      Review & Installation Video

      Hey guys, Stephanie with here with the SR Performance 70-millimeter throttle body for 2005 to 2010 V6 Mustangs. The SR Performance 70-millimeter throttle body is going to be for the Mustang owners out there that already have some supporting mods and want to make sure 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, as long as you've got some supporting mods, 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 air flow to fully benefit from the largest throttle body, especially since we're talking about a V6 here. If this is the case with your car 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'll need so you can utilize a bigger throttle body for more air flow and improved throttle response.The V6 came from the factory with a 65-millimeter throttle body, so bumping up to this 70 is opening up some air flow without a doubt. Just compare the 70 to your stock throttle body and you'll notice a difference. If you've got a car with some big mods or possibly even forced induction, then you'll know that you would be fully utilizing the greater amount of air flow that this throttle body has to offer.Just like your basic bolt on modification, this throttle body does not 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 is going to be a lot like a cold air intake in this sense. It helps the car for sure, but you're not really going to notice a whole ton of horsepower as you're driving along. It's not a mod that you're going to notice a ton of difference with.Looking at this a little bit more, it is a CNC machined 356-grade aluminum body. This is to ensure an OEM quality and a perfect fit. This throttle body also has some other great qualities as well. It has beefed up components like OEM die stamped throttle linkages, double sealed bearings, and O-ring throttle shafts which are features that make it highly compatible with a drive by wire setup.As far as price, you can expect to spend in the range of $250 to $300 for this 70-millimeter throttle body. This is less expensive than the BBK option on the site by about $60. Throttle bodies do tend to be pretty expensive but keep in mind that this is complete and ready to go. You won't need to purchase any adapters or anything else to make this work for you.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 socket sizes, a ratchet, a 5 millimeter Allen wrench, and of course a volt meter. SR Performance suggests to reuse the stock throttle body gasket, 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 disconnecting the negative battery cable and unplugging the throttle body electric motor, the TPS, and the mass air meter. You're going to want to loosen the hose clamps on the throttle body and the airbox so you can remove the inlet tube and get to the throttle body. There are only four bolts for the throttle body, so back those out and then you can remove the throttle body. You will need to transfer over some things from the old throttle body over to the new one, but the instructions will walk you through all of that. Once you have the new throttle body ready to go, it's just a matter of reinstalling with the four bolts and reassembling the items that you moved out of the way.Wrapping things up here, the SR Performance 70-millimeter 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. It has upgraded components. It's easy to install and it's 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 more online, and for all things Mustang, keep it right here at

        Stay away from SR

        SR Performance doesn't offer a warranty for there parts, throttle body has vacuum leak from TPS seal. And from the other reviews I'm seeing the same problems I had so it seems to be an on going problem. It's to bad AM continues to sell a product like this. Will stay away from anything from SR.

        SR Performance 70mm Throttle Body Install

        Easy install took about an hour even though I had to take it apart twice because I forgot to tighten the allen screw for the adjustment pin! Was hoping for a different sound than what I had with the OEM 65mm body and the throttle body spacer but I cant really tell any difference. I have ordered new tunes, we'll see if that makes a difference.

        Tedious work to get the right voltage but still a cheaper throttle body ain’t complaining for the performance gain.

        1 2006 V6 - Traft Installation Time: Less than 1 Hour

        Nothing but trouble

        Bought this despite reading some people having issues, figured if I followed the instructions everything would be alright. So I followed it ensuring the voltage was in the range that it should be, everything seemed alright at the start. Then while driving on the freeway I no longer could accelerate, had to pull over and turn off the car and turn it back on and drive very cautiously home. Turns out I was getting error codes P2110,1,2 codes. I made sure the voltage was adjusted to match the OEM TB so not knowing what else I could do I reinstalled the old motor parts onto the OEM TB and reinstalled it and haven't had any issues. I contacted AM about returning it but since I don't have an mechanic report stating it's defective and since it was previously installed they refuse to return it. Yet AM themselves state this is a basic bolt-on mod, simple installation for anyone. So having a mechanic report for something that isn't required to be installed by them seems a little stupid.

        2 2007 V6 - EthanA Installation Time: Afternoon


        There is a noticeable performance gain, especially when paired with a CAI and a nice tune. Definitely better throttle response, and a couple more horses under the hood. However, I have had several issues with this TB. For one, it makes a very loud whistling noise when accelerating, it almost sounds like a vacuum leak. I don't mind the noise, but not knowing where it's coming from is frustrating. My biggest issue by FAR is that it occasionally sets my car into limp mode. It throws codes like P111 and another one (I forgot) saying that something is wrong with the TB, but then they go away. However, in limp mode, my car forces idle RPMs, and refuses to accelerate even when pressing on the gas pedal. I have no check engine or wrench light illuminated. I installed it myself and it went fine, it just put my car in limp mode the other day and I knew it was because of the new TB. I am having my TPS looked at because I did not adjust the voltage from the stock to the new one because I heard it wasn't necessary.

        Extremely noticeable difference!!

        The installation was really simple, and only took me 55minutes, considering I was making Instagram videos. Once I turned on my mustang after installation I heard a deeper grumble to my v6, not to mention response when hitting the gas is a lot more instant, it wakes up the v6 if you ask me!!! Add this with an air intake and your motor will come alive!

        Good TB, But There's a Catch

        The instructions are simple enough, the build quality is solid, but I had an issue. The larger TB will not connect to my factory CAI hose. My only complaint is that American Muscle did not provide this information. I bought this part because I wanted to fix an issue and get a little more power at the same time. So now, in addition to the $250 for the TB, I have to buy a compatible CAI. So in conclusion, the TB is high quality and a good bolt on, but American Muscle dropped the ball by not providing all the necessary information.

        5 2005 V6 - AustinC Installation Time: Less than 1 Hour


        Came off fairly easily and the new one went on very easily. The only thing is the whistle. Some reviews say it's nice and some say it's terrible. For me it's pretty terrible. People say it's from sharp edges in side but i haven't had time to figure it out yet. But other than that its mixed with the pypes dual exaust and then the simple speed demon, nkg spark plugs, 8mm wires, and a custom bama tune. With that it was pretty noticeable. The power in the low rpms felt a bit stronger and the acceleration itself sounds and feels smoother.

      I'm suspicious that my car is running lean already with a K N Cold Air intake and no tunes. Would this make it way too lean, or would the computer be able to account for the difference in air?

      • If you are currently running lean with the K&N Cold Air Intake, I would highly suggest getting a new tune written for your vehicle. Adding this throttle body will absolutely make the vehicle run more lean which will most likely throw check engine codes.

      Hey will this work with JLT next generation cai?

      • Hi, This throttle body is compatible with the JLT next generation CAI for the 05-09 V6 Mustang.

      will this throttle body fit the air raid throttle body spacer

      • It will fit but the spacer will restrict your air flow, because this throttle body has a bigger bore than the spacer. You will get better performance with just the throttle body.

      just got this in the mail, grtting ready to install..what is the U tube used for??

      • The "U" Tube is used to connect two vacuum lines together since this Throttle Body does not have the ports for them.

      Helpful (2)

      Where are the vacuum lines located for the U tube? I have an annoying vacuum leak sound after installing this.

      • The vacuum line should be close to the throttle body unless you completely removed them. Not all applications will need to use the supplied tube for install.
