Easy fitment and power improvements throughout the RPM range even without any
fueling modifications [see dyno graph]

The Jetprime velocity stacks have been developed for the Aprilia RS 660/TUONO
660 to improve the air intake during the phases of opening the throttle.

The bell mouth shape allows a reduction in air turbulence during the suction
phase, improves the air intake from inside the air box, facilitates the intake
and reduces the response time of the engine especially when you have a fast
opening of the throttle.

The shape and length of the velocity stack has been developed by Jetprime
design department to give improvements through the engine at different RPM, to
increase the suction strength and to improve the coverage at low engine
speeds.

The velocity stack is mounted inside the air box and have been designed by
Jetprime and manufactured from aircraft quality 7075 T6 aluminium using some
of the most modern CNC machinery available.
