Default CAI - stupid question, educate me

So I looked under the hood and if I didn't know better I'd say I have a cold air intake. Big filter, walled off from engine, etc. Looks like a CAI but I'm guessing it's not. So what makes a CAI different from what I'm looking at?

Is it the smooth intake tube? Why can't I just replace this one with a smooth tube? Is it more than that _ (pretty sure it is).

You, my friend, have the mopar cai, so you're set. CAI has become the generic term for any intake tube that has higher than stock flow numbers and a larger filter area, even though most of them don't pull cold air.

True CAIs will pull air from outside of the engine compartment, but most just seal off an area and pull from inside the engine bay from behind their 'heat-shield'. The smoothness of the intake tube will make a difference if you're pulling larger quantities of air and need to have a laminar flow into the intake manifold, and most 'CAIs' are smooth enough to not cause any issues.

If you want a truly "cold air" intake, then you'd have to look at a composite tube (prevents heat soak of metal tubes) that pulls air directly from outside the engine bay, and I only know of one manufacturer that eally pulls this off, but it's only for the LX vehicles, not the ram trucks.

R U Kidding me? I have a CAI? I was considering the purchase of a Volant CAI - in part cause I like the looks of the enclosed filter box and the fact that it has a ram tube to truly draw cold air from down around the bumper --- but I'd feel kinda stupid buying a CAI to replace a CAI.... that would make no sense, right?

You would be buying a BETTER cai to replace an OK cai, but it's your choice, not much benefit between the two except the Volant will clean the air better without restricting the flow.

IMHO the Volant is worth it for the PowerCore filter. I tried and tried to fit it into the stock air box and just couldn't do it so I bought the Volant. Better airflow, better filtration and a 100k mile warranty on the filter. Nice mean sound @ WOT too!

Glad someone does Ramathorne - I hate it - the black plastic ribbed tube is FUGLY if you ask me. I'm hoping I can swap it with a K&N tube or first choice - one of LGIs carbon fiber tubes!
