i doubt it.
although it's a good concept, you really need to combine it with an intercooler for it to work effectively. As air is a natural insulator simply running it in or around the intake is not going to cool much air. You need something where the air runs through a lot of fins for there to be enough surface area to cool the air sufficiently.
You can use it to combat heat soak in the intake manifold and tubing, but that will be all it will do. Meaning you won't see any real gains just prevented losses.

oh ok i see Thats a good point

i think its a good idea, it sprays cold air into the intake thereby mixing with the hot air coming through the intake, and making cooler air coming into the throttle body
in theory this would cause a true cold air effect, making more power
i wander what kind of gains it has

the lack of any dyno figures posted by CE for this thing pretty much says it all......if there were any noticeable gains you KNOW they'd have a huge dyno sheet up there.
good in theory and good in reality are two different things.....any small gains would be counteracted by the weight of putting that stuff in your car....
also, I don't think it sprays cold air INTO the intake, just around it. Spraying CO2 into the intake would not help performance, since detonation requires oxygen, not carbon dioxide......but even cooling the intake surround seems hardly worth it, since the air is going through there so fast it's not going to have time to do any significant cooling....

Hello my fellow Max owners. I'm the "6th gen guy" who has the CryO2 Intake cooler.
First of all, I agree that the company would benefit by showing some real dyno sheets on their site. It's easy to make claims, but they'd benefit a lot more if they would show proof.
Second, the system really does work. The 4" length of pipe that is used for the intake cooler contains a metal bulb inside that the liquid CO2 passes through. I have it placed just before my MAF sensor which, in my opinion, has the greatest effect. The entire pipe, along with the solenoid and connectors, gets ice cold after using the system. If I were to estimate HP increase (I don't have dyno tests) I would say it's around a 7-8HP gain. Whoever said that the weight of the system would counteract the HP gain is a little off. The entire system, including the tank, weighs around 12lbs. That's with a full tank of CO2. We put subs in our cars weighing 4 times that amount with a box and don't think much about it.
The only problem I'm having is getting a full bottle of LIQUID CO2. Once the liquid is gone you are just blowing gas through the line and it doesn't do a thing, other than making noise as the CO2 vents.
Is it worth the money? Probably not, unless you have forced induction and an intercooler. Then you can vent the CO2 onto the fins for greater cooling. It does help though, and looks pretty sweet.

Greyarea How often do you have to fill up your bottle(what size tank)? How long does it last? How much does it cost to fill up a tank?
Personally i would like to see a direct comparision of C02, N20, and water/alcohol injection.

do you guys understand that if this mod did inject co2 directly into the intake stream then it would actually be effective in lowering intake temperatures by a lot? But it DOES NOT.
Besides, even if it did inject CO2 direcly into the intake charge, CO2 INHIBITS COMBUSTION.
You want real power? spend the equivalent money on a nitrous set up.
