  • Original Equipment on the BOSS 302 Mustang
  • Made from Light-Weight Composite Material
  • Black Finish
  • Short Runners for Optimum Flow at High Rpms
  • Fits 2011-2014 GT Mustangs with Coyote 5.0L Engine
Gain Up to 61 RWHP. Bolt on up to 61 RWHP and 43 ft-lb torque with the Ford Racing BOSS 302 Manifold. We Dyno tested this system in house on our stock 2011 GT with just a JLT cold air intake, so you can be confident you'll see real 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 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. When you want peak power, this Ford Racing BOSS 302 "runner in the box" Intake Manifold is designed to channel more air directly into your engine and set the stage for other power mods.

Premium Quality. Made of a high tech, lightweight composite, this manifold will help 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).

Legendary Ford Racing Performance. When you're adding parts to your pony, trust the folks who know it best to un-tap hidden potential and unleash the monster under your hood. This intake manifold is featured as original equipment on the BOSS 302 Mustang.

Strong Enough for Forced Induction. Tested up to 2 bars of pressure, this 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.

Stock Air Box. If you plan to run your new Ford Racing BOSS 302 Intake Manifold with your stock air box, you will need to purchase the BOSS 302 Mustang Intake Manifold Install Kit which includes all the additional parts necessary for proper installation.

BOSS 302 Strut Tower Brace. Reduce unwanted suspension flex while greatly improving the handling of your Coyote powered GT by adding the BOSS 302 Strut Tower Brace. The brace is the exact strut tower brace featured as standard equipment on the BOSS 302 Mustang. Please see drop down option above.

Application. The Ford Racing BOSS 302 Intake Manifold is designed to fit the 2011-2014 GT Mustangs equipped with the Coyote 5.0L 4-Valve Engine. Intake gaskets are included.

Technical Notes:

  • A new Computer Tune is required for installation.
  • Stock fuel rails can be reused for this application.
  • Stock and aftermarket strut tower braces designed to clear factory GT manifolds will not fit.
  • Some aftermarket Cold Air Intakes may require modification to the coupler or inlet tube for proper fitment. The JLT and C&L Cold Air Intakes will bolt-on with no additional modifications.

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.

How does this effect stock fuel mileage? While this manifold requires a tune, does it have to be tuned at 93 octane? And what does it do the fuel mileage? I have the stock manifold with an Airaid Intake and Bama Tuner.


  • Honestly, not a whole lot. I have this on my 2012 GT with Steeda CAI and the short runners do improve air flow and top end HP but overall the mileage is only negligibly effected for the better.

So will this fit automatics??


  • Yes this intake manifold is compatible with an automatic transmission equipped car. The automatic transmission requires a port on the cold air intake tube, so keep that in mind when ordering a cold air intake such as JLT or Air Raid. The stock boss intake tube was intended for manual transmission equipped cars so it may not have the correct port if you go that route.

Will this product work with throttle body spacers? I have an AFE Silver Bullet throttle body spacer in addition to my C+L CAI. Will this manifold work with both upgrades? Or will I have to remove the AFE throttle body spacer for this manifold to fit?


  • I have a JLT CAI and the throttle body spacer and just did the Boss intake install. Mine fits and clears the hood but rests on the fan shroud. I dont see any issues coming up with the way its mounted. Just takes a minute to adjust your hoses and clamps and you should be golden. Hope this helps.

    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!!!!

    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.

    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!!

    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.

    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.

    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!

    As advertised

    First off, AM and Bama staff are great. First intake I received was damaged in shipping. Contacted AM and they gave me an return number immediately, shipped a new one out and emailed me a return label the next day. I received my new tune from Bama within an hour of ordering it. As for the intake, I can defiantly feel the difference. Car is running better than ever and you can really feel the power over 4K with no noticeable low end lose. Took me about 2 hours, took my time. Performance mods: JLT CAI, O/R Xpipe, American Thunder Flowmasters, 93 race tune. Biggest problem is keeping the 285 Nitto's from spinning all the time : )

    Great Look and Quality

    Installed this intake on my 2014 GT Premium and could not be happier with the quality fit from Ford Racing and the look of the intake is great. The instructions were easy to follow and installation was fairly simple with the purchase of the install kit from AM and Ford Racing as well. The only issue I ran into was that the kit and directions are for a M/T and my Stang is an A/T. I had to do a little bit of extra plumbing of the vacuum lines for the master cylinder to clean up the install and relocate the check valve for the master cylinder vacuum line. Other than that love the intake and I do see the gains at higher rpm.
