    Review & Install Video

    The SR Performance throttle body spacer is available for any 2011 and newer Mustang GT owner, who might be looking to increase their plenum air volume to improve their air/fuel mixture and engine combustion, basically, leading to a more efficient motor. Now, the install for this goes directly on top of your factory throttle body as a direct bolt-on, so we'll be giving it a one out of three wrenches on our difficulty meter. So expect more details later on. Adding a spacer like this to your throttle body basically just speeds up and increases the volume of air going to your plenum and manifold. Now, you may see small gains in fuel efficiency, and maybe even small, single-digit horsepower and torque number increases. But mainly, the big thing here is air optimization. Now, the spiral bore design you see inside the spacer here will actually help to thrust and spin the air going through the throttle body into the plenum, which is basically going to up that volume I just mentioned a second ago. Now, this is very unique to the SR Performance option here. Now, the other options on the market just use a solid inner circle, which may not be effective in this aspect. Now, that also causes a slight whistle sound under your hood, which basically just lets you know that it's getting the job done. This was CNC-machined from a high-quality billet aluminum, very durable stuff, and it has that brushed aluminum finish on top. It comes with everything you need to get the job done, including the four bolts, spacers, and the gasket you need to get it on that throttle body. Now, with that said, this is a great alternative, for just about $100, to a full throttle body, which you might not be ready to jump right into. With that said, if you have a bolt-on motor, you would definitely reap the benefits more from a full throttle body replacement, whereas this is for a stock motor mod. This one absolutely gets one out of three wrenches on our difficulty meter. I'd say a ratchet and socket set, and even a flathead screwdriver will absolutely get the job done here. All you'll need to do is use that flathead to unclamp, basically, the coupler on the factory throttle body to gain access more easily to the bolts available. Now, use that ratchet and socket set to remove the factory bolts and pull the throttle body off of the plenum a little bit easier. Once that's taken care of, you can slip the spacer in between the throttle body and the plenum, and use the new bolts in order to bolt it down properly. Once those are taken care of and the gasket is into place, you are good to go. That just about does it for me. If you're the owner of a 2011 or newer Mustang GT, you might want to check out the SR Performance throttle body spacer, which you can find right here at americanmuscle.com.

    Improve Engine Performance. Unleash your GT 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 5.0L 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.

    Billet Aluminum Construction. CNC machined from high quality billet aluminum the SR Performance Throttle Body Spacer includes all the necessary hardware required for a simple straightforward bolt-on installation.

    Application. The SR Performance Throttle Body Spacer is specifically designed to fit the 2011-2018 5.0L GT Mustangs with a factory throttle body installed. No tune required.

    G'day, This may seem like an odd question...but...if two of these spacers were stacked between the throttle body and the inlet manifold, longer bolts installed to cover the distance, would there be a multiply increase over one spacer?

    RexE

    • Hello! Unfortunately these gains do not multiply by adding multiple throttle body spacers!

    It says it fits factory throttle bodies. What other throttle bodies would it work on other then factory? Would it work on the 90mm TB?

    SixTimeChamps

    • The SR Performance Throttle Body Spacer is designed to fit the stock throttle body only. Using this spacer with a larger throttle body will cause interference because the larger throttle body valve will hit the spacer. When the valve hits the spacer, the throttle body will not open any further.

    Will this product fit with a bbk 90mm throttle body spacer

    MM

    • No. Throttle body spacers are for stock throttle bodies. The idea is they are the cheaper/easier option if you want better throttle response but can't afford/don't want to deal with the hassle of a new throttle body. An aftermarket throttle body will always give better gains but a spacer is better than nothing.

    Will using this spacer cause any sort of clearance issues with an Airaid CAI?

    Hessian5k

    • No, it will fit your CAI and actually make it more snug. It will give you the extra air you are getting from the CAI at low speeds and mid RPMS. The spacer effective at lower speeds when the air speed is slow. The spiral bore edges forces the slower air near the tube wall into the faster moving air in the center of the tube. For your CAI the air is slower than in a stock air tube - so the spiral of the air or "tornado effect" helps. Ive seen many review ragarding the Airaid CAI w/tune and results have concluded that the fitment wasnt an issue.

Throttle response is much improved at lower RPMs and I have already noticed improved fuel mileage. This is definitely the simplest mod for a noticeable improvement!

      Has some benefit....but...

      Been great debate on benefits of this, but my experience is it did help some on the lower RPM HP range. A dyno test before and after proved it. It didnt help with my fuel economy - tested 4 full tanks as comparison. As stated in the product description, its made for the STOCK throttle body. If you put on a larger TB like a BBK, the benefits become nearly null other than the "sucking" sound (again tested). These are typically the people that say its has no benefit. A CAI is also a requirement for worthwhile gain (you should get one anyway!). Either you put on a larger TB or this, but for 1/5 the price and about the same gain for a lightly modded car it was an easy decision. Know what mods work together before you buy. If you are going minimal mod - TBS, if going HEAVILY modded (F/I or new manifold/total exhaust makeover), then bigger TB.

      Do not drop one of the bolts down into the lower radiator housing. Unless you have one of those long, flexible magnets. Then, it's OK. Unless you have to drive over to your son's house to get it, then drive back. Takes forever to get that bolt out.....

      exactly what it said it would do

      I was a little skeptical when I ordered it but I figured I would give it a try. Install was very easy you can't really mess it up. I just installed it yesterday so idk about fuel efficiency but I could instantly tell a difference with the throttle response and little bit extra power.

      IT WORKED!!

      I ordered the SR Performance Throttle Body Spacer for my 2016 Mustang GT Convertible. It took me about 45 minutes to install. I also have a K and N cold air intake on my car. When I took the stang for a test drive I could tell that the TB spacer had increased low end take off power and had increased power all the way through the rpm range. It was worth every penny that I spent.

      I installed this with the candl cold air intake and tune combo, so i cant say exactly how much this effects throttle response etc, but all I know is, is that this is very easy to install. Took about 5 minutes and me being 17 years old with no experience on cars, that should say a lot.

      20 Minute Installation and Help Corrects Low End Throttle Response!

      I had a mechanic neighbor install this for me and it literally took him under 20 minutes. I took it for a quick spin and YES it does help the low end throttle responsiveness which was worse before the TBS install so I can definitely say it does help improve it. Whether or not it ads HP/Torque I can't say it does but YES as for the delay in throttle that the 5.0's are known for it really does help it!

      Does not fit 2011 GT with BBK CAI

      I was ready to install this part with my new BBK CAI. Did all the work for both mods at the same time only to find that the PCV hose on the driver's side will not reach the CAI with this spacer installed. In order to use this part with a BBK CAI a longer PCV hose is needed for the driver's side.

      Great on Tuned engine...BBK owner's, beware!

      The install simple, but the bolts (10mm, not 8mm like instructions say) were so tight around my BBK throttle body that I had to use a wrench like a screwdriver, making 1/4 turns max! It took WAY to long to install for having 4 bolts! The BBK owner's will be upset because of this flaw, since they have less room around the bolts than the Ford TB, they use allen screws. So you can use them like a screwdriver and screw them on in seconds. One of my bolts could not go on fully (bottom left) since I could not get torque with the wrench in a twisting motion, so modification was needed. I will still have to get allen topped bolts so I won't have issues with this in the future. With that sad install and still a need to replace the bolts....the car went completely crazy! If that was only 10hp/tq, I only need 10 more to get into the 11's with just bolt-ons! It's scary when you bunch it at 30mph, spins, and hits second sideways! Tires will be ordered sooner than expected.....bolts first though!!!

      Good low buck mod

      I have the FRPP tune on my 2014 Track Pack car along with the AirAid tube utilizing the stock air filter box. This thing IMHO added a little more air thrust and it was complimentary to my mix. A little more torque is evident as is overall slight power gain. Intake noise is increased a little. Gas mileage increase is negligible. This is a great low-cost mod, especially if you have my set-up. I recommend.

      Excellent workmanship, easy instal

      The first thing you will notice about the SR throttle body spacer is the quality workmanship. The TB aluminum spacer piece looks awesome and fits perfectly flush against the stock oem throttle body. Installation is straight forward, just take your time and you'll be done in around 30 minutes. As for performance, low end or top end, along with improved fuel economy as others have stated, I honestly didn't notice any changes with the TB installed. I also can't hear the whistle which is probably due to my cat-back exhaust :) . It's difficult for me to recommend this product and I simply purchased it based on the previous reviews so it must be doing something since most people recommend it. Just purchase this TB spacer with the mindset that you may not notice any improvements.

      Hit and miss

      Can't say it makes any more power and doesn't feel any different. I enjoy the added hiss under mild throttle, almost makes you think you got a small turbo. With a factory intake box this might be an easy install, however I have the roush cai and getting the pcv and other hoses connected to the intake back on can be a pain. The spacer moves the intake pipe forward just enough to give you trouble.
