what is the best, I currently have a MAC but I read how any hot air from under hood is not a good thing.

I'm sure you'll hear many opinions on this subject, but I have the AEM Brute force 98mm and I like it mostly due to its simplicity of design. The Chickenears cool aid and the PSP fast air (if you can find it) are nice pieces too. I have heard though, from others that those snorkel tubes running down to the lower valance(sp?) pick up alot of sand and require cleaning of the filter more often.

Honestly, if you want to lower your IAT2 temps, invest in a cooler box or killer chiller rather than worry about a CAI, all of them are better than stock. JMO

I just read that "sucking" hot air from under hood is not a good thing, seems like the factory box is better than the CAI kits, most suck hot engine air. Not from the outside as the factory setup is.

DolSVT00

Thats why most CAI kits come with a heat shield, I assume your's did not?

BTW there's some great info on the subject here cold air kits

Yes it has a heat sheild, but the factory box is sealed completely from any hot air intrusion, and I just read that the stock airbox is good for up to 700 hp with no problems of restriction in any way. Yes I seen that article, so why even bother with a CAI kit, just put a k and n in the stock box and go. Until you reach 700 hp it doesnt do squat.

I don't know where you got that info from, But I guess ok? I do know this, many people cut holes in the bottom of the stock air box and run a pick up tube and it seem's to add HP from what I have read.

I have also read that if you open the hole in the fender well to the actual size of the rubber pick up boot on the stock air box it will add HP.

Those articles alone prove the stock box's inefficent design and convinced me to buy a CAI. I have also done those mods but they create a new problem, when you add a pulley combined with the restriction of the stock tube you increase Maf counts and increase the chance of the stock maf pegging (I have datalog's to prove this)

After adding a larger diameter tube VIA CAI it actually decreased Maf counts and IAT2's at WOT.

so sucking hot air is better? I mean you might gain with the MAC but then it loses because it is sucking HOT air in, it seems like whatever you gain you lose. Thought of making a box to enclose the mac heat sheild and then route a tube, it just seems stupid to have the K and N in the engine compartment.

just trying to figure out if the MAC on the truck is worth keeping or ditch it and return to stock, I guess the MAC is better then.

Hot air(so to speak) is better than NO AIR.... Stick with the MAC for now bro.

I got the MAC too, seems to get the air in there ok.
I spent a considerable amount of time this year data logging the effects of IAT1 and 2 temps with 2 different aftermarket filter kits and the stock airbox. The results were quite interesting. The stock air box kept things cooler but not as much as one would think. The MAC and LFP kit were the two aftermarket setups I tested. None of this was too scientific more just fact finding. Here is what I found:

Above 25mph all three provided same IAT1 temps after a few minutes of travel at that speed.

Stopped and idling for prolonged periods of time, the two aftermarket kits raised the IAT1 temps quicker than the stock airbox but only like 5-6 degrees difference at the most. After you get the truck moving at 25 mph for a couple minutes they all read the same again.

Dale Robertson mentioned that some playing with the plastic cover over the top of the radiator may make for better airflow into the open filter area.

The stock airbox even with a kn panel in there is still subject to flow restriction based on the inlet side of the box, not so much the filter, probably why so many has had good results drilling holes in the box.

The IAT results were so negligible, I wouldnt think twice about removing the stock air box in favor of more flow potential.

I have a volant CAI that I modded to add a scoop like JLPs.

sounds good, that is what I needed some #'s showing something, the MAC will stay.

so what is the best? The MAC??????
