Intake Air - Intake Manifold Tuning (IMT) Valve System(R20A5) (2013 2014 2015)

Engine power is adjusted by opening and closing the intake manifold tuning (IMT) actuator. When the valve is closed, there is high torque at low engine speed. When the valve is open, there is high torque at high engine speed. Every time the ignition is turned to ON mode, the PCM turns the IMT valve back to its closed position.
