The utility model provides an intake manifold belongs to automobile parts technical field. It solved current gas blowby enter into mix behind the intake manifold evenly lead to the knockings of cylinder single cylinder inadequately, unusual scheduling problem burns. This intake manifold is including the inside body that has the cavity, has main intake hole and a plurality of on the body and is used for the gas outlet that links to each other with the cylinder, and the position department of being close to a gas outlet on the lateral wall of body opens has the pressure stabilizing cavity, is equipped with a plurality of venthole in the pressure stabilizing cavity, and the venthole sets up with a gas outlet one -to -one, and every venthole all is linked together with the gas outlet of propping up that corresponds, still has the connecting pipe on the lateral wall of body, and connecting pipe and pressure stabilizing cavity are linked together. This intake manifold has the even advantageof the gas blowby of messenger distribution.
