Review & Installation Video

Review & Install Video

Hey guys, Mike Wilson here from Bama custom tuning and AmericanMuscle.com, 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. http://www.americanmuscle.com/free-sct-custom-tune.html http://www.americanmuscle.com/sct-custom-tune.html

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 (www.americanmuscle.com/bbk-85mm-throttlebody-112gt.html). 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.

    Still unsure

    Depends on what you want. I already had a CAI, 1 7/8" headers, x-pipe, over axle, Borla stingers, and 3.31 gears and it completely changed the way the car sounds at idle and normal driving conditions. The car is so much quieter. Only at WOT and accelerating does the car have the muscle car growl it used to with the stock intake. Driving is very smooth when you're climbing through the gears, and you can definitely feel it up top as well. Punching it in 2nd gear will definitely send you back into your seat at 3500 rpm. Worth it? maybe if you spend a lot of time above 5500 rpm...but if you love the muscle car growl while normal driving then don't buy this intake.

    It looks "killer" under the hood! A lot more aggressive than the stock manifold. Not embarrassed now when I raise the hood to view the power plant of my GT. Still working on the tune tweaks, but all-in-all nice performance gains.

    Manifold adds Class and Performance.

    Very happy with this new manifold. Read the install reviews posted on this site, and saw that the guy with a broken hand did it in like 30 minutes and I thought, this should be a breeze. Was not a breeze, it was very frustrating if you're not already a mechanic. I had a race shop ready to do it for $100, and there were times during the install I wished I had taken the beast to them. Took me three days working a few hours a day. I had to get a new torque wrench, mine did not go below 10 foot pounds. Of course I was tracking the 89 "inch" pounds, which translates to just 7.42 foot pounds for the manifold and fuel rails. I purchased the install kit, new Boss strut brace, and blue coil covers with this manifold. Had some difficulty getting the chrome BBK CAI to fit back into its location but eventually was successful (picture of end result posted to this site). My friends at Bama provided a new 93 octane Race and Ghost tune. The car already had BBK 90mm throttle body, BBK 1 7/8 inch LTH, BBK CAT delete X Pipe, LTH Over Axel Pipes, Borla ATAK mufflers. I can definitely tell the difference with the new Boss 302 manifold now on the engine. Seems to do an exceptional job at tying in all the other mods I mentioned into a seamless and smooth power band, much better than the stock manifold. Like some of the other reviews, I noticed the "Gods of War" unleashed once I got above 4000 RPM. The car is incredible, special thanks to American Muscle and Bama Performance for helping make my Mustang one of the baddest Naturally Aspirated mustangs out there!!!!

    Boss 302 intake manifold is well worth the money

    I bought this manifold with Pypes H pipe, CandL cold air intake, SCT tuner tuned by BAMA with race tune mixed with FlowMaster Hushpower exhaust. My car runs like a champ. Sounds like a panther on steroids. This intake manifold took my car from max rpm's around 6,800 all the way to 8,000 rpm's. Hands down, buy it! Top end is wicked fun. Spinning at 60 mph, and I hit mid 70's in second gear. I have the track pack with 3.73 gears and this is a fun setup. Had it dynoed and it got 472 to the rear wheels. Inexpensive mods for such massive gains. You can hear my car take some deep breaths whenever you mash the pedal with the Boss 302 intake. Top end is where it's and there is no low end lag. Worth the money for sure.

    Great Mod

    This is kind of a sleeper mod. If your just casually driving you don't really notice it being there but once you put your foot down and 4k on the tack hits you'll find out what it does. Great upper rpm gains just make sure on your tuner you set your rev limiter to 7500 rpm.

    Awesome intake well worth the effort

    I read a lot of reviews online where people said you'd lose low end torque. That is simply not the case. Perhaps if you have no other mods and bolt this on to a stock car you'd lose a little low end, but in my application I felt no loss. This intake is light, like you might accidentally throw it when lifting it out of the box it's so light. Being a guy who had Foxbody's forever and being used to heavy intakes, this was a pleasant surprise. The install is a breeze, requiring little technical knowledge and only minimal ability to install. I actually installed it with a fractured wrist by myself. I read all the available install guides, and settled on the guide supplied by Ford Racing as the simplest and easiest to follow. The only modification the Ford guide didn't show was to the Fuel Vapor valve. Just add some 3/8 fuel hose and link it to the Boss intake via the green plastic covered inlet and you're golden. Top end gains are very nice. Install time was about 1.5 hours (again with a fractured wrist) Required tools are minimal. The only tool that could be considered specialty would be the torque wrench which you'll need one that will go down to less than 10 ft pounds. Bama had my tune revision in less than 24 hours. Overall it was a great experience.

    Boss 302 and Bama tuner review

    I just purchased the Boss 302 Manifold and also a Bama tuner. I was doubtful as to what the real outcome would be by adding these mods. The change was unreal, with the track lock on, there was a very noticeable change in the throttle response and once it came up on the power band I was gone. I then took off the track lock and was in the sport steering mode and I unleashed the beast,, I could not hold the car down in the first three gears. I still have to install the BBK long tubes and the BBK catted Xpipe, after that,,, new tires will be a must in order to get the power to the ground, and get it to hook up. I also have a KandN CAI, throttle body spaces and Flowmaster pro series axlebacks. The install was simple and easy, and the change was dramatic. Thanks AM for the information you provided me and the discussions about the products. I will continue to use AM for all of my Stang mods, and know, not only will I get the right information but will also get great service.

    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!!
