SFI SYSTEM


  1. FUNCTION


    1. The Acoustic Control Induction System (ACIS) uses a rotary type intake air control valve to divide the intake manifold, creating 2 stages. The intake air control valve is opened or closed to vary the effective length of the intake manifold in accordance with the engine speed and throttle valve opening angle. This increases the power output in all ranges from low to high speed.
