    Hey guys, Stephanie with, here with the BBK 85mm Throttle Body for 2011-2014 GT's and 2012-2013 Boss Mustangs. The BBK 85mm Throttle Body is going to be for the Mustang owners out there that already have some supporting mods and want to make sure that they're allowing as much air as possible to get to the motor. A throttle body isn't a mod that's going to add a ton of horsepower by itself; it usually works best when you've already started modding and need to make sure that the throttle body isn't acting as a bottleneck anymore. What you're really going to notice with a throttle body is more along the lines of throttle response, and not so much horsepower and torque gains. Most people tend to think that bigger is better when it comes to modding and that isn't always the case, especially when it comes to an item like a throttle body. Bigger does cost more, but the fact is that mildly modified or stock Mustangs do not have enough airflow to fully benefit from the larger throttle body, and if this is the case, then installing the biggest throttle body is only going to hurt performance and reduce throttle response. The current mods and the goals that you have planned for your car are going to determine which throttle body you will need, so you can utilize a bigger throttle body for more airflow and improve throttle response. The GT and Boss came from the factory with an 80mm throttle body, so bumping up to this 85 is opening up some airflow without a doubt. Just compare the 85 to your stock throttle body and you'll notice a difference. But if you've got a car with some big mods or a forced-induction car, BBK does have a 90mm option. Just keep in mind that bigger isn't always better, and that you want to make sure that you actually need the 90mm so you won't be hurting performance. You also have to keep in mind that there is a pretty big price difference between the two options. So, just like your basic bolt-on modification, neither of these throttle bodies require a tune to run or work on the car, but I will say that a tune will definitely help to get the most results out of the throttle body. The throttle body's going to be a lot like a cold-air intake in the sense that it helps the car for sure, but you're not really going to notice any more horsepower as you're driving along. What you will notice, however, is going to be improved throttle response. Looking at these guys a little bit more, this is a CNC-machined, 356-grade, aluminum body. Now, BBK promises an OEM quality and a perfect fit, and right now I can tell you that it does look like OEM quality, and we're going to install this here in a minute so we can talk about the fit then. The throttle body also has some other great quality and some beefed up components. I'm talking about things like OEM die-stamped throttle linkages and double-sealed bearings, and these are things you like to see on an aftermarket throttle body. I mentioned the 90mm option from BBK earlier, and this is the largest available option for the stock intake manifold at this time. Ford Racing does also offer a 90mm option as well, but it's a little bit more expensive and you do have to purchase an aftermarket adapter plate in order to run it, whereas both BBK options are a straight bolt-on. This means that they already include all the necessary drive-by wire electronics, so it's going to be ready to go right out of the box. I'm going to keep with what I said and still say that this is a basic bolt-on. It's going to be a one out of three wrenches on the scale and should take about an hour to complete. You will need a few different socket sizes, a ratchet, and a 5mm Allen wrench. BBK suggests you reuse the stock throttle body gasket so that's what we're going to do with our car here today, but you can always pick up a new gasket easily if you don't want to reuse yours. There are a few things that you'll have to get out of the way before you start the install, like removing the strut tire brace if you have one, and the engine cover, and also disconnect the negative battery cable while you're at it. You can leave the sound tube on the inlet tube and leave it connected, but disconnect the smaller breather tube from the air inlet tube. The air inlet tube will need to come off and be set aside so you can get to the throttle body. There are only four bolts for the throttle body, so back those out, and as you remove the throttle body, flip it to unplug the throttle position sensor on the bottom. If you're reusing the stock throttle body gasket, remove any oil or debris and then ready the new BBK Throttle Body by first clipping in the TPS under the bottom. Use the supplied bolts to bolt the new throttle body up, reinstall the air inlet tube, and connect the breather tube. Tighten down all of the clamps, reinstall the engine cover and strut tire brace and after that, all that's left is reconnecting the negative battery cable. Wrapping things up here, the BBK 85mm Throttle Body is made from a high-quality aluminum casting. It will allow for more air flow and it's a direct bolt-on install that doesn't require any tuning. All of the electronics are pre-installed and the throttle body is ready to bolt on from the box; you don't need to purchase anything extra to make it work. You can check this throttle body out, along with the 90mm throttle body, online and for all things Mustang, keep it right here at

    Excellent Performance Gains. Replace your restrictive factory throttle body with a BBK Power Plus Series Throttle body that features a generous, free flowing 85mm bore design. It is a simple, direct bolt-on install that does not require any computer tuning to enjoy the newly discovered power you have put on your drive-by-wire pony. Expect to see gains of up to 10-15HP and 20-25 TQ.

    Quality Construction. This BBK Mustang throttle body is CNC machined from high quality 356 aluminum to ensure OEM quality and a perfect fit. Features like OEM die stamped throttle linkages, double sealed bearings, and o ringed throttle shafts make this throttle body one of best on the market today.

    Bolt-On Installation. The BBK Throttle Body is designed for a straightforward installation and features pre-installed electronics making it a no-hassle go fast upgrade with no tune required.

    85mm or 90mm ?? I plan to throw on these mods on my 2012 GT in this order: 1. Bama Tuner, 2. Airaid CAI, 3. BOSS Intake Manifold. Then for the last bolt on mod i would like either a BBK 85mm throttle body or the 90mm. Which one would be the best purchase in this particular case? I don't want to over-do it with a 90mm if that is too large for these mods.


    • I did the exact same thing to my 2012 GT in that order. You are right the 90mm is a little over kill from all the research I did unless you plan on a supercharger later. You are going to love it when you get done!

    Do i need to inform bama if I add Throttle body My car is customed tuned with sct tuner, from American Muscle. If I add throttle body, do I need to retune? Thanks


    • You don't need a tune with this throttle body; however, a custom tune will definitely help you get the most power out of the upgrade. If you already have the Free Tunes for Life since you purchased the tuner from us, I highly recommend that you give us a call so we can update your tune!

    Will the BBK 85mm throttle body work in conjuction with an Airraid CAI? I've recently upgraded the stock air box wth an Airraid CAI kit. Will the inlet tube fit this particular throttle body?


    • Definitely! We've had other customers purchase both together as well and they love the combo. Enjoy!

    • The BBK 85mm Throttle Body will fit with most aftermarket intakes, however, without know the size of the coupler included with your cold air intake, we would not be able to confirm its fitment.

    On a 2014 with ported heads, a roush cai, and axlebacks, would it be better to fit the car with an 85 or a 90mm TB? I do plan on getting long tubes and a stage 1 cam done eventually.


    Will this TB fit a jlt cold air intake? Millimeter wise?


    • Yes, this BBK 85mm Throttle Body will certainly fit with the JLT cold air intakes we have to offer.

      Excellent horsepower boost. At least 35% more air intake.

      I already have the BBK cold air intake installed, and once I installed this BBK throttle body, I noticed a gain in acceleration right away. I also noticed the sound of the air swooshing in everytime I accelerate. On another note I even noticed a higher, louder sound at idle which i love because it gives the car more of a muscle sound. Overall I must say I was impressed with all of the results of adding this throttle body in with my cold air intake. When these two parts are working together they really shine. I did not expect that much of a difference in speed and even the sound at idle. I would recommend this item if you're looking for a fairly inexpensive way to beef up your mustang without messing with the stock factory tune and getting into complications. The throttle body was fairly easy to install and I have no experience with working under a hood.

      Excellent product - produces driveablity improvements and slight HP increase

      I am one of the folks who got a nice acceleration and high rpm free spinning type of improvement with this BBK 85mm. Car is a little louder especially in from the air box. Idle is smoother and about 25RPM higher and very stable. No more stalling at traffic lights with this TB. I felt it pulled harder and was more easily able to blow past the factory redline. Since putting in this TB I have found out that the Coyote engine with factory intake likes to be shifted about 7000, no more.. at 7100 it seems to taper off. Before this TB I never had the accidental problem of exceeding 7000, it just wasn't easy enough to do. Some say TB upgrade is not worth it for a stock based engine, my experience shows the opposite. Dyno tests coming ASAP.

      Definite improvement in throttle response. I would not make this my first modification though.

      It took about one hour to install and there were no installation issues. The instructions were good and the install is very easy. The throttle body improves the throttle response, particularly from about the 2300-4500 RPM range and seems to provide slightly better mileage in around town/city driving - though I have no emperical data to back up that claim. I also have a low restiction cold air intake (CAI) on the car as well and they seem to work well in tandem. The price is on the high side in terms of horespower bang-for-the-buck compared to some other modifications you could choose. I would not make this my first modification if you are mostly looking for HP increases or if your money to spend is limited. Overall, I am pleased with the product so far. This is my third modification to my 2011 GT, the other two being a Rousch low restriction Cold Air Intake (CAI), and the Ford SVT GT 500 axle back muffler kit.

      This product is over priced alot. it is worth buying though. it does give you any power that i can tell but increases throttle response. throttle response is definately alot better but again, if there is any power gains i cant tell.

      If you have mods add this.

      I have a C&L intake without a tune, a Pypes X pipe, and Flowmaster American Thunder Axle Back exhaust. I am waiting to run the warranty on the car before load a tune so I was looking for another bolt on that would not require a tune. A throttle body upgrade seemed like the next logical step, however I was a little skeptical based on some of the reviews and didn’t want to waste money that could be spent on suspension upgrades. The install was simple and straight forward and took less than an hour, even doing it in the dark with only a flashlight to guide me. The end results really surprised me. There was a noticeable increase in throttle response and power on takeoff. In the higher RPM’S the power is level and there is a strong pull from the engine where in the past I felt as though there was a slight drop off after 5000 rpm. There is no difference in idle however I can now smoke the rear tires in first and can truly say that I need to work on my suspension to get the rear wheels to lock up. On a recent long trip I set the cruise at 70 MPH and was getting close to 27 mpg with 3:73 gears. All in all a great purchase and well worth the money when used in combination with other mods.

      BBK 85mm Throttle Body

      I bought the BBK throttle body for performance & it did pick up some throttle response & low end torque, what I was most surprised about was an increase in fuel mileage. I have a 2012 Track-pack 5.0 with 3.73 gears & I was averaging 24 mpg on trips. Last week after I installed my throttle body I drove to the Charlotte Auto Fair & got 26.8 mpg going & 27.2 on the way back. I am extremely pleased with my BBK throttle body!

      Ordered this along with an Airaid CAI and SCT tuner. Took my time but still installed within a very short period of time. Excellent fit and finish. This is the first BBK product I've purchased, but I'm sold on the company's quality. I was surprised it was only 5mm larger in diameter than factory, but it does make a difference.

      BBK 85mm TB on N/A application

      Had this installed after my Longtubes were installed. We did a couple Dyno pulls and only gained maybe 2HP and 1 ft lb of torque...Increases in throttle response are barely noticeable...It may "sound" better when you're on throttle, but this thing isn't worth half of what they charge for it.... Maybe on a supercharged application there may be some performance gains, but not a car full of bolt-ons. I pretty much got just as much power out of the stock TB...

      Good starting point for new stangs

      This mod was simple enough to install; took less than an hour and I could feel the difference immediately. My stang was quicker off the line and had a faint whine when the air started flowing. Extra power tapered off quickly and a bit pricy, but still a good mod if you don't want to flash tune.

      I noticed a decent amount of low end torque. However, it feels like my top end has decreased. Also my mileage has dropped by 3 mpg. Not really worth it for the lack of real gains. I'm going to get it tuned to see if that helps.

      BBK Throttle Body 2013 GT

      After a combined upgrade of a JLT CAI, Boss 302 Intake and BAMA tune the 85 mm throttle body produced a noticeable throttle response at low end and a notable increase in torque though out torque band up to 7500 RPMs. After adding the throttle body I requested a tune from BAMA to incorporate the potential of the new throttle body which brought on the WOW factor. It looks great and functions perfectly. The price is a tad bit high.

      Easy bolt on

      I ordered the BBK 85 MM Throttle Body and it arrived on time. The mounting bolts that came with it were too short. I called BBK and they sent me the correct ones that came 6 days later. A M should have made sure everything was right with the part before they shipped it out. At any rate, installation only took about 40 minutes. I already had the Roush CAI and Axle Back Exhaust and a Bama Performance Tune. The 85 MM throttle body improved throttle response and there is a noticeable power gain at higher RPMs. An added bonus is 2 mpg better mileage at cruising speed! I am happy with the part and I recommend it.
