PURPOSE: A dual-duct intake system with a variable valve is provided to reduce intake noise as a shield plate of a second snorkel is closed. CONSTITUTION: A dual-duct intake system with a variable valve comprises a body(200), a shield plate(300), a solenoid(600), and a pad(400). The rod(650) of a connector moves with the rod the of the solenoid to the back side. The shield plate is moves to the front side from a rotary shaft(320), and blocks an intake port(210) while the projection(310) of the shield plate moves to the back side. The pad blocks the space between the intake port and the shield plate so that the noise due to the suction of the air through a second snorkel is prevented.
