      Hey I’m Justin with, here with a quick breakdown of the SR Performance throttle spacer fitting all 2005-2010 Mustang GTs. 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. The SR Performance throttle body spacer is designed to work specifically with the twin 55mm throttle body on all 3 valve Mustangs, with the goal of increasing your plenum volume which in turn should give you a little bump in power and torque and even throttle response. The throttle body spacer itself is made from 100% solid billet aluminum, and while it won’t add a ton of power on its own, it is a great compliment to those other basic bolt ons, such as your headers, your exhaust, your cold air intake system, and even superchargers. If you do want to hear what other 3 valve owners are saying about this part from SR Performance, I do encourage you to click the link below to head back to the product page, if you’re not there already, just to read up on some of those reviews. The spacer does come along with all the necessary hardware and gaskets needed for the installation and best of all does not require a tune. Speaking of the install, this one is pretty much as easy as it gets, you’ll want to first remove the factory throttle body, install the spacer to your factory intake manifold and then reinstall the throttle body to the spacer itself. We do call this one an hour on the site but don’t be surprised if you get it done a little faster. Either way if you do have any questions or concerns, or need some help installing the throttle body spacer, feel free to give us a call or shoot us an email. So if you’re looking for an easy to install, inexpensive part that’s only going to help your performance as more parts are added, then you have to check out SR Performance’s throttle body spacer available right here at

        Cheap add on.

        This went on my stock 2005 GT. Throttle response seem better. Probably won’t see much HP until cold air is installed. Easy as far a bolt one could get. Bolts were about 8th inch to long. Adding a thick washer helped take up space. Over all for 40 bucks a great buy.

        Fast easy install

        The spacer was very easy to install and looks to be decent quality. Can't really tell any performance change, but under light loads the MPG seems slightly better.

        WARNING: Bolts might be a bit too long

        Overall... I like this product... especially for only $40... as compared to other more expensive options ( perhaps they are charging extra for the colored finish?? ). Even with my criticisms below, it gets 4-stars because I got what I expected from it. Fun to work on my car... and a little "whistle" added to the acceleration. Performance... I gave it 2-stars because I think it's misleading... I Seriously Doubt there is any "noticeable" power/performance gain from this spacer, even when it's installed with the most ideal conditions. It's "plausible" that it might improve throttle response... but I'm willing to bet that everybody who installs this, just as I did, will also take the time to clean the Throttle-Body and the Mass Air Flow Sensor... which, will increase throttle response all by themselves... especially if you disconnect the battery and let the computer reset as well (like you are supposed to). FIT - 3 stars... bolts are too long... add washers. It says "straight forward bolt-on installation"... the new bolts bottomed out before they even tightened down on the lock-washers that came with it. I've seen several reviews where people had engine problems after the install, and I'd bet some of them might not have noticed if that happened. If it can't tighten down... there's no seal... obviously you're not supposed to wrench-down on this thing, but it needs to be tight enough to create a seal for that thin gasket they included. In any case, I added a few washers to each bolt.. problem solved. Simple solution, but I shouldn't have to do that.

        The only problem was that the bolts were a 1/2 to long. Had to grind them down in order to fit. Other then that, I am pleased with this product

        This throttle body spacer made a difference in my peddle response. I was really surprised in the difference in HP also.

        Throttle Body Spacer

        If you have an intake cover on your 4.6 you will have to remove it completely or modify it to fit with the Throttle Spacer. I also had problems with the blots that came with it. They were to long so I had to use washers to take up that extra space. Other than those two issues i am very satisfied with the performance. There is quicker throttle response and maybe a small gain in HP.

        Bought it 'cause it was $29, though I might as well. It's been pretty well debunked already, but obviously it provides no power gains. My biggest gripe is that it seems like the bolts were too long, the ends of the throttle body started to bulge.

      5 Top Rated Questions

      will the SR performance throttle body spacer fit a bbk 62mm throttle body? do the bores on the spacer match the bores on the bbk throttle body 62mm?? or are they different because the spacer fits a stock throttle body with 55mm bore?? i know V6 models do from prior experience but is it the same on a GT?? need to know before i buy either. thank you!

      • The bore size on this spacer is designed for the stock throttle body only. Using this spacer with the 62mm aftermarket throttle body would actually restrict your airflow and negatively affect your power gains. Hope this helps!

      Will this fit on the Ford racing intake that you guys carry?

      • Yes it does. I replaced my orginal intake from ford with the ford racing intake this summer and it works perfect. I have pictures posted on the intake section and you should be able to see the spacer in the pics.

      • Nope, threw it on my 06' and no check engine lights.

      How does this improve performance?

      • The throttle body spacer is based on the theory that air entering a chamber will have a greater velocity and more mass if spun. The helical groves on the throttle body spacer are designed to make the air spin, thus delivering a greater volume of air to the engines cylinder. This in turn, increases the power of detonation by adding more air to the fuel/air mixture. Additionally, on older model Mustangs with throttle body injection, the swirling air mixes the air and fuel much better, providing a more consistent spark and hotter detonation. More air & a stronger detonation = more power.

      I recently purchased this item for my 2010 Mustang GT. After I installed it I noticed that the Powered by Ford engine cover that goes over the intake manifold would no longer fit on top of the engine. Is there anyway to get it bolted back on or is it just something you have to forfeit when installing a throttle body spacer ?

      • We have seen the SR Performance Throttle Body Spacer cause fitment issues with the engine cover, typically when the bolt heads come into contact with the engine cover. If this is the issue you are experiencing, a set of upper bolts with a lower profile bolt head will correct this. If you are having a different issue than this, please contact our Customer Service department so that we may best assist you.
