Review & Install Video

Hey I’m Justin with, here with a quick breakdown of the SR Performance throttle spacer fitting all 2005-2010 V6 Mustangs. SR Performance is a company that has been earning the attention and respect of a lot of Mustang owners lately thanks to their high quality yet budget friendly performance and suspension components for a wide variety of Mustangs. If you would like to stay up to date with all the latest SR products released for your ride, just click on the banner to subscribe to our YouTube channel if you haven’t done so already. So the idea of spacers originated back in the carborator days when raising that carborator up a little bit would increase the plenum volume, and allow for more even fuel distribution. The idea of the throttle body spacer works off that same principal, by increasing the plenum volume it should equate to a couple more horsepower at the rear wheels. I’m not going to sit here and tell you this throttle body alone is going to gain you an extra 15 horsepower at the rear wheels because honestly it won’t, however, this mod is a great compliment to other bolt ons like your cold air intake kit, and your exhausts, but really shines when forced induction is introduced. Even way if you want to see what other 4L owners are saying about this product from SR Performance, I encourage you to click on the link below to head back to the product page at if you’re not there already, this way you can just read a couple of the reviews and see for yourself. The SR Performance throttle body spacer is designed specifically to work with your factory throttle body, and is made from 100% solid billet aluminum. It does of course come with all the hardware and gaskets needed for the installation, and best of all does not require a tune. Speaking of installation, this is definitely going to be one of the easier installs to tackle, you will need to remove the factory throttle body first, install your spacer to your intake manifold, and then go ahead and install your throttle body to the spacer itself. We do call this one about an hour here on the site but don’t be surprised if you get it done a little faster. Either way if you should have any questions or concerns about the product itself, or about the actual install, you can always give us a call or shoot us an email. So if you’re looking for an inexpensive, easy to install part that’s only going to help your performance as more mods are added, then you have to check out SR Performance’s throttle body spacer available right here at

Improve Engine Performance. Unleash your V6 Mustangs hidden power with a SR Performance Throttle Body Spacer. The SR Performance throttle body spacer increases plenum volume to improve the low to mid range torque from your Mustang's stock 4.0L engine, with noticeable gains seen between 800 to 2500 RPM.

Better Fuel Economy. The SR Performance Throttle Body Spacer not only improves the performance of your Mustang, but with its unique “Spiral Bore” design it also improves fuel efficiency. The Spiral Bore "spins" the incoming air for improved atomization of the air fuel mixture for better combustion.

Application. The SR Performance Throttle Body Spacer is specifically designed to fit the 2005-2010 4.0L V6 Mustangs with a factory throttle body installed. No tune required.

Combined with BBK cold air intake I ordered the BBK Blackout cold air intake which does not require a tune. If I combine this spacer with the intake will I then require a tune? Thanks,


  • Nope, this spacer alone, or in combination with a CAI that does not need a tune, will not require a tune.

Hi. I mounted the spacer with the 70mm BBK throttle body, and i read that it doesn´t work properly, if i dismount it will gain more hp? and another question, i have BBk cai and the sct tunner, what should I select the option to prime the fuel and air mixture? Thx AM


  • This is specifically designed to work with the stock throttle body, it is not designed to work with after market throttle bodies. For tuning questions I suggest contacting the American Muscle Tuning Expert customer service line and they can help walk you through or troubleshoot the process for you.

Will this work with the SR performance 70mm throttle body or if it won't can you suggest another?


  • Anytime doing a throttle body spacer you will need the factory throttle body for the proper installation. The spacers will not work on any aftermarket throttle body.

Is this TBS a big difference from the red air raid TBS?


  • The biggest difference in the throttle body spacers is the thickness of the Airaid spacer. Since both have similar vortex deisgns, both will gain you similar horsepower and torque numbers.


Helpful (0)

Will this TBS work if I upgrade my TB to either the SR or BBK 70mm throttle body?


  • The SR Performance Throttle Body Spacer is designed to work with the stock throttle body only. It may work in combination with other throttle bodies, however, due to the size increase of the throttle body valve, it may cause issues because of clearances with the spacer.

Will this TBS throw a check engine light?


  • Hi, This throttle body spacer should not set off a check engine light.

    Nice Bolt-on!

    I have just received this a few days ago. I added it on today. From start to finish it taken about 20 minutes to install. You just need VERY BASIC skills to install it. An 8-year-old can this job. MAKE SURE YOU DISCONNECT the battery before you start!!!!! I have bought a small tube of the silicon to make the fit a tight seal. It was about 3 bucks from auto part store. I have read the other comments about the bolts being too small. Well, I guess AM improved on that issue. The bolts that come with the spacer are long enough now. SPECIAL NOTE.... when you take the first set of bolts off, you are going to use a 5/16 wrench. The new bolts ends are a little bigger, it will use a 10mm, its easier to use on that fits on screwdriver's set... perfect fit! I notice a little difference in take off, and responses to opening the throtle. Since its rated for an extra 8HP and torque, I say its worth the extra $60 bucks. Keep adding these little bolt on, here and there, and your V6 coupe will be near the 300HP range.

    Would have given five stars but as usual Stack racing gives you the wrong screws.Spacer with new CAI has improved my MPG by 4. This is the second stack racing product I have purchased with the wrong screws. AM please do something. Get with this company and have them correct there errors. Don't these errors effect your business??

    Sounds great!

    Real easy installation less than an hour. I combo the spacer with a cold air intake. My first notice was its allowing the car to pull all the way to 90mph instead of choking and shifting at 80mph. If your thinking about putting a cold air on your v-6 this is a simple addition that wont put a hurting on your wallet.

    This product is the best bang for my buck yet! I ordered it online then a day later got it, thanks for very fast shipping AM. Overall it took me about 30 min to install. Very easy, normal hand tools will do the job. Didn't see a drastic change in HP but I might add it has a really nice start up now and rides really smooth. ALSO: there is a little whistle that you hear and it sounds somewhat like a turbo! its awesome! The noise will definately make those SS geeks think again..

    Throttle Body Spacer for my '07

    This was an easy install, took about 15 min start to finish. Good product, worth the money, does anything the 100 plus dollar TB spacer does. I'm skeptical that this adds any horsepower, (i did not buy it for the HP addition) however it will give you a mild MPG increase. PLEASE NOTE: THE BOLTS YOU REMOVE ARE 8mm AND THE ONES STACK RACING SUPPLIES ARE 10mm. i was not prepared for this and had to go searching for a 10mm. still only took 15min start to finish. a quarter inch drive ratchet and 3 or 6 inch extension helps a lot for the bottom left bolt. The whistle sounds pretty cool, not too loud. i recommend this product if you are looking for a cheap and affordable way to get a little something extra out of your stang.

    Incorrect bolts supplied. Works well though...

    The install takes about 10 minutes,but make sure your bolts are long enough first. I had to pick up 1/4" longer ones at the store. Don't slop too much silicone on, or it'll squish through the hole. Whistles a bit when you punch it. Seems to have a little more power, but not a whole lot. Pretty good mod for the price, even though I had to go through the hassle of getting new bolts. AM is refunding the difference.

    Good upgrade

    I installed this mod in myself in less than 20 minutes. You can feel a little change on the performance, it runs smooth and the acceleration is constant, quick and solid. The combination of this part with headers, Screaming Demon ignition, K&N air filter and the Flowmaster American Thunder increased my fuel economy to an average of 33 mpg and made my Mustang roar on the street. I have to remark that it makes a little whistle during the acceleration. I recommend this upgrade to every one.

    This has to be one of the coolest mods out there! I dont really notice a power gain but the sound and character it adds to your stang is amazing! It's really similar to the sound of a turbo spooling up once your car hits about 2000-3500 RPM. I have a Mac performance axle back exhaust which is pretty loud but can still hear that sweet "turbo" whistle even at full throttle...Best 40 bucks I ever invested in my ride (got it on sale)!!!

    If you are realistic, not a bad upgrade

    After reading all the different opinions on throttle body spacers, I decided to try this one out. I had no expectations of HP increase, so I was not disappointed. My primary goal was for better low end throttle response. After putting on a CAI, race tune and muffler the 4.0 run pretty strong, but lacks the punch on the line. There's a combination of factors but I noticed with the Flowmaster, the reduced back pressure really affected the throttle response. This spacer has helped. So people have reported better mileage, although I have not confirmed this. It seems to be worth the price, especially for such an easy install.

    Not that much gain

    I don't think you really gain 8 lb/lbs of torque. It whistles more, but it's not worth the cash. I had to splice in 3" of wire to fit in my car, but that's probably a ford fault

      Some people can but some people can't physically feel 8 HP even when it is present. You should definitely be feeling some improvement on your throttle response however after installing this spacer.

    Best Bang for Buck Upgrade

    This throttle body spacer may seem like an insignificant piece of metal, but it's quite the opposite. It makes the air spin as it enters the plenum which creates a wonderful turbo-reminiscent sound. Also, there is a noticeable difference in acceleration. And only for $40?!? Thanks AM!

    VERY easy to install. Take stock screws out, place the spacer behind TB, screw the new screws given with the spacer in ... congrats you are a mechanic. Performance gain inst too drastic, but the whistle alone when you accelerate is solid. I will be getting a Tuner soon to awaken my mods to full potential.

    No value

    I installed this product on my 2010 v6 and the performance actually degraded. I already have a BBK CAI and the SCT Tune which are terrific. Then I intalled the TBS and the car became sluggish. I don't recommend this product after my experience. And yes it was installed properly with no leaks. Ran the car for ~50 miles and took it off.

    I am a bit conflicted about this piece. I installed it at the same time as a CAI and a Bama tune, but after doing so I don't know if I like this. The "Cool whistle noise" sounds cool when you're revving the engine, yes, but when you're actually just hanging out at 2500 rpms it sounds more like a squeel from some bad brakes. Please keep this in mind :P The car pulls a lot better than before but I did do the other installs so I can't say for sure if it's just the spacer. MPG has gone up marginally though which is nice, even though I've been driving a lot more aggressively :P It was super easy to install, if you're looking for a first mod to get your feet wet then just get this. It's cheap, alters the car and is super easy. (You also get to play very close to the engine which is exciting!)

    No negatives, so it's gotta be good!

    Alright guys, so if you want peak performance and power for your V6, it's only obvious you should give your car more air volume and better atomization for better combustion. I have pypes shorty headers with x pipe and dual exhaust system, NGK plugs, GMS Coil, and now this throttle body. I've been using it for 2 weeks now since I installed it, took like 20 minutes. Easy to install and very straight forward. This mod alone really is not going to do much for you at all without assisting mods. In this case my ignition system is upgraded, and my exhaust flow is much less restricted then stock. These components flow perfect together. Again, if you plan or already have other mods such a CAI, tune, exhaust etc, then this will only enhance your performance. If you don't then this will be a waste of money to start as your first mod. The whistle it makes DOES indeed sound similar to that of a super charger just not as loud. Still very pleased with this inexpensive mod. I cant wait to get a CAI with a tune, should def. wake my beast up with my existing mods! Good luck guys!
