Intake system for vehicle

An intake system of a vehicle, comprising:

• an intake manifold having a plurality of runners for supplying intake gas to a multiple-cylinder engine;
• a surge tank cover coupled to the intake manifold to define a surge tank communicating with the plurality of runners via the intake manifold;
• an intake air inlet formed on the intake manifold as a passage through which intake air flows into the surge tank;
• an intake outlet formed on the intake manifold as a passage through which the intake air sequentially passes through the intake air inlet, the surge tank, and the runner, and is discharged to the engine as the intake gas;
• a gas inlet which is a passage formed on the intake manifold and selectively receives recirculation exhaust gas;
• a gas chamber formed on the intake manifold so that the recirculation exhaust gas flows in through the gas inlet;
• a plurality of gas distribution passages on the intake manifold to communicate with the gas chamber;
• and
• a gas distribution hole on the intake manifold as a passage through which the recirculation exhaust gas sequentially passing through the gas inlet, the gas chamber, and the plurality of gas distribution passages flows into the plurality of the runners, respectively.
