I wouldn't have expected so many questions to get asked in the DIY thread, sorry guys! As was answered, there is NO problem with the "hungry mouth," and it's been on all of our airboxes. We made a conscious decision not to seal the gap because the box itself is not sealed, and doesn't need to be sealed. This helps promote airflow by not having stagnant sections of air, and also allows for a release of water should that ever get in. You'll notice that the stock airbox is not sealed either. However as far as performance goes, I don't think sealing it makes a difference at all, as the amount of cold air coming in form the snorkel is so substantially greater than the amount of air that would be slipping through the cracks, and since air will follow the path of least resistance this will always hold true.

So you can seal it up if you'd like, but I think any potential for gains aren't really there, especially because it is already making very healthy gains as it is.
