      Review & Installation Video

      Hey I’m Justin with, and this is my quick look at the SR Performance Intake Spacer fitting all 96-04 Mustang GTs. SR Performance is a company that prides themselves on making high quality but budget friendly performance and suspension components, for a wide variety of different Mustangs. If you want to stay up to date with all the latest SR products released for your ride, in addition to an overview of each product, you have to subscribe to our YouTube channel if you haven’t done so already simply by clicking on the banner below. So the idea of spacers actually originated back in the old school carborator days where raising the carb off the plenum would increase plenum volume and allow for more even fuel distribution. The idea of the SR spacer here works off that same principal, by boosting plenum volume you should see a small bump in power. I’m not going to sit here and tell you this product alone is going to give you 15 horsepower at the rear wheels because honestly it won’t, however it is a great mod for the price that compliments those other basic bolt ons such as your cold air intakes and your exhaust but really shines whenever you add a supercharger or turbo charger into the equation. Either way, I really encourage you to hear what other 2 valve owners are saying about this product, you can do so by simply clicking on the banner below to head back to the product page at, and read up on some of those reviews yourself. The SR Performance spacer here is designed to work with both factory and aftermarket throttle plenums and intakes and is made from 100% solid billet aluminum. It also comes with all necessary hardware and gaskets to get the job done, and best of all does not require a tune. As for the install itself, it is pretty straightforward and should only take you about an hour from start to finish. You will of course need to remove your factory throttle intake first, attach the spacer to your intake manifold itself, then reattach your throttle body or throttle plenum to the actual spacer. Again, very straightforward stuff, but if you should need any help or if you just want to talk shop, you can always shoot us an email or give us a call at any time. So if you’re looking for an inexpensive and easy to install part that’s only going to help your performance as your mods grow, you have to check out the SR Performance throttle spacer, available right here at

        5 2002 GT - JawneyStarlight Installation Time: Less than 1 Hour

        SR Intake Spacer

        Simple installation and direct bolt on. Just be patient with everything and you will notice some good acceleration on the top end. Only thing I added was nuts for security on the 4 bolts holding the throttle body onto the intake, and they also added some extra clearance. Did not use any gaskets because they were too delicate, but car runs and sounds amazing. Performance wise it added the feeling of smoothness no more harsh backlash with my 78 mm BBK throttle body so I would say this is a must have it that's what your running. EGR valve was the only complication... but with the right tools placed in the correct positions you will get it perfect. Just have a pry bar pushing against the fire wall to move the valve a little to the left then a wrench to move the valve up pushing against a hard surface. Do NOT disconnect the EGR tube from the valve it will be a little more difficult to line everything up. Other than that don't over torque the bolts on anything you take apart just snug them down and give a little twist... most of bolts and threads are not enforced for pressure.

        Great Addition!

        Added this spacer with a new TB and plenum. You can really feel the difference! Would recommend this to anyone. Plus you get a little whistle on revs! Ha

        Spacer plate

        For the money it’s worth it! With aftermarket manifold and throttle body if you have stock hood might be a issue

        3 2003 GT - 03blackGT Installation Time: Afternoon

        Beware of Bolts Supplied

        The longer bolts supplied are not a quality set of bolts. When tightening, the last bolt snapped off leaving me with one option. Take it to a mechanic to have it removed and a better grade bolt to be installed. A simple job ending up taking extra time and money due to cheap bolts. The spacer itself looks nice under the SR throttle body.

        Fits Good, Easy Install

        Spacer fit perfectly. Tight fit with stock EGR valve but nothing major to be concerned with. Looks good and there is a slight change in exhaust tone as well as slight engine whistle.

        Good add on

        Works awesome with a 70mm t/b and AIRAID intake. Definitely notice a gain in torque and helps with the airflow....remember your engine is a giant air pump...more it can be breathing....better it can perform!! Tune not needed....but suggested if you are wanting max hp gain.

      5 Top Rated Questions

      Does this spacer work with the BBK 78mm throttle body?

      • Yes. Install this spacer between the upper intake plenum and the intake manifold.

      Will this give any gains, and if so how much, with a 70mm BBK TB and a factory plenum on a 99 GT? K N short ram intake.

      • This will gain you power still and has been dyno proven to 2-7 hp.

      so if i have cold air intake along with this will it improve my overall acceleration?

      • Just about any mod you do to your Mustang will help acceleration. This keeps the air flowing into your engine cooler by keeping it farther away from the heat of the engine thus giving you more power. The power gain will be very minimal though, so don't expect to "feel" the difference. But little mods like this add up when you start getting more mods like CAIs and Tuners.

      Would this work with the sr strut tower brace ?

      • This spacer WILL work with the strut tower brace and the factory upper plenum. HOWEVER, this along with an aftermarket upper plenum will be a very tight fit. I installed this spacer with a Trick Flow 75mm upper plenum (P/N TFS-518B0001) and the throttle position sensor just BARELY fit behind the strut brace. I have a 96 GT, so an 02 GT may be a little different clearance wise.

      DO YOU NEED TO MODIFY THE STOCK HOOD? Will this spacer interfere with the hood closing okay? or do i need like a cowl hood?

      • No modification necessary - this can be used with the stock hood without any clearance problems.

      In the old, carburetor days, adding an intake spacer by itself may have provided some small increase in horsepower and torque, but those gains occurred at a higher rpm range as compared to the stock condition. Is this true for the SR intake space on a 97 4.6 GT? Will there be a gain at some higher rpm range while producing a slight loss of HP and torque at off-idle thru the lower rpm range? 1 answer
