An integrated intake manifold-fuel rail construction with a separately molded trough-shaped fuel rail component friction welded to a runner spanning mounting plate molded as a part of the manifold. A filter is installed within the fuel rail component to intercept particles generated by the friction welding process to prevent their entry into the fuel injectors, each having one end installed in one of a series of sockets formed in the fuel rail component.
