Folks "cold" air needs to be refridgerated air. Once your moving most of the hot engine air is flushed out, it's only stop and go driving where that is a real issue. The VOLUME and flow of that air is the area where a few CIA's excell over stock set ups. Just like the term "ram air" that Vararam likes to throw around. Ram air is produced by turbos and blowers not by a cold air intake. If you can accomplish 3 to 5 rearwheel horsepower and torque on a dyno you have done about the best you can hope for with a CIA. Are you gonna feel that.........NO. In your mind you will and the sound will change somewhat but realistically, no you can't feel that small of a change but you have a nice high flow filter and more volume for the intake and that is always a good thing.

My opinion: modification of intake tube is the only thing the stock intake lacks due to the ribbing.

although it always appears the difference in hp is only a few hp, we don't spend all our time driving around on a dyno roller with no air movement. almost any intake that offers smoother flowing air with less bends as well as do away with the air resonator will be a big improvement. More enhanced with any additional mods and especially more if you can get custom tuning for the better airflow.. In my opinion, it's hard to measure with dyno numbers the true performance of any intake. I can tell by the street manners and how well my truck accelerates from a light that an intake works. I've tried a few, first, a homemade 4" pvc setup from the tb to the stock airbox, drilled holes in the bottom of the stock airbox to allow more airflow. Then I did a smooth mopar clone ebay knockoff with a heat shield. After that I got the Ramhammer (BFI) and the performance improvement was obvious. I then bought a used Vararam to try, it worked so well that it was hard for me to tell the difference between it and the Ramhammer.

Does it really matter what it does? It makes the 5.7 go from mild sounding at WOT to OUT-freakin-STANDING at WOT! I was surprised at how much louder the intake is, especially in the cab...besides it just looks cool!

i think the cai look great, sound great,allows more volume of air to combust but it worries me that the filter can allow bigger particles into ur engine.its the only thing holding me back from putting 1 in.

the filter doesn't let any larger particles in, and if ur particularly worried about that run a pre-filter as well.

I've run some form of Cai for over 185k miles...nothing to worry about...I've run down the track a ton without a filter as well..
