    Review & Installation Video

    What's going on guys? Adam here with, and I'm bringing you my review of the Airaid Poweraid Throttle Body Spacer for all '11 to '16 GT Mustangs. This Airaid Poweraid Throttle Body Spacer for all '11 to '16 GT owners is a very affordable and an easy install part that'll give you a small bump in added power, and also in throttle response for your Coyote-powered GT without having to purchase a whole new throttle body. To jump right into the function of the Airaid Poweraid Throttle Body Spacer, it's meant to provide added air support for the air going into the intake manifold. For those of you with the stock sized throttle body who might be interested in this spacer, in all honesty, you don't want to expect crazy power gains that are going to knock significant time off your quarter mile. Airaid does let us know, however, that you can expect a little bit of power gains as far as low end torque and low end throttle response, somewhere between the 800 and 2,500 RPM region. I want to touch on what the Airaid Poweraid Throttle Body Spacer is actually made of. This is where you get the idea of what it actually does. It's machined from high quality aircraft grade 6061 billet aluminum to resist corrosion and wear. It also comes in a red finish to give it some under the hood styling. Included in the kit is all the installation hardware that you need, so you can actually trash a lot of the old throttle body hardware that you have already. You'll notice that in the construction of the Airaid Poweraid Throttle Body Spacer there's a very unique design in the center. This is the helix bore design, which is like threading, which acts as like a turbine, thrusting and rotating the air into the intake manifold. That's where you see the low end power and a small bump in throttle response. One of the other things I should mention about this design is when it's installed, you can actually hear a whistle sound coming from the throttle body, which is the sound of the air passing through the helix bore design. Airaid also tells us that this helps maximize fuel efficiency, which can actually save you money at the pump in the long run. Now this is another one of those cases where you don't want to expect crazy miles per gallon gains, but what you can expect is a superior atomized mixture of air to fuel ratio all the way to your combustion chamber. This in turn will help you save a little bit of money at the fuel pump. You'll notice that this throttle body spacer is not the only one that's out there. However, aside from the red anodized finish, this is the only throttle body spacer that we offer on our site that has a CARB EO number, which basically means it's 50 state legal. That's beneficial for you guys out there in strict emissions states like California. As far as the materials go, you'll notice that this Airaid Throttle Body Spacer comes in at the thickest of the site, which is about one inches thick, whereas the other ones come in at about three quarters of an inch thick. That little bit of extra thickness allows for more threading, which allows the air to go faster through the intake manifold. Price wise, you'll also notice that this is a little bit more expensive than the other options on the site, but not by much, coming in at the $130 mark. Installation for this spacer is extremely straightforward. You can get it done start to finish in just about an hour with an 8 millimeter, 10 millimeter socket, flat-head screwdriver, and at least a 3 inch extension for your ratchet. Installation for the Airaid Throttle Body Spacer is going to be about the same for the '11, the '14 and '15, '16 Mustangs. You're going to start with taking off the intake manifold cover, disconnecting the cold air intake and the three tubes that connect to the cold air intake, which might actually require the use of pliers. When you're removing the throttle body, you'll have to loosen the clamp on the coupler holding it to the cold air intake. Once that's off, you can use a 10 millimeter and a 3 inch extender ratchet to remove the 4 bolts that are holding the throttle body in place. Once you get those off, take the throttle body out and place it to the side, and discard the rest of those bolts, because the throttle body spacer comes with replacement hardware. Once you have the throttle body off for the installation of the new spacer, you'll put the washers over the bolts, the bolts through the throttle body, the gasket over the bolts, and then the spacer over the gasket, in that order. After making sure everything's lined up properly with the manifold, you'll want to tighten the 4 bolts with your fingers, and then the 10 millimeter socket. Remember to make sure all the plugs and tubes are back on the cold air intake when you're reconnecting that. And then you want to place the manifold cover back in place, reconnect the negative terminal on the battery, and you're good to go. With all said and done, you're looking at about one out of three wrenches on our difficulty scale, making it an extremely simple installation for anybody in their driveway. Now, I'll be the first to admit, you don't want to expect crazy gains in the way of horsepower and torque, but according to Airaid, you can definitely see some gains in throttle response and even fuel efficiency. If this sounds like something you'd be interested in, you can pick yours up right here at

    Better Performance and Fuel Economy. This easy to bolt-on Poweraid Throttle Body Spacer from Airaid was developed to improve throttle response and unleash the hidden low to mid-range torque hidden in your Mustang's 5.0L Coyote engine. After installation you will see notable torque gains between 800 to 2500 RPM. This Throttle Body Spacer not only improves the power and performance of your GT Mustang, but with its patented “Helix Bore” design, it also maximizes fuel efficiency saving you money at the gas pump. The Helix Bore creates a spinning action to the incoming air to provide superior atomization of the air fuel mixture for better combustion.

    Aircraft Grade Billet Aluminum Construction. Airaid manufactures their PowerAid Throttle Body Spacer from the highest quality, aircraft grade, 6061-T6 billet aluminum available. CNC machined to precise specifications, this Throttle Body Spacer is completed in red anodized finish for great under hood looks and long lasting corrosion resistance.

        Hello, According to the video, this product has a CARB EO number. But it appears it only applies up to the 2014 Mustang GT, and doesn't address the 2015-2017 model years. Does this means it's not O.K. to install in a 2015-17 Mustang GT? 1 answer

            Sounds Excellent

            Put simply, Airaid TBS CAI = the best noise! The whistle is subtle but sounds excellent especially in the 1500-3000rpm range... if you’re going to purchase the CAI, this product was worth the money for the sound in my opinion. Power gains aren’t entirely noticeable but throttle response, especially on the low end, is better and the sound is nice

            3 2019 GT - RandyC Installation Time: Less than 1 Hour

            Took less than 25 minutes to Install

            It only took about a half hour to install because I had to disconnect the battery terminals, strut tower and engine cover prior to Install. I did not hear a whistle, I did not notice any better throttle, the car actually felt more sluggish if I'm being honest and I hear louder ticking now. I only bought this for better mpg which I have yet to do a hw trip to compare. There was no flow marker on the spacer but it did say "throttlebody side" so it should be installed in the right direction. I'll give the car time to relearn and see if anything improves.

            well, just as advertised I didn't expect much gains from a horsepower standpoint, I assure you I got a very good bump in my launches. I beat up on a Hemi the next day and I know the spacer helped. great bag for your buck guy's believe me!

            doesn't do any kind of gain with the low end torque and doesn't give you any better mpg.

            Looks good, sounds neat, power gain (not sure)

            I installed this along with a Airaid Race Cold Air Intake and a Bama tune so determining performance gain for just this is impossible for me. It whistled at certain rpms or under load and gives it that "definitely not stock" sound. Is it worth the cost? I'm on the fence, but it should not be the first thing you buy if you're looking for performance gains.
