I agree that this is the next restriction, but with two feeds, I doubt these are any more restrictive than say the MAF.

I am going to put it on a Dyno and see if I gained anything at all. This will be interesting since that is the only performance mod I have done so far. I will keep you all posted!

That picture is old and shows my car the month I bought it. There are lots of changes under there including a cover made from the remains of a black plastic box much like the lingenfelter one. I also have nitrous lines, the fast intake manifold, and some painted mounts like the alternator one. I was just messing around in posting that as a joke that it looked similar and not to spread the word of my air cleaners.

Just want to say " Thank's "......
To Dave, for giving me the motivation to do this ! I took my time, and by using a heat gun to allow the air bridge to be " stretched ", was able to get my filters to lay down a little flatter into the shroud area. I did this mod in conjunction with installing a set of American Racing L/T's & Cat. Delete, and along with the actual cold air coming into the engine, it appears that my operating coolant temp. is running considerably cooler. With A/C on, and cruise set at 78, ambient outside temp at approx. 95, my car stayed rock steady at 196 deg. sometimes running cooler, down to 192 deg. according to the DIC, but coolant temp. never hotter than 198 deg. and this is with stock T-Stat, as I have not gotten around to buying and Installing a 180 deg. thermostat, which is what my tuner recomends.
I took the car to my tuner after all this was done, however, due to a difficulty in tuning another vehicle, we were unable to actually get my car on his dyno. He did however, hook his laptop up to my car & check the fuel trims, and they were spot-on, showing zero's ! Which meant it was not running too rich, or lean.

C-6 cold air mod
Like I Said in my follow up, I already had gauze filters in the car.
Here are some shots. I'll clean up my cuts, and build an aluminum shroud to seal off the outer edges. And/or, I'm thinking or trimming the area where the outer parts bolt to the primary, therefore narrowing the entire assembly slightly.
Already, it's working well, and I think with a little work, it will be great. I'm running the long course at VIR next month, and if there are any problems, that is where they would happen (nothing will).
Thanks!

David, really interested in your mod but I couldn't open your pictures could be my computer, if you get a chance or even want would you send email to corvette1992@sbclobal.net, or on CF
But the 2005 intake itself has proven to be a restriction once you start modding, so unless you are keeping the car stock, a proper CAI is a better move.
Frankly, this is so old, that since this post people have figured out that the "toggle bolt free CAI mod" is easier, no cutting, and gives the same effect. I'd recommend the toggle bolt mod...search for it.

I just pushed back the shroud on my '13 and put a piece of threaded rod to hold it open about 4 inches. There were holes in the metal piece that the shroud attached to, so it worked out ok putting the base of the rod in one of them. Could not get the pins out that held the shroud, so just basically tore the shroud loose. Much easier on my '06 taking the pins out, but I needed to put a K&N Aircharger in because the stock filters sucked. No need to replace the new filter, as they copied the K&N and others for stock, so saved $400. No question the outside air gives a ram air effect and will add considerable hp at speed as opposed to the closed box the shroud formed. Still plenty of flow to the condenser/radiator from the air dams. It was cool yesterday, but I noticed the coolant temp was running from 187 to 192 on the highway. Generally, it runs 190-192. Don't know if had anything to do with it, but the kick that comes on just before 5000rpm hit at a lower speed. Total cost: $1.04 and two skinned knuckles.

I did it last night then drove about 50 miles to check it out. First impression is no SOTP difference but i did stop and feel the intake and it was cold. Not cool, but COLD. Everything from the filters to the manifold was cold. This has got to improve performance but not enough that I could sense it. The filters are high enough that I'm not worried about water. In fact they are about the same height as stock just upside down. My only complaint is my workmanship. I am not skillfull enough to have done this well. The shroud is pretty butched up-not something I'm proud of but it was difficult to cut in place.
I did a whole bunch of intake mod'ing and custom tune experimentation, 350 +, on ZX-14, blown 14 and M109's, and once an intake is modded for cooler air, particularly if it is a notable change in volume, less so with just a temp change, a tune was critical.
