A velocity stack is a trumpet-shaped funnel fitted to the air entry of an engine's intake system, carburettor or fuel injection. This velocity stacks kit for Aprilia RSV4, improves the airflow to the throttle bodies, optimizing the length, taper, and shape of the stacks for both the front and rear cylinder banks. A significant power increase is obtained, starting from 9000 RPM all the way to the rev limiter, allowing all cylinders to breathe better and deliver greater performance. Created with advanced 3D printing technology, these stacks offer durability, lightness and precise installation. They perfectly fit with the standard airbox.
