Why is an aftermarket CAI better than stock
Just bought an 04 5.7L. My plans include superchips and exhaust, but I'm a little puzzled about the whole CAI thing. Probably because I'm a clueless Dodge newbie.:LOL: Sorry about that.

My question is, how is a CAI better than stock? It looks to me like the stock intake already is a CAI. What's the advantage of getting a CAI set-up over, say, just getting a K&N drop-in?

Sorry if this has been answered before, I wasn't successful in searching for this particular question.

Most CAI's will handle more air.

More air in + more air out = More Power

A good CAI has access to cold air (CA part of CAI) not from the engine compartment, but air coming into the engine compartment. They also have a high flow filter whereas the stock filters are somewhat restrictive. Lastly, the tube connecting the filter box to the throttle body (TB) will be smooth versus the stock tube which is not smooth. The smooth tube allows for a good solid even flow of air. The ribbed tube (stock) disrupts the airflow.

From what I can gather the stock intake gets air from inside the fender. Where does an aftermarket CAI get air from?

The stock CAI does get its air from the fender which is great. It only lacks in the filter and tube area.

Many of the aftermarket CAI's are not true CAI's as they get their air from inside the hot engine compartment.

You may find this discussion on CAI's useful

Yea I'm a little nervous about installing an intake on my truck. Had one on my old car and when the summer came, I lost performance with it. Was a short ram intake with a heatshield, basically the same thing they offer for the ram hemi

Another option is to do a drop in K & N filter in the stock box & cut out the 4" flex ribbed section (about 9" long) & replace it with a smooth 4" plastic tube.

I prefer to drop in a K&N I experimented with my Lightning on CAI...and found that the factory box with a K&N was probably more efficient than the C&L Elbow and K&N cone. Try the drop in filter first you will be surprised.
