      Improve Engine Performance. Unleash your V6 Mustang's hidden power with a SR Performance Throttle Body Spacer. The SR Performance throttle body spacer increases plenum volume to improve the low to mid range torque from your Mustang's stock 3.7L engine, with noticeable gains seen between 800 to 2500 RPM.

      Better Fuel Economy. The SR Performance Throttle Body Spacer not only improves the performance of your Mustang, but with its unique “Spiral Bore” design it also improves fuel efficiency. The Spiral Bore "spins" the incoming air for improved atomization of the air fuel mixture for better combustion.

      Application. The SR Performance Throttle Body Spacer is specifically designed to fit the 2011-2017 3.7L V6 Mustangs with a factory throttle body installed. No tune required.

        Throttle body spacer

        Easy install and great addition. I have it setup with a cold air intake so the performance is way better. Comes with a new little tube but I didn’t use it no need I guess.

        There is not much to say. I did the spacer, the 73mm Throttle Body, and an air intake, very easy installation (less than 1 hour)... Way better performance after upgraded.

      Please excuse the ignorance, but what exactly is this good for? I am not quite sure what this is exactly, I just find it intriguing because it says it improves performance. Also Will this work with the aftermarket cold air intake?

      • By increasing your plenum size behind the throttle body, we have found that this was able to create a little bit better of an airflow which ultimately lead to a small increase in power in the low to mid RPM range. I personally would recommend rather than purchasing this item, putting this money towards the BBK 73mm Throttle Body (11-17 V6) Item 56146 The stock throttle body size is 68mm and by increasing your size throttle body you are now allowing more air to flow into the motor which ultimately leads to more performance throughout the entire power curve!

      Will this work with a bbk throttle body ?

      • This throttle body spacer will only work for the factory throttle body.

      Compatible with Airaid CAI? Is this spacer compatible with the Airaid CAI and BBK Throttle Body?

      • Yes it is

      Hi I am just wondering why this SR spacer will fit with a Airaid CAI, But the Airaid spacer will not work? What is the difference? Sorry I'm a newbbie to all this!! I have a 2014 3.7 and would like to start with these two MODS. If I can?

      • Both the SR Performance Throttle Body Spacer and the Airaid Poweraid Throttle Body Spacer are physically able to be installed with a cold air intake, however this will move the throttle body outward, thus moving the mounting location for the CAI, because of this you can have fitment issues, or create a restriction if the couplers Kink. Airaid does not recommend this with their CAI, whereas SR Performance will advise it is possible, but additional care must be made during install to ensure everything is correct.

      Hey I am just kind of confused because I was looking at the BBK 73mm throttle body and one of the top rated questions that was answered was some one asked if there was a throttle body spacer that would fit that throttle body. And the answer that was posted by y’all said yes there was was one and this was the model number that was claimed to fit the 73mm BBK throttle body but then I came on the description of this throttle body spacer and it says it strictly only works with stock throttle bodies? I am just kinda confused is all because the FAQ answer for the question about finding a spacer was linked to this one but then on here it said it will only fit sock. Any help would be appreciated thanks!

      • This spacer is for stock throttle body.
