What is velocity stack?

A velocity stack is a device used in internal combustion engines to improve the airflow into the engine. It is typically a cone-shaped or trumpet-shaped component that is placed on the air intake of the engine. The design of the velocity stack helps to smooth and increase the flow of air into the engine, which can result in improved performance and increased horsepower.

Velocity stacks work by accelerating the air entering the engine, which can help to create a more efficient air/fuel mixture. This can result in improved combustion and better engine performance. Additionally, the smooth shape of the velocity stack helps to reduce turbulence in the airflow, which can further improve engine efficiency.

Velocity stacks are commonly used in racing and high-performance applications, where maximizing engine performance is a priority. They are often used in conjunction with other performance upgrades, such as high-flow air filters and exhaust systems, to optimize engine performance.

Overall, velocity stacks can be a valuable upgrade for those looking to increase the performance of their vehicle's engine. However, it is important to note that the benefits of velocity stacks may vary depending on the specific application and engine setup.
