20 Best Throttle Body Spacer (2022 Updated)

A throttle body spacer is a device that is installed between the throttle body and the intake manifold of an internal combustion engine. The purpose of a throttle body spacer is to create additional space between these two components in order to improve airflow and engine performance.

Throttle body spacers can be made from a variety of materials, but aluminum is the most popular choice due to its light weight and durability.

Conclusion

A throttle body spacer is an aftermarket accessory designed to increase the performance of an engine by creating more space between the throttle body and the intake manifold. The increased space allows for more air to flow into the engine, which can lead to more power and better fuel economy.

There are many different designs of throttle body spacers, and they are made from a variety of materials, including aluminum, plastic, and even stainless steel. There is no one-size-fits-all solution when it comes to choosing a throttle body spacer, and the best option for your vehicle will depend on your specific needs and goals.

If you are looking for a simple and inexpensive way to improve the performance of your engine, a throttle body spacer is a good place to start.
