A simple and reliable connection between an air resonator and a throttle valve body is achieved with a resilient vacuum seal. The vacuum seal is positioned in an outer periphery of a boss on the valve body, and provides an interference fit with the resonator. The seal preferably has a seal lip extending away from the resonator such that a vacuum drawn within the resonator pulls the seal body more tightly against an inner periphery of the bore. Moreover, vibration isolator surfaces are positioned on the seal to dampen vibration between the air resonator and the valve body. The present invention thus provides a simple and secure method of connecting the air resonator to the valve body.
