Z06 air box mod complete...
First I must point out that a stock 97 airbox has ABSOLUTELY no opening in the front what-so-ever! I found that to be odd as I have seen pix from other year C5's having ever so small of an opening...? 
Any way, after removing the lid and plopping in my K&N filter along with aligning the box I was finished in 30 minutes (this included cleaning the front of the radiator shroud) well my first impressions are that the throttle response is noticable...and I can hear the engine taking a deep breath now...I have yet to get on it- but I assume even though I may not get massive amounts of HP with this mod...I notice her breating A LOT better now...
Just thought I'd pass on my experience...finding no opening in the stock lid was still something I did not expect!

Tim, My '04 non Z06 had a lid that looked like the small opening Z06. Chia, I popped the entire box out when I put the new Z06 lid on.

I just got back from a drive- I can really tell a major improvement in throttle response...and I had a slight rough idle...it seems to be gone now??? there is no hesitation that I felt before like the car was sucking against a solid plastic shroud...why they didn't do this from the git go I have no idea! well worth the time and $$ spent on this mod!

I'll do some checking as to when that was supposed to have taken place.

This might be a dumb question but If the air box is sealed where does air come in from?

Not dumb at all!
What everyone forgets is that there is about 10 sq. in. of intake opening Underneath, that is, on the Bottom side of the air box.
The little openings on the top side are Not alll there is!
