Designed for racing use and modifed engines, the shape of these special velocity stacks provides an improved venturi effect compared with the standard velocity stacks and is perfectly connected with the throttle body.

The injector support is very thin and aerodynamic, so as to disturb the incoming air flow as little as possible.

They are made of ergal 7075-T6 with the most modern CNC machines and are designed and manufactured entirely by Jetprime.

They are mounted without any modification inside the air box using the petrol tube and the standard injectors.

Installation is simple, but fitting by a qualified technician is recommended. Full potential is achieved when they are used together with a dedicated mapping which has been professionally prepared by an expert.
