PURPOSE: An intake manifold having advanced PCV gas uniform distributing function is provided to evenly supply the blow-by gas, flowing in a plenum chamber through a PCV nipple, to each intake runner with a fixed amount. CONSTITUTION: An intake manifold having advanced PCV gas uniform distributing function comprises a main body(10), a throttle body(20), a plenum chamber(30), a plurality of intake runners(40) and a flow path bar(50). The throttle body is formed to be connected with one side of the main body and transfers the air mixture to a vaporizer. The plenum chamber comprises an inlet hole for the re-inflow of PCV gas from the combustion chamber and performs a temporally storing function of the air mixture supplied through the throttle body. A plurality of intake runners is formed in streamlined shape to uniformly supply the air mixture of the plenum chamber to a plurality of combustion chambers. The flow path bar guides so that the PCV gas passing the inlet hole to uniformly flow in each intake runner. An inlet hole is formed in one side of the flow path bar to correspond to the inlet hole. A plurality of inlet holes is formed on the other side of the flow path to correspond to each inlet hole.
