Performance DiscussionThis section contains discussions about performance enhancing modifications with sub-sections for both the regular Dodge Caliber and Dodge Caliber SRT4.
Hey, just wondering about the Mopar CAI. I'm from Ontario, Canada and wondering about the availability. I asked my dealer and he said there are no "performance" parts for the 2007 Caliber yet.
I'm just looking for the cost and such. Would I be better off just waiting until AEM or Reactive come out with one?
CAIs have earned a bad reputation because of companies like Ractive who design it to just look pretty.
Time for a lesson!
These formulas are theoretical, real life factors may raise or lower the numbers you get from these formulas. So first lets find out how much of a filter our engines need.
CFM= Cubic Inches x given RPM / 3456
It's 122 cubic inches, correct? 211.8 CFM at 6,000 RPM, 70.6 CFM at 2,000 RPM.
So now we need to find out the effective area of a filter and what CFM said filter will give us with a cotton gauss media:
Effective Filter Area = (Length - .75) x Height x ?
Cotton Gauss Flow = 6.03 CFM per Sq/In
A 6" long tapered conical cotton gauss filter with a 3" flange would be more than sufficient breathing for the 2.0L. There is such a thing as too much filter media.
However, the amount of air you are getting is not the only benefit of a CAI.
Colder air is more dense than hot air. By pulling air from the fender or further forward in the engine bay (where fresher, cooler air is), you can "pack" more air into the combustion chamber.
This denser air at say 70 degrees will expand much more than air that started around 120 degrees. The air is heated the same amount when used in combustion, so you essentially have more air in the combustion.
Now a tune/computer can dictate whether this will result in performance or increased gas mileage. If you can spray less fuel per cycle, you will save gas in the long run.

Hey everyone, if you want a CAI do yourself a favor and go to home depot. Yes that right, Home Depot, the big orange do it yourself store. Figure out some bends, and pipe length to get a filter in a good cold air stream, Buy yourself some PVC pipe, and some elbows, get yourself a chep-o filter from EBay, BAM there is your CAI....
gsx rated98, you obviously have no clue to the long term effects of underhood temps on PVC. PVC will deform and fail.
Seeing as to how i use it in a turbo charged motor, im very well the aplication of PVC, and the effects of what can happen to plastic. And if routed properly it will work just fine.
As stated above, you can use dryer hose as well, but does create turbulance issues because its not smooth.

lol thats a great idea, except I wouldn't be able to open my hood in front of anyone without feelin like a nut. Thats like using a coat hanger for an antenna LOL!
