Process for producing an intake manifold with several pipes provided with valves and ending at the level of a common plate that defines a contact surface with the cylinder end block. This process includes: Providing a functional unit [shaft (5)/valves (6)], parts (7) to be inserted that form bearings, and a manifold body (1′) or splitter body (1); Installing the functional unit [shaft (5)/valves (6)/parts forming bearings (7)] in end portions (2′) of the pipes (2), and recesses and/or housings for the receiving (8, 9) of the plate (4); Implementing an over-molding at the level of the plate (4), the material connected by over-molding ensuring, the mechanical locking of the components of the completed functional unit in their recesses and/or housings that respectively receive them and that constitute formations that work with or produce the sealing against gases between the end portions and the cylinder head block.
