Intake System

What can I expect after installing the AIR4ORCE tunable intake system?

Depending on the chosen velocity stack installed in the AIR4ORCE you will gain better throttle response and bottom and mid-range power (with longer velocity stack), or better throttle response and mid-range to top (with the shorter velocity stack installed).

WHAT'S INCLUDED:
===========================================
AIR4ORCE tunable intake system, two velocity stacks, Moto Tassinari
AIR4ORCE product line brochure, Moto Tassinari and AIR4ORCE decals,
detailed installation instructions, and hose clamps & gaskets where
necessary.

There's a reason the AIR4ORCE tunable intake system was named, 2012 Product of the Year, by Transworld Motocross magazine—because it works.

The AIR4ORCE provides more horsepower by increasing the volume over a stock airboot and then allows you to tune the power delivery to suit track conditions or rider preference via interchangeable velocity stacks. There's simply nothing else like it out there, which is why you see it being run by many of the top racers and teams.
