Why the change from OILED to DRY?
GM Trucks have finicky MAF sensors. If you over oil the filter or just over a long time with the normal amount of oil, oil can accumulate on the MAF sensor and gum it up so it doesn't read properly. A dry filter uses no oil so this isn't an issue, plus cleaning is that much easier.

There are several considerations when looking for a good CAI system. First is the engine, second is temperature, third is the tune and finally the cleanliness of the system. There are several methods testing any changes--drag strip times, dyno tune or a scan log. Sound and seat of the pants are very misleading performance indicators. For a mostly stock system--stock exhaust manifold, intake, etc the addition of a smooth intake has no advantage unless you modify the tune. GM used an adaptive strategy in the system design (firmware) for the air make-up chamber, the flex tube, maf, etc and any change in the system will not necessarily mean better performance. The reason GM used the plastic intake is not because of weight but HEAT. The performance potential of a CAI is made by lowering the temperature of the incoming air. This equates to a denser mix of air to fuel and properly tuned this means more HP. Just adding the Volant doesn't guarantee performance, but is a first step.

Years ago I was a big fan of K&N type filters, today I am like other have said--a good quality dry filter is the most problem free.

Personally i like the Air raid intake, if you buy the one for efans the bend/curve at the TB is very gradual compared to all other intakes... I really don't like a hard 90* angle right at the TB.... here are some pics (one with a ls6 intake and others are stock truck intake)

I believe the K&N on my CURRENT Truck has an Oiled Filter, and about 2 months ago my SES light came on. Ummmmm yeah I been meaning to ask, how often should I be cleaning my Filter out? It see's Harsh Conditions everyday whether it be by me, weather, or the road. I just passed 65,000 & its been on since 15,000.......that's too long huh?

It will be a RC & the Engine will either be a 5.3 or possibly swapped out for a 6.0.
Well I'm in Houston where its HOT & being 5 mins from the coastline it is very HUMID! And I am going FI, Cam, LT's, Dual w/ X or ORY?, & MagnaFlows maybe with some Electronic Cutouts. For the transmission a Shift Kit w/ Servo & a Stall.........& then finish it all off with a WHEATLY TUNE I figure starting with this setup will keep me HAPPY for a couple years since the most I ever had was a Half *** Exhaust, a useless Handheld Programmer, & the K&N CAI, PLUS the weight of a CC.

I think your right, I believe he just used the Volant Box, had it Carbon Fiber'd, & threw a different filter in. Can't remember which filter?

if your going FI then why not spend the money of the CAI and wait until you get the Turbo/ S/C. Because when you go FI you will have to lose the CAI.

As with the long tubes you would have to lose those as well if you go turbo, unless you go with a rear mount setup, but i would recommend a front mount.

That's why they flow much better with the plastic intake tube from what I understand.

Anyways back on topic I went to install it & only 2 of the 4 bolts on the TB come out, the other 2 are bolts welded there with nuts keeping the TB on & they don't reach all the way through the AFE TB. Soooo, I couldn't very well install the 4 new bolts that came with the kit. Like a fool I tried it any how with only 2. It just gave me the SES light, I could feel the power loss, & it didn't sound right. ...
The Volant tube or Airaid that Corey posted look best IMO. I feel the sealed box style is best. SES may've been attributed to only havin a few bolts in, & MAF wasn't seated, letting air leaks past. Someone w/. more experience may explain better or tell me I'm wrong, but it's what I believe.

I'm not sayin to not worry about a CAI, just choose carefully, cause u my not be able to use system or only part of it.

Ya, that.

Is that air make-up chamber that thing that looks like a plastic ball sack hanging there. If so, aesthetically, I just don't like it. It lacks how clean just a tube looks. If the weight thing is my comment from earlier, I know GM used it for heat issue not weight. I just don't wanna keep adding wtg. to my truck. I know of an awesome lookin CAI, but it was of steel.
