An intake manifold integrated vacuum solenoid comprising a vacuum solenoid integrated into an intake manifold is provided. The solenoid includes a body and a pair of opposed attachment arms extending from the body. The body further includes an atmosphere port and a vacuum port defined by an annular collar. The collar includes at least one peripheral groove in which a sealing member is fitted. A conically-shaped bore is formed through the collar. The manifold includes an inlet into which the collar of the solenoid is fitted. The manifold further includes arm attachment posts to which the arms of the solenoid are attached. The arrangement for attaching the arms to the posts includes spools with each spool having a peripheral groove formed therein. Each spool is attached to its respective arm attachment post by a mechanical fastener. An end of each of the attachment arms is fitted into its respective spool.
