Been looking at all the choices out there for my 2010 GS. Is there any real proof of hp increase from any of the brands out there with no other mods done? It seems that most manufactures do claimes, no good proof! K&N seems to post some of the highest hp increases on the dyno. I would love to be in attendance while they were doing some of these tests! Has any one done a before and after with just an intake change? Looking for independant tests not the manufacture claims, I would love to see responces with several of the brands out there! thanx for any info

I would not look at a new intake. You have a very good one from the factory.
If you have 4 or 5 hundred that's just burning a hole in your pocket....then make sure you actually get a CAI instead of just a different filter.
I have the Killer B with the beehive.

P.S. If you do a 'search' for 'intakes' you can read for a couple of hours on the subject.

Well, since this question has never been asked before I'll help you out. Performance wise, Vararam is best. You have to cut the shroud to do any good with a CAI.

I was looking at the halltech super bee with the beehive, do you feel it has an hp increase and better throttle responce?

Seems like all the "gains" I see are from companies that install the intake then have a tune so I wonder actually how much HP incrase is there with a CAI? I have read some on the subject but the unbiased evidence is hard to find.

In my opinion, no.
I have yet to see any Corvette C6 cold air intake show any significant gains on a chassis dyno, maybe 5-10rwhp at best and even that wasn't repeatable/duplicatable.
If you're only looking for gains on a dyno graph then you might want to save your money.
But some of us are actually seeking gains (or reductions) on a different piece of paper and in that department the Vararam Snake Charmer certainly excels.

Save your money. I've tested the Vararam, K&N and Vortex at the track and got almost no gains compared to my stock one and a cut shroud.
Do a search here on the forum in this section and in C6 General. This topic has been debated TO DEATH.
If you are leaving the factory tune in the car, and not adding any other mods, don't waste your money. Even getting a tune, its hard to tell what HP increase came from the tune, and what came from a CAI.
In the years of the LS1 and even LS2/6 , those intakes were fairly restrictive, so people were seeing decent gains from these intakes, but now with the LS3, 7 and 9 , GM has improved the factory intake quite a bit.
I am not going to say which ones I have used cuz I don't want to start a pizzing match, plus, if you talk down any one vendor product, the moderators will lock this thread.
Trust me, don't waste your money., especially on a stock car with stock tune.

I can't say. I did a lot of mods at the same time as the CAI, along with a tune, soooo. I would recommend just opening up your lower cowl and get some cold air to your present filter. Unless you are planing on a lot more mods....that's all you will need.
I also have the Vette-Air to actually get more cool air to the intake.
I cut a hole in my shroud than sealed an oem filter & housing to the hole I cut and picked up approx. a tenth and a half the next time I took the car to the track. 12.19 @117 mph (A6, full tank, 250 lb. driver) weather conditions were about the same.

Adding CAI can't really do much without increasing flow throughout the engine cycle. It's like adding a larger carb to a restricter plate motor.
Colder air from outside the engine compartment is denser air i.e. more molecules of oxygen in a given space which will make more HP. The rule of thumb if I remember it correctly is 1% more hp for every 10 degree reduction on a n/a engine. So if the outside air is 80 degrees and the under the hood temp is say 130 degrees how much more hp are we talking on a 400+ hp engine?

So in theory you gain 20 HP if the stock tune manages the increase in RAD appropriately.

Sometimes the Vette-Air will give a surge on a stock intake. Joe'sC5 installed a baffle at the exit point of his Vette-Air to divert some of the air from the mouth of the filter. If you do a 'search' you can read and see what he did. You could just cut a 4x12 slot and quit. That would be a good place for cool air to enter, and maybe not cause a problem with the stock filter. There's several different ways to get the cool air to your engine.
I chose to go the Killer B route, which with it's design baffles the air anyway.

I would leave it stock unless you plan doing a cam and headers at a minimum. I bought the Airaid to go with a cam, stall, and headers on my 10' Grand Sport coupe. If I wasn't doing this I would have left the intake alone

I've heard 1 hp for every degree cooler air to the intake. Split the diff and anyway you can get outside air "inside" will help--especially on cool days. Thought I read (on this forum several years ago) about propping the shroud open, rather than cutting it, and hanging a K&N Aircharger down in the (now) outside airflow. Seemed like a good idea, so I did it. Does seem to liven up the engine on my '06, but seat of the pants can be deceptive.

my $.02- if you are leaving it stock, save your money. I have an LS-2 and did notice a difference after installing my Callaway Honker. Felt even better after the Predator tune (tune has been removed now). But honestly, for an unmodified street driven only Vette, I would save my $ if I had to do it over again.
