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.
