Review & Install 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

More Power. This SR Performance Aluminum Intake Plenum Spacer for the 1996-2004 4.6L 2V GT Mustang is a simple yet very effective bolt-on to improve the quality of the air entering your engine. By helping to better separate your throttle body from engine heat and increasing the volume of the plenum, you will easily gain 2-7 dyno proven rear wheel horse power.

Simple Install. This SR Performance Intake Spacer is constructed of solid half inch thick aluminum and comes complete with all the necessary hardware and instructions for a straight forward simple installation. 

Application. This Intake Spacer is designed for use on the 1996 to 2004 4.6 2V GT Mustangs and will fit with the factory intake or with an aftermarket cold air intake kit.

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

Will this work with these aftermarket parts? I have a Typhoon intake with Accufab throttle body and a BBK Cold Air Intake? I would like to keep adding bolt ons. Let me know ASAP thank you


  • Yes, this spacer will work with your Typhoon intake and accufab throttle body, I also recommend getting an Accufab Upper Plenum to go along with the throttle body you have and this intake spacer to get the most out of it.

Would this work with the sr strut tower brace ?


  • This will raise your intake 1/2". You should probably have at least 1/2" clearance between intake and your brace. You will have to go measure for clearance.

Gasket Does it require one or two gaskets


  • It just needs 1 gasket which goes on top. The intake manifold below the spacer has a round rubber o-ring which seals up to the spacer

Intake spacer gasket and cylindrical plug The install guide shows the gasket that comes with the intake spacer as going on the top side of the spacer. What about the bottom side of the spacer? Does it need a gasket too, maybe one that is all ready in the engine that we re-use or does it not need one and we still get a good seal? What about the aluminum cylindrical plug with a hole in it. The install guide doesn't mention it nor does it show up in the parts picture or description. Do we need it and, if so, how do we use it?


  • The top of the intake manifold has its own gasket that gets reused, the supplied gasket needs to go between the plenum and the spacer. The little cylinder is for mounting the plenum to the intake manifold. Since the plenum will be higher off the intake manifold this kit comes with new longer hardware. There are five bolts that hold the plenum down to the intake manifold, four around the base and then one that fastens the little "stability arm" that comes off the plenum toward the front of the car near the throttle body. This cylinder is a spacer that will go between this "arm" and the intake manifold for fastening it down.

Will I be able to install strut brace. Will it hit intake or air filter tube?


  • Depends upon the strut bar that you have. When I installed mine I had to add a spacer under the strut bar to allow clearance. I simply made spacers out of pieces of 1/4" flat bar with a hole drilled in it, I have the AM Stack Racing strut bar.

    Nice for a factory intake.

    I got this spacer to go with the SR throttle plenum the spacer looks like it has a 65mm opening like the factory plenum the SR has a 70my so it actually reduced the air flow into a after market plenum. Great for factory but to get 100 of the airflow with aftermarket plenum you will have to port the spacer a bit.

    Better then i expected

    I was always unsure about buying this product, most people said that it was a waste of money so i believed them and didn't bother with it. Then i went to wyotech and it makes sense, increase length of intake=more torque. Thats exactly what this intake spacer did, improved my torque, increased my throttle response also. It is def. worth it just buy it and see for yourself. AWESOME product.

    Good Product

    I installed this spacer on my 04 GT and i could tell a big difference in the sound and power at higher rpms. It took about an hour to install. A bit of advice, don't take off the egr but just slacken the bolts a bit so you will have a little bit of play. And make sure to line the gasket up right and it should fall right into place. It says use 2 people but you can do it by yourself, it just may take a little longer. Overall, I am impressed with it.

    Very Nice

    Although it was a little hard to get leverage on the EGR valve to line it up, once it was done, it was very nice. Mates really well to a cold air intake. 2nd gear has a noticeable difference in torque. Easy installation. Stays true to the old saying "10$ is a good deal for 1hp"

    I bought this spacer and it doesnt work very well with the BBK 78mm throttle body. The EGR valve doesnt want to line up with the throttle body when the spacer is in. GOOD PRODUCT. Not very compatible with aftermarket throttle bodies.

    Spacer issue

    Oh my God i thought I was going to snap the EGR bolt (The thing on the right side of the plenum) Very tight to bolt on becasue of the hieght change. I had to use a hammer to pry the EGR up to get the bolts in. Even then it was very tight. Also, I recomment being VERY carful when installing this becasue i accidently snapped a vacume line. (Red lines that look like wires).

    very nice

    i had installed one of these spacers on my previous mustang prior to installing the one on my current one, so i had a little bit of experience. I have a support bar that goes across the middle and it still only took 15 minutes to install, although i did run into problems with my egr valve not wanting to allow access. all i did was unscrew the two bolts holding it on and it allowed me to lift my throttle body up. instant gains in TQ

    Strut Tower Brace

    If you have a strut tower brace don't bother, the spacer won't fit because there isn't enough room between the raise TB and the brace.
