CD2 is a great product but kinda hard to find. I had to get mine through a Corvette club. At one time I did own one so it was kinda like a "white lie" . Great stuff. Racehorse like your CAI, I have the same on mine, I need to post pics in my gallery. I see you were bugged by that hole in the engine cover (passenger side) as well. I found a plastic (PVC) pipe cap that fit in that hole nicely and looks like it belongs there, quite a few people are using the center cap idea, I wanted something a little more generic. Pics to follow.
