    摘要： A family of manifolds for a family of engines. A first and second engine respectively have a first and second number of cylinders. The second number is at least one and smaller than the first number. Each manifold has a plenum chamber and an inlet. The first and second manifolds respectively have the first and second number of outlets, each connected to one of a first number of runner passages. The first manifold is manufactured by inserting an outlet insert for forming at least one of the first number of outlets into a first or second mold, forming a first portion thereof using the first mold, forming a second portion thereof using the second mold, and connecting the portions. The second manifold is manufactured by forming a first portion thereof using the first mold, forming a second portion thereof using the second mold, and connecting the portions. The second intake manifold being configured for the second engine and comprising a second number of outlets being fluidly connected to a corresponding one of the first number of intake runner passages and being configured for fluid connection to a corresponding one of the second number of cylinders, at least one of the first number of intake runner passages of the second intake manifold not being fluidly connected to any one of the second number of outlets of the second intake manifold.
