I'm running the stock intake and was wanting something extra - to improve mileage (if possible) and hear the turbo more. The truck is about to turn 10k. Would I be better off with a drop in filter or a whole new intake? And with the new intake a wet or dry one? I had a K&N air intake system on my 01 GM gasser - but this rig is a whole nother animal. Thanks for the help guys.

I suspect the prevailing opinion will be a whole new CAI with a dry cone filter that is well maintained. Many of our sponsors sell CAI systems. Just post in the Request a Price Quote Forum...

The turbo charged engine has much more of an appetite for air than a naturally aspirated gas engine. You can run oiled filters, but you have to be very meticulous about the maintenance on them. Over oiling can lead to problems more quickly than on a naturally aspirated engine. I don't specifically know on your turbo, but for example, my Aurora turbo is rated at 1350 CFM. Lot of air moving through there.

i personally like a aftermarket cai with a dry filter, one that doesnt just pull air thru a fender opening. im running a aem kit but adding an amsoil nanofiber at cleaning time

Agree. With the turbo heating the charge air as much as 10 degrees for each pound of boost, volume is more important than temperature.

Dude with where I live and drive a weekly route I am not so much on the re-usable filter systems because of all the sand and dirt in the air most of the time. So what I have chose to do, has been pull the air baffle out of the intake tube just above the VGT, and then just use the later model 5.9 air filter so that once its dirty I can simply throw it away and replace that with new...

Now this works well for me and I like being able to trash the old filter much better than trying to wash all the fine sand and dirt out to re-use like the others. Now with where you live it may not be so dirty there and you can use the aftermarket CAI systems. What I do with the above setup is a lot cheaper but will not flow the air of some of the better CAI systems. There is a host of these to choose from also, that may be your bigger challenge is choosing one LOL...

I have read good things on the AFE Mega Cannon (CAI). I have been told by many that there is no real comparison (as far as CFM ability). AND, I am planning on running one of these when I do my other mods.

I also hear good things about the S&B (CAI), AEM (CAI), and Tru-Flo: XDi (CAI).

I hear alot of guys on here running stock boxes with MIA intake baffles and K&N 5.9L filters... I am not sure on results (turbo noise level, and power/MPG increase).

But I feel that my money would be better spent going towards a complete CAI, and not just a drop-in filter setup!

And, If you are planning on heavily mod-ing your truck with performance parts...I would DEF go with a complete CAI, and NOT a drop-in filter!!! You will cook your turbo, because you will NEVER be able to flow enough air for the truck to properly run!

It's up to you?

But I would go ahead and spend the money on a complete CAI!

The turbo is only capably of taking in SO-much air...

...and when your turbo DOES try to take in that much...don't you want your CAI to allow adequate-flow + some, to your turbo! You don't want it to strain to get air, do you? That's what decreases fuel-mileage and power!!!

That's my theory! I want my CAI to be capable of flowing ANY amount of air (w/o strain), that my turbo needs, no matter what!!!

I am running an afe pro guard 7 that is oiled on my 6.7 and no problems what so ever....but as stated over oiling would play havoc with your map sensor....but that is easily cleaned as well....not much improvement on mpg with these engines by doing that though....

Ok. Looks like a CAI is the way to go. I'll probably pick up a dry filter so I don't have any extra maintainance on the ole goat. Which CAI do ya'll prefer? Price isn't a big deal - I just want the one that works best.

try this. Dodge Diesel - Diesel Truck Resource - Cummins - Home search "willys whistler"
if you want the whistle, this is it. i ordered it last week, should be installed soon. good responses for those who have it. i spent 180 bones w/shipping for a stage two setup! vs 3-400 for the others.
