CAI or Stock Air Box

Coming from my standpoint, I just dropped a Spectre Air Filter a couple weeks ago. Got it from autozone for $25. Took it on a test drive and wow. So much more responsive, better throttle response, and maybe 1mpg better. Not saying I'm an expert or anything, but after driving my car bone stock for 3 years then dropping in the new filter, yeah, theres a noticeable difference. Also, if I want to floor it, the RPM's go higher and the car keeps pulling. There's also a nice deep grumble inside of the car. As for the outside, I had my brother floor it and drive past me, sounds like I do have a bit of an exhaust. Slightly.

Yes if your "CAI" is sucking in hot air the stock air box would be better.

x2, there is a another piece of your stock intake, its in the wheel well, you should remove so the CAI can sit lower and have access to cooler air. Wait until the fall/winter time

That's how mine is. How would you go about installing on the goes into the fender?

I was thinking of making my own, or was looking at the Volant CAI, but if you look around you can find some, there is a thread here how to make your own.

I am the guy who switched back to the stock intake and noticed better throttle response. The CAI was an Airaid w/the air dam, so it was not pulling too much heat from the engine. I also have a Magna Flow catback exhaust. Now that I have had the stock one back on for a few days my observation on "my car" is that the stock intake definitely has better throttle response, and also seems to pull more consitantly through the gear changes. The only real difference with the CAI was it would rev higher and louder before shifting, and the sound was deeper when you first started the car. I also think that the stock intake is a cold air intake, when you think about where it is pulling air from. The only real difference is the actual filter. The CAI cone filter does have more surface area to pull in more air, but giving the fact that it pulls air in from the top as well, I would guess it pulls more warm air from the engine than the stock box....look at the Volant system which is also closed.
The conclusion for me is that the after market CAI might net a small increase in peak HP, but at a lose in the low end. I also think with the computers cars have today, you would probably have to also get a good tuner to really maximize the gains enough to feel them.
Just my two cents....hope this helps.

I completely agree, I have noticed a few time that the metal mesh on my cone filter is hot to the touch, after a day of driving, so my opinion is if the filter gets that hot, the air it's sucking in is even hotter, so I'm looking at replaing it, down the road (job issues right now don't have money for anything) but that will give me time to do some more research on the filters.

Never thought of that...I also remember taking the filter off to clean it and it being hot as hell. Never dawned on me that it was odd for a "cold air intake" to be so hot. Watch...now they will start making "HAI" because they found that it expands the fuel particles allowing it to atomize better!

Short ram CAI wont really give you anything more than the stock. You might get a couple of extra horsepower, and on other days you might have a little less depending on the environment. You will probably gain one or two mpgs and you get a cool wooshing sound...that's it.
Short ram intakes really aren't good by themselves for performance increase. And never listen to manufacturer's gains, Big Bully says they'll give you like 11 or 12 increased horsepower is a crock, no way will you ever get consistent results like that with a short ram. Manufacturer's can legally tweak how they do their dyno testings to get the results they're looking for. In real world driving you'll have a couple of horsepower and that's about it.

Yeah like dyno the car with the hood open and a fan blowing cool air over the engine bay!!!

I thought a CAI actually decreased gas mileage due to the fact that the computer sees more air being taken in and therefore uses more fuel to maintain a consistant fuel/air ratio.

if you guys havent considered it yet check out the bullet CAI from stack performance. it mounts the air filter down in the fender area like the "true CAIs"
I have no personal experience with it but after shopping around and doin research this is the one i will be trying in the near future

I just ordered a Green Filter for my stock box, figured I'd try a $50 filter before I dove into buying a $350 CAI. It was recommended to me by Brian @BND.

Hi Ddaddy! your air funnel or smooth intake tube looks great!! That would give some more HPs, for sure, because don't create the so-called turbulence. Where did you bought it? Give us the info, please!! Also, the stock air box from the SRT8 is the same of the Daytonas and R&Ts, but different from the R/Ts and SXTs. That could make a difference in air intake, right?
Stock Air Box with a high-flow drop-in air filter and a custom CAI style smooth intake tube to reduce turbulence...FTW! :bigthumb:
