- How to Install a Boss 302 Intake on your 2011-2013 Mustang GT
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.

Better Than Anticipated
Just installed the 302 with JLT Series II CAI with REV X Bama tune: Amazing! After reading a good number of customer reviews and articles my expectations were moderate. While I don't know how many more HP and torque I picked up it is significant and really woke up my 2014 GT convertible manual shift with cat-back Roush exhaust. Even with a 2.73 rear this puppy will set you back in your seat. Both throttle response and power curve greatly improved at all rpms. The AM staff were great to work with too.Helpful (0)

More than I expected!
Didn't expect alot after reading about the pros/cons, but I'm really pleased to find a noticeable improvement in drive-ability and pull. Supportive mods might make the difference... in my case, JLT air, 85mm throttle body, sturdier lower control arms, and barton shift bracket, together with a 93 BAMA Boss tune.Helpful (1)

Worked as advertised
Really enjoy this product. I have an Airraid CAI installed and I wanted something to really tie it together a get some real HP gains. This really helped out! If you are looking into this make sure you also get the install kit!Helpful (1)

Had it ported for my 2014 GT and there are power and torque difference all through the RPM range. Haven’t hit the dyno yet but I can feel it. Installed it in 90 mins.Helpful (1)

Perfect mod for high rpms
This product is well worth it, heard about the cobra jet manifold but decided to go with this oneHelpful (1)
I've seen on another site that this is for manual transmissions. Will this go with my automatic transmission?
The Ford Performance BOSS 302 Intake Manifold is designed for manual transmission Mustangs only. The Boss inlet tube does not have provisions for aspirator tube hook up common to automatic equipped 2011-2014 Mustang GT's.
In the video it shows a baseline of 391 hp and 366 tq and after the bolt on and program it shows 404 hp and 351 tq. Where is the 61 hp and 43 tq gain???? It looks like 13 hp gain and 15 tq loss to me....... I am looking to pick up a 2012 Gt and would love to gain 61 hp from a bolt on, but don't see the gains here. Please let me know if I'm missing something...
I posted the same question before i saw this post, i was never really very good in Math but cmon. they show the video and your right its only 13 hp gain and loss on tg no thanks for $500
Will this product fit the stock GT throttle body? or is a bigger one required?
The Ford Performance BOSS 302 Intake Manifold (11-14 GT) will require a bigger throttle body than the stock GT throttle body. The BOSS 302 Intake Manifold is designed to channel more air directly into the engine. In this case, I would recommend upgrading your throttle body to either the BBK 85mm Throttle Body (11-14 GT) item #56145 (www.americanmuscle.com/bbk-85mm-throttlebody-112gt.html) or the Ford Performance 90mm Throttle Body (11-14 GT) item #50326 (www.americanmuscle.com/frpp-90mm-tbody-1112gt.html).
So I've done a little research and read that the boss manifold really shines in the higher RPM range and peaks somewhere between 7200-7500 RPM for shift points but noticed when I got my specific bama tune for this new part after installation that the rev limiter was still at 7000 so I'm kind of confused. Shouldn't it be higher?
I noticed the same thing when I got my tune. Called Bama and they explained 7000 RPM was like a baseline they use and I could go into that button on the tuner and adjust it higher when I load the tune on the car. The guy I spoke with at Bama recommended I raise it no higher than around 7500 RPM because this about where the peak horse power is found (if you're talking a stock Coyote engine with just bolt on's). The Boss 302 Mustang can rev as high as 7750 RPM but its internals are beefier to withstand the increased RPMs. So going much higher than 7500 RPM is a waste, and much higher than that, you begin to endanger some of the engine components.
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!
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.
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.
All the testing that I have seen the engines have made the most gains in high rpms but the seem to also gain a little at low rpm
All depends on how you drive it. If you drive 'normal' you will see some mileage gains. But, if you get all excited about the more power, sound and pure evilness of this, and drive it like I've driven mine... you're likely to get less mileage >:D
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.
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.
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
3.73's will be a better match with the boss intake manifold. Under noal cruising conditions you will not be in or near the power band of the manifold.
You have to call BAMA and order a new tune noting the use of the Boss 302 intake but just an FYI you don't need a tune to put the intake on and drive the car. the car runs fine without it. but gains will be minimal without the tune.
The stock GT tower brace will not fit. Only the stock Boss strut tower brace or aftermarket Tower braces made for the Boss will fit since the intake sits higher then the stock intake.

What's in the Box
Airaid Cold Air: requires the coupler, attaching the throttle body to the inlet tube, to be trimmed 1/4" off each side to allow proper clearance to the fan shroud
