Simple installation for anyone.
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.

Throttle Body Spacer Installation
Simple installation fitment was great. Un-clear on any performance gains.Helpful (0)

It is okay
It is ok there is a slight difference it is worth the price.Helpful (0)

I waited to install with my CAI. And after reading comments I was a little concerned. I’ll be the first to tell you I was not disappointed. I used this spacer with an Airraid CAI and the throttle response was amazing and definitely puts your head into the seat. I do notice the ‘whistle’ soundHelpful (0)

It did add a nice soft windy sound, got a couple comments thinking it was boosted LOL, but not too much difference in performance, i was expecting the throttle a little bit more sensitive.Helpful (0)

I don't think it adds any horsepower if it does it adds like one but it makes a cool whistling sound so I guess it was worth the 40 dollars.Helpful (1)

More Low End Punch
Pros: more torque in low RPMs, easy 20 minute install (I do not have engine cover installed), quality construction Cons: price, have not noticed any increase in MPGHelpful (0)

Was on sale...
Got this only because it was on sale. I noticed no difference in sound or performance.Helpful (1)

Seems to work
I was a little sceptical about ordering one of these as I was not a believer they made any difference, being the price was reasonable and after reading the reviews I decided to pull the trigger, after a very easy installation the throttle does seem to be a bit more responsive nothing else however was noticed, will monitor fuel consumption and see if that changesHelpful (0)

Bang for the Buck
A nice piece with quality machining. Easy to install with a nice low end feel and gain.Helpful (0)
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.
Would this fit with the K N Air Charger Cold Air Intake installed?
The SR Performance Throttle Body Spacer (11-17 GT) will fit with this cold air intake or any other cold air intake.
Compared to the Airaid how thick is this spacer?
Both throttle body spacers are essentially the same size in terms of how thick they are. They just have slightly different designs due to the different brands.
Will this product fit with a bbk 90mm throttle body spacer
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.
Since this product is spiraled does it have to be installed in a certain direction, I have not seen anything relating to this or can it be installed backwards.
This product does not need to be installed in a certain direction.
Yes, it absolutely does fit the Boss 302 Intake.
We would recommend using the one that comes with this, but yes, typically you can reuse that spacer if you choose to.
Hello! Unfortunately these gains do not multiply by adding multiple throttle body spacers!
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.
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.
This spacer will complement the extra air you are getting from the CAI at low speeds. The spacer is most effective at lower speeds when the air speed is slower. The slight "redirection" at the (curved) 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 - turbulence helps.
The straight line air velocity will not change. The spacer only induces a "swirl" to the air (mostly the edges) coming in. Since one spacer already swirls the air, another one is not needed. Two spacers will not swirl the air twice as fast because the "pitch" (groove angle) is the same on both. In fact, inducing too much "swirl" reduces the forward momentum of the air - needed to rush down and pick up gas to carry to the cylinders.
No this is not CARB certified.
This can be installed in any orientation that allows all four bolts to be installed as they were with the stock configuration.
The required gasket is included.
