In addition, the intake pipe body 1 is stably connected and fixed to the intake pipe body 1 through the interaction of the internal thread 15 and the external thread 21 on the intake branch pipe 2. Since the intake branch pipe 2 is made of silicone, it has good plasticity. The length of the intake branch pipe 2 can be extended or a corrugated pipe can be set on the intake branch pipe 2. The overall length of the intake pipe can be adjusted according to the needs of vehicle intake, and the shape of the intake branch pipe 2 can also be adjusted to meet various intake requirements.

The intake manifold 2 is fixedly connected to other intake components through the fixing member 5. The threaded connection between the fixing member 5 and the intake manifold 2 allows the fixing member 5 to guide the fixed position of the intake manifold 2, thereby adapting the fixed position of the intake manifold 2. The sealing ring 51 covering the connection between the fixing member 5 and the intake manifold 2 can effectively improve the sealing performance of the connection between the fixing member 5 and the intake manifold 2, preventing air from leaking out from gaps during the intake process. At the same time, the fixing member 5 can improve the stability of the connection with other intake components through the multiple annular fixing grooves 52, preventing the fixing member 5 from falling off.

[0036] The mounting member 5 also has a mounting ear 53 on its side, which has a mounting groove 54 and a positioning step 55 at its bottom.
