intake modification idea
i currently have a dual cone intake. i was trying to see how i can get more air-flow to get to it. couple of ideas were: 1) cut open the fog light surround. they do sell pre-cut ones, but if all i gotta do is cut a hole, i can do it myself and save $50-70. .. 2) after i cut the hole in the fog light area, attach a hose (like a heater hose- flexible material) and lead it towards my intake cone.. .. i dont think i really want to do either of those, so i thought of a third idea; 3) cut a hole/slits where my intake sits on the radiator shroud so air can directly hit the filters from beneath
this is what my intake looks like
i did a quick google search and i came up with some pictures of people doing something similar with their Haltech Stinger.. i dont know if this is really how Haltech installs them, but it looks like a good idea. only difference is that i dont want my filters to go through the shroud outside the engine compartment, rather i just want to cut a hole/slits where the actual filter lays against the plastic

Do yourself a favor and sell that twin flow and pick up a Vararam,Haltech or Vortex. I had the exact same intake on my 1st C5 back in 01 and cause's turbulence at the MAF and doesn't gain much. You would be better off just taking one of filters and attaching it to the end of the maf.
Good luck

Even the flip tie method breaths better than the dual cones. There was a guy about a year ago that did what you're talking about. Didn't work all that well from what I remember.. but it did look

I want to do a Chuck Cow tune while it's still on sale for $199 (plus gotta get a $50 low temp tstat) so I cant afford a Vararam and a tune.. but maybe I will put one cone @ the MAF. But im wondering where I would attach the little black hose to if I do that (the one that used to attach to the driver's side on the stock air box.. currently its attached a hole on the dual cone)

You can do a mail order tune but I just think it's kind of a waste if your only doing bolt ons. Also if you do a tune at CMS he will give you a touch up as you upgrade more parts. Good luck on your upgrades. I kinda wish I was still new to corvettes it was a good amount of fun swapping out parts with trial and error. Now I am maxed out on motor side unless I blow it up

Pick up a thermostat at azone for $13.00 and do a Dyno tune at CMS. Give him a call I don't think it will be ton's more for a basic tune with bolt on's. Take the twin flow off sell if for about $90.00 and pick up a Donaldson or Vortex for about $100.00 -$125.00 used or just buy a K&N that slips onto your MAF.

how much is the CMS tune
i know a tune for bolt ons might not be logical, but i have an automatic, in which you see a helluva difference apparently. at least thats what Chuck says and what his customers who have gotten it say. Now if you had a 6MT, that would be a different story, not too much gain there.. dont know why either.
btw, i remember seeing a k&n that was nice and big/long for $99 brand new.. i forgot which thread it was in and the item #.. any ideas? goes right on the MAF
edit: here i found some, but a little over $99..

im assuming all those fit right on the MAF? also, is the first one the best? seems like it has the greatest surface area.

Keep it cool!
The least expensive way to transform what you have into more of a cold air system would be to core holes in the fog light panels. You could then install Z06 screens so even if your holes aren't perfect, no one will know.
My lower radiator cover modification is better suited for Halltech and Blackwing intakes, as their filters are far narrower than the twin cone profile.
Either way, your engine will benefit by not having to "dial back" power when the engine bay heats up. You can preserve 10 RWHP just by keeping the intake air cool.

Do a search I have had a couple of the twin flow setups since the systems date back to 1999 and the car always felt better and had no stupid engine codes when I dumped the filter. If it works for you then great

you will need to prove that you had 16hp gain from opening up your compartment for a duel cone....i do not believe that gain was achieved...
