Resonance will be of no concern - but it does look as thou some CFD analysis was undertaken as the box funnels the air to the filter in a unique way. Resonance is important in the intake pipe (after the filter), and is probably why the stock intake piping is left well alone... honda engineers dont spend 100's of hours of design in this area for nothing
