- How to Install BBK 90mm Throttle Body on your Mustang
Hey guys, Stephanie with AmericanMuscle.com, 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 AmericanMuscle.com.

The addition of this throttle body to the rest of my upgrades has resulted in an astonishing increase in throttle response and overall power. Installed in less than 10 minutes HIGHLY recommend!Helpful (0)

Worth it? 90mm throttle body
You hear on the internet a tons of mixed reviews, but that’s because people don’t really know when to buy this part and just slap it on at the wrong time. To maximize gains out of a part like this one you have to understand how this part work not just what it does. You’re NOT going to see substantial gains combining with just a CAI and Axel Back exhaust. But if you combine this throttle body say with a set of “larger injectors,” E85 Tune, and a set of headers or mid-pipe of sort, then you will see the gains advertised. So overall since I’m deeper into my build. Great product! Tons of added torque, and takes less than an hour to install.Helpful (5)

BBK 90mm Throttle Body
Big improvement over the stock 80mm throttle body. Have great high end horse power gains, with little to no change to my low end torque as well. Last but not least looks great on the car.Helpful (12)

What BBK Throttle Body works best with my 2012 mustang Gt 2012 Mustang GT auto transmission, 3:55 gears, Airaid CAI, Bama costum tune, BBK long tube headers, BBK Caded Shorty X-pipe, Borla Stinger S-Type Mufflers.
I would say 85mm but if your planing on getting The Boss 302 intake then get the 90mm, I have a similar set up as you and I have 435rwhp but I have the 90mm w/ boss 302 intake
I have a 2011gt with c&l cold air,bama tune, and boss intake. Would I get better performance from the 85 mm or 90 mm throttle body?
I have a 2012 GT with the same modifications (Just an Air Raid CAI). If it were me and I was going to make that investment, I would go with the 90mm if only because the stock throttle body is 80mm. It doesn't seem worth it to put $400+ for the 85mm. I also believe the 90mm will help down the road if you decided to do heads or valves. Plus at the end of the day, more air can't hurt.
Would there be an improvement by adding the sr spacer with the bbk 90mm throttle body?
The SR spacer would not be compatible with aftermarket throttle bodies.
I’m curious to know will I gain a noticeable amount of hp with my current set up. JLT CAI, Boss 302 mani, BBK long tube headers, BBK O/R x-pipe, corsa axle back running a 93 octane race tune. I have a ‘14 GT Thank you in advance
I have a 2011 v6 that is procharged and I would like a larger throttle body than the 73mm offered for my model. Would this 90mm or the 85 mm be able to fit on my application?
Yes the included spacer would still be required.
You will measure the inner diameter to find out the true size of the throttle body. The advertised size is the bore size of the inside of the throttle body right at the entrance.
The intake should fit without issue, but you may have to stretch the coupler that attaches to the throttle body for the best fit.
You technically can put this on an otherwise stock application, but you'd probably end up losing power. I would suggest to speak with your tuner upon when they would suggest this throttle body relative to your tunes. If you do not have an application that has significant enough modifications that do not require custom tunes, then you would not have significant enough modifications to warrant the installation of this throttle body.
Both throttle bodies will essentially be the same quality. However, since the ford performance throttle body will require a tune, the performance will be better overall when compared to the BBK which does not require a tune.
90mm bore throttle bodies work great on heavily modified or force inducted GT Mustangs. Stock or mildly modified GT's do not flow air enough to benefit from this larger Throttle Body. Some customers still want to upgrade to this throttle body though. Alone, the BBK throttle body does not require a tune but one is recommended to see the gains from it. Heavily modified Mustangs usually have custom tunes on them and either throttle body can be included in a custom tune.
The BBK 90mm Throttle Body will work with your 2013 Mustang GT equipped with a K&N Blackhawk Cold Air Intake.
We have not tested the BBK 90mm Throttle Body on the 2018 Manifold, but believe this would fit.
Yes, this throttle body will work with the C&L Street Cold Air Intake w/ 95mm MAF.
This will require the use of the included spacer for use on the stock manifold only.
