The NACA duct is silent. The intake roar through my carbs and the bare firewall however, are not. Still, I can shut the car off at 120kph and I hear no difference between duct wide open or covered.

Winter mode has three covers (complete, partial and minor), summer mode is wide open (but I don't have a photo handy)
