ABSTRACT:
An engine air intake system, which may include a supercharger or other air-handling device, includes a resilient coupling connecting an air intake connector, such as a throttle body, and an air inlet duct. The resilient coupling includes a bellows convolution for allowing limited motion between connected components. The coupling is molded with tuning volumes and connecting passages within the convolution with open sides to allow removal from the mold die. An associated connector closes the chambers upon assembly and forms noise reduction tuning for high frequency air pressure waves.
