    • WHAT IS THE AIR4ORCE TUNABLE INTAKE? The AIR4ORCE is a tunable intake system via interchangeable velocity stacks, that completely replaces your stock air boot.
    • WHAT DOES THE AIR4ORCE INTAKE DO? First it creates more horsepower due to the larger air volume. Second it allows the user to change the power characteristics to suit track conditions and rider preference.
    • WHAT CAN I EXPECT AFTER INSTALLING THE AIR4ORCE 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 INVOLVED WITH INSTALLING THE AIR4ORCE INTAKE SYSTEM? Remove subframe (using directions provided in your motorcycle manufacturer's owners manual), remove rubber boot between airbox and carburetor throttle body, and replace with the AIR4ORCE.
    • WHAT'S INCLUDED WHIN I PURCHASE AN AIR4ORCE INTAKE SYSTEM? Moto Tassinari product line brochure, Moto Tassinari and AIR4ORCE decals, detailed installation instructions, two velocity stacks, AIR4ORCE tunable intake system and hose clamps and gaskets where necessary.

    What Are Velocity Stacks? The most unique feature of the AIR4ORCE tunable intake system is the ability to fine-tune the power delivery via interchangeable velocity stacks. However that concept might be a little unfamiliar for some not as experienced with four-stroke motor performance. We'll do our best to explain the concept below: A velocity stack is a device of differing lengths which is fitted to the air entry of an engine's intake system, carburetor or fuel injection. It is designed to:
    • 1. Allow smooth and even entry of air at high velocities into the intake tract with the flow stream adhering to the pipe walls.
    • 2. Modify the dynamic tuning range of the intake tract by functioning as a resonating pipe which can adjust the frequency of pressure pulses, based on its length, within the tract.
