As long as you zoodad your core support you'll have plenty of flow through the AIS. Without the zoodad there's a restriction, but it's not the filter, it's the snorkle butting up against the core support.
The snorkle on the AIS is slightly longer than the stock airbox and virtually seals itself against the back of the core support. Just be careful if you get caught towing heavy in a bad snowstorm, you could end up with a big block of blue ice in your filter housing (the filter will plug up with snow) I used to throw a small piece of cardboard over my zoodad hole when I was towing in heavy snowstorms (it's only a problem if you're towing heavy enough to be deep into the throttle for long periods in white-out conditions)
