The performance of a car can be disappointing for some people, so they look for ways to improve it. Unlike people, machines can’t be controlled by talking to them. To improve their performance, you’ll need to alter or add new technology.

The horsepower and torque of a vehicle are the two primary performance metrics. Since the two are interrelated, improving one will have a positive effect on the other.

Throttle body spacers are an easy way to boost your car’s horsepower. As a result, we have arrived at our subject. A throttle body spacer adds how much horsepower?

Up to 18 horsepower can be added to your car’s performance by installing a throttle body spacer. Adding 25 ft-lbs of torque could potentially improve performance while also lowering fuel consumption.

Understanding what a throttle body spacer is, how it works, and which vehicle types it can be used on can help you better appreciate the performance boost that may be obtained by installing one. Find out if installing this spacer will have an impact on the performance of your car by reading this article.

What is a Throttle Body Spacer?

It is a piece of metal that is used to modify the flow of air into the engine’s intake manifold. There are two screws holding it in place on the throttle body’s back.

In order to save gasoline and enhance horsepower and torque, a throttle body spacer should be installed in a car.

Do Throttle Body Spacers Work?

Fuel combustion cannot take place without air in the combustion chamber of your car’s engine. Therefore, the more air in the combustion chamber, the more fuel is consumed and this results in a better level of performance from the engine.

The engine’s airflow intake can be controlled by the car manufacturer. When it comes to airflow intake, though, some people adjust it in order to improve their vehicles’ performance.

Yes, that’s correct. An efficient fuel burn is achieved by allowing more air into the combustion chamber via the throttle body spacer. When fuel is completely consumed in the engine, it indicates that the engine is in a healthy state, which results in higher horsepower and torque. In addition, because no gasoline is wasted, the vehicle’s overall fuel consumption is reduced greatly.

You can boost your car’s performance by adding a spacer to the throttle body, which is both simple and inexpensive.

Does Throttle Body Spacer Increase Throttle Response?

That’s correct. With the addition of a throttle body spacer, the amount of air flowing into the combustion chamber increases with ease. As a result, the engine’s response time is improved because it is not taxed.

Can you use a throttle body spacer with a cold air intake?

Spacers are permitted in cold air intakes. When the intake track length is increased by a few centimeters, the kit will not have any problems with it.

Benefits of Adding Throttle Body Spacer

  • Increase in Horsepower
  • Increase Fuel Combustion
  • Increases Torque Response of the Engine
  • Increase Vehicle Performance
  • Enhances Engine Durability

If the engine is underperforming, mechanical issues are more likely to occur. Because of the amount of power necessary to keep the engine operating, the various components are prone to damage and wear. However, the installation of a throttle body spacer improves the engine’s durability by allowing various sections to do their functions more efficiently without straining.

It’s vital to keep in mind that adding spacers isn’t always beneficial. Because of this, it is important to know what type of engine these kits are compatible with before deciding to install a spacer and reap its benefits. Which engine type does a throttle body spacer fit?

Type of Engine that can Benefit from Throttle Body Spacer Addition

This method of increasing engine performance is best suited to older engines, specifically those with fuel installation systems that allow gasoline to flow directly into the throttle body and mix with air before it enters the combustion chamber.

Cars with a carburetor system can also benefit from installing a throttle body spacer. However, if your car is equipped with a top-of-the-line system such as a multi port fuel inoculation system, this alteration will make no effect. Decide on your car’s engine make before you buy the kit, therefore.


Even small alterations to a vehicle can have a significant impact on its performance. The most common, easiest, and most economical approach to boost a vehicle’s performance is by installing a throttle body spacer.

It adds roughly 18 more hp, 25 more lb-ft of torque, and reduces the amount of fuel consumed.

However, not all engines can take advantage of this simple adjustment. Older engines with carburetor or fuel injection systems are the only ones that can benefit. Before you invest in this performance-enhancing approach, be sure your car’s engine is in good working order.
