    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.

    Hi, I've read all the reviews about the product and I'm confused, some say It improves performance and sounds great and some say the opposite. I know It's a cheap mode, but for me (in Spain) customs are expensive, so, honestly , it's worth it or not? I dont expect a supercharger improvement of course. Thanks in advance.

    • Throttle body spacers are great for increasing fuel economy, adding additional volume to the intake, and crating additional power. However, throttle body spacers will generally only add about 5+ HP at most. if you are looking for quick, easy power, a throttle body spacer will be for you. If you are looking for a little extra power, I would recommend investing in a cold air intake, throttle body, or tuner.

    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.

      Breathe Easy

      Was looking for a remedy for the super hot AZ air that gets sucked in my CAI and bogs down throttle response. Well, this is a good solution. Not sure if it improves gas mileage yet, but it does what I need it to do. Oh, and I don’t hear the whistle some have mentioned, but my exhaust likely drowns it out.

      Throttle Body

      If your expecting for it to whistle as some reviews have stated, it doesn't. At least I did not hear it. I did notice a slight increase in low end, but the part that I was interested in was MPG. I broke 25.2 mpg on an eight mile run at 85 mph. Not bad, but am greedy and want 27.2 mpg. will find out soon on a 400 mile run. Money will spent if your looking for increase in mpg.

      Good product

      I can tell the throttle responce is much better and crisp , i didnt check mpg to see if there is a difference but maybe 3 or 5 mpg is better than nothing so overall good product.

      Spacer

      Works as they say it does. Improved mpg a little bit, and a little intake swirl type noise below 2500rpm. Leaned out my long term fuel trims about 3-5. This was installed on my 14 GT/TP/6spd, not my current 18 GT/TP/A10. 18's have a larger T.B.

      Works like a charm on my 2018 Orange Fury!

      I hear the swish! LOL and yes I noticed a pretty big increase in the lower rpm torque. I suspect its working in conjunction with my JTL CAI but it’s even idling better now. Best $99 I spent so far. A little more difficult to install with the CAI (Closer to an hour) but just a few extra bolts. ;-)

      I could not hear the whistle because of the sound of my car's suction and the sound of the rear, but the response improved at low rpm. Initial response improved.

      SR Throttle Body Spacer

      Bought this hoping to gain a little bit of low end help. That’s about what it delivers...a little bit of torque from idle to around 1500 RPMs.

      It is a very simple and easy bolt on. I cannot hear any “whistling” noise that has been mentioned in reviews and I can’t really tell a difference in performance boost but it comes with everything you need to install and again it is very simple and easy to install.

      SR Throttle Spacer

      Perfect fit, no problem installing since I did this when I installed my KandN CAI. Can't really comment on the performance gain since I installed the same time as my CAI. Since I have a 2013 GT it would be impossible to notice a few HP gain. Have not driven it that much since installation and also can't comment on any increase in gas mileage. Sales pitch sounds like a good idea.
