PURPOSE: A variable intake system for a vehicle is provided to selectively supply a required amount of air using the negative pressure of an engine of a vehicle. CONSTITUTION: A variable intake system for a vehicle comprises an air duct(110), a main air cleaner(120), an intake pipe(130), a chamber air cleaner(150), a first variable valve, and a second variable valve(152). The air duct has first and second air ducts(112,114). The main air cleaner has a third air duct(122) and an air filter. One end of the intake pipe is coupled to the main air cleaner, and the other end is coupled to an engine throttle body of a vehicle. One side of the chamber air cleaner is connected to the second air duct, and the other side is connected to the intake pipe. The first and second variable valves are installed in a coupled part between the second air duct and the chamber air cleaner and a coupled part between the third air duct and the main air cleaner.
