Cold Air Intake ??

Hello, I'm a newbie. I searched the forum about cold air intakes, I did not find what I was looking for.
What concerns do I need to address about dust filtration and moisture?
I was considering using a dry filter (EX AEM Dryflow Conical style) with a prefilter.
I have a 2000 TJ 2.5L MFI with an automatic transmission, the engine does not seem to get the necessary air at ~3000rpm (60-65mph)it really starts to run rich. Tried complete tune up, new O2 sensor(bad heater), tested MAF & MAP OK, Araid Throttle Body Spacer.
I am trying to get the best out of the vehicle on and off road. Next thought is a Cold Air Intake?? Any Suggestions, Thanks

You have no idea the debate you just unleashed... go pick up the latest copy off JP magazine... they ran a test on just about every CAI there is right now, granted it was on the 4.0L so I don't know how well it transfers to the 2.5L but should give you an idea anyway... after the debates on here I have decided to at least wait on getting a CAI, but that is just me... you will get tons of opinions though trust me.

A true CAI sucks air directly from outside the engine bay. Kits like the K&N FIPK, AirRaid and AEM Brute Force aren't really a CAI, just a item that allows you to run a large filter that's seperated from the engine bay by a divider, but it still sucks engine bay temperature air.

not gonna happen, dont you think that the jeep engineers would have put a CAI on the TJ if they thought it would make the jeep perform better. all the CAI does for the TJ is add a different shaped filter with a tube on it

the only really good reason i have found to run a CAI is because you need one if your want flat fenders because the stock box wont mount on the new fenders besides that i would save my money, the other people that posted make very good points also

OK, I believe I got the point Loud and Clear!
I always thought more air was better, I need to stop thinking and go 4 wheel'n... that's really why I purchased the vehicle.
Thanks again for all your input.

Well in essence they did with the cross tube/resonator, it just seems they stopped short with that small dia. snorkle intake on the airbox.

amd that little snorkel is there keeping in mind that the vehicle might be offroading including water passes. you add a CAI and it will be alot easier to be sucking in all that water

the only true CAI is a snorkel. anything else still suck hot air from under the hood, therefor they aren't a CAI.
