In Mustangs with electronic fuel injection, like your 2019, have a throttle body. When you press the gas pedal down, the butterfly valve opens, allowing air to reach the engine. How much it opens depends on how hard you're pressing the pedal. And in that way, the engine gets the right blend of gas and air.

Getting the right air/fuel ratio not only improves performance, but it also helps keep your engine functioning. Too much air or too much gasoline can cause serious issues. That's why it's important to not just get a larger 2019 Mustang throttle body, but to get a high-quality one that will keep the balance.

Many Mustang enthusiasts opt to upgrade their GT with parts intended for the GT350 or Bullitt Mustang. Fortunately, with the right accessories, these throttle bodies can deliver improved performance to your GT Mustang as well.

2019 Ford Mustang throttle body spacers can be used to create a better fit, but they also can be added to improve horsepower. By giving air and fuel extra space to mix, your engine will get a perfect ratio. Though 2019 Mustang throttle body spacers are small, they can add 4-5 horsepower to your build. While that may not sound like much, every little bit helps.

Greater air capacity means you'll have the ability to improve your engine even more. Which is one of the reasons why a throttle body upgrade is a great modification to make at any point in your build.
