....I don't know if it was because I didn't have the fuel disconnect tool (I just used my fingernails to release the plastic clamp) but I got sprayed with gasoline and it went all over the engine when I disconnected the fuel rails. I cleaned it up and let the engine bay sit and dry for a couple hours after that just to make sure I didn't blow myself up. Install would have been much faster if I didn't do that....but I suppose I might also have lit myself on fire. Note to other inexperienced installers: rubber soled shoes, eye protection, and let the engine block cool off before you install this part! I also installed a new computer tune sent free from Bama. The process is fairly simple as I returned the computer to stock, then took my tuner inside and installed the software on my computer and then plugged it in and replaced the tunes. I didn't use the update tool on the software because it didn't ask me to do so: I have not run into any problems and I know the correct tune is installed because my fuel cutoff is much higher than before. It's still a bit disconcerting but that's just because I'm a novice. Actual performance gains: Wow. It's obvious right away. Before the car revved nicely and power peaked around 5500rpm and then fell off at 6500rpm. Now there's a VERY sharp increase in power right at around 5000rpm (feels very similar to a turbo spooling up) and the engine just pulls at that same level all the way past 7000rpm. My butt-dyno says at least 60hp from the tune, throttle body, cold air, and intake manifold. My x-pipe roush exhaust probably isn't hurting anything either.

    If looks could kill...

    This was the coolest bolt on I've ever bought from AM. It went on very easy, with no issues. I did not buy the purge valve installation kit. I followed the install from a mustang forum where the guy did a awesome walk-thru on the installation. You end up bolting the old purge valve to the block and you don't even have to add wire to the harness. I was not prepared to see a bunch of unpainted aluminum and beige paint splats from the engine manufacturing process under the old intake. I bought some flat black engine paint and blacked it up under there before the new intake went on...Trust me on this, it looked awful. I broke out the shop vac and sucked up some sand from there before painting. I also installed the JLT carbon fiber CAI at the same time, the CAI came bundled with the Bama tuner and the whole installation was pretty quick... Just a few hours including my OCD cleaning and painting. I love the look of this intake. I am happy with the gains and overall look of the new parts. Be sure to buy the Boss 302 strut tower brace, it just adds the killer final touch.

    Boss 302 Manifold WOW!!

    I received my manifold and strut tower bar within 2 days of my purchase. It took me a little over an hour from start to finish. I would recommend that you have a few rags to cover the fuel line crossover tube since it makes quite a mess when you disconnect it and each injector. I didn't order the complete kit, so I used 3/8 fuel line to reconnect the purge valve to the manifold and haven't had any issues. They say you lose some torque on the low end, but I honestly couldn't feel it. My butt dyno says I make much more power than before and I don't regret my purchase one bit. Thanks AM and Bama for all your help and service.

    This was an excellent upgrade. I already had an AirRaid intake and a tuner device which I purchased from A.M. I bought my Ford Racing Boss 302 intake manifold for under $500 (on special). Installation was easy and straight forward. Another A.M. customer has submitted detailed installation instructions with color photos that were most heplful. American Muscle followed up and delivered the upgraded downloadable BAMA tunes before I even received the manifold. This part looks BadAss under the hood and will dramatically increase the power band at higher RPMs. I Love it!
