As far as I can tell. One of the ducts is just there cosmetically and doesn't run anywhere in the first place. The other duct is an air intake for the engine. I'm sure air is still flowing into it, probably just not as efficiently. I think most of the air flows in from the kidney grills area anyways though. I doubt there is that much performance lost.
