Abstract
An engine intake air tuning assembly may include a housing assembly and an air flow control member. The housing assembly may include an air inlet, an air outlet, and a body portion extending therebetween. The body portion may define an air flow passage and a tuning chamber. The air flow passage may provide fluid communication between the air inlet and outlet. The air flow control member may be located within the body portion and may be displaced between first and second positions relative to the air flow passage. The air flow control member may provide a first communication path from the air flow passage to the tuning chamber when in the first position and a second communication path from the air flow passage to the tuning chamber when in the second position. The second communication path may define a greater number of openings than the first communication path.
