    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!!!

    Cross00

    • 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!

    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?

    Dylan5590

    • 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.

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

    CRD

    • 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.

    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

    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.

    Dave

    • 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.

    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.

    Charlemagne

    • 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.

      Great high-RPM Gains

      This install was pretty easy and straightforward. By putting a washer or two on each strut tower bolt, I was able to still use my SR Performance strut tower brace. When I lost one of the green rubber gaskets under my #4 cylinder fuel injector, finished the install and fired it up, I had a ton of engine codes and a rough idle and stalling problems until I figured out what I had done and fixed it. Now that its working right, here's what I have: A LOT of torque lost on the bottom end. Bigtime! It feels like how my GT felt before the Bama tune. It really makes me sad. On the flip side, once the RPMs get over 4,000, my GT goes beserk and pulls super hard all the way to redline at 7700. Now the problem is just finding someplace to get the RPMs that high, haha! I'm thinking as a daily driver, this mod will pair really well with a gear swap...but for right now, my car just feels sluggish and sad until 4K RPM.

      Good bang for the buck.

      Everyone told me it wont make a big difference, boy were they wrong. 85mm bbk, JTL cold air, 93 octane tune, and Boss 302 intake. Wow is all I can say. Boss 302 must have increased horsepower by at least 35-40. Looks real good also, sets off everything under the hood.

      What a big difference a intake manifold makes

      I was kind of skeptical about this product when i read different reviews, so i put alot of thought in it and im glad i made a great decision on purchasing the boss 302 intake manifold for my 2012 mustang gt, its very easy to install and it looks great under your hood ,and paired with my mods BBK 85mm throttle body, specrta CAI ,BBK oil separator, xpipe resonator delete and roush axle backs, all tide into bama 93 performance tune its performance is great

      Top end gains

      Really feel it on the top end when I’m at around 6500 RPM realistically only gained around 48 hp. The install kit is necessary IF you have the factory intake. But if not then the only problem is your purge valve. Just spend an extra $6 on a couple feet of emissions tube and reroute the original valve. Or get the install kit and route it underneath the throttle body. Easier than re wiring but only a temporary fix. Overall took about 2 1/2 hours start to finish. Would definitely recommend.

      Boss Intake

      Love this Boss Intake. I put it on my 2015 f150. It is bad to the bone!!! I got 33” tires, 4” lift, JLT cai, Ford performance catch oil can, 4.10 Ford Racing gears and omega tune. This thing pulls really hard from 3500 to 7350rpm. So happy with the Boss. Had to drill a hole in the back of the intake to put the map sensor.

      I should of done this sooner!

      I wish i would of taken the opportunity to do this when I purchased my Mustang. I love that I can drive around and it drives how it would stock but when you get it into the higher RPMs it wakes up and goes. If your thinking about purchasing it just stop and do it. I promise you wont be disappointed. It took about 2 hours to install but also did the JLT cold air intake with it.

      I can't say for sure whp gain on this mod alone but the boss302 mani combined with kooks 1 7/8" LTH and catted x pipe with Borla ATAK and bbk 85mm throttle body and custom dyno tune put my 2014 GT at 440 whp and 374 ft pounds of torque @6900 rpm. Sound is off the charts and I'm expecting to see some for sale signs soon on my neighbors front lawns haha. Installation is simple with some knowledge under the hood.

      Awesomeness!!!!

      This manifold was a blast to install! The only part that wasn't "fun" for me was soldering the new wire connections for the extended purge valve. I ended up just using electric lee tape to secure the connections because the solder just would not work with me. Other than that this manifold installation was very easy and fun. I installed an Airaid race CAI along with it and a tune through VMP. This car is a whole new beast!
