Just looking to see if anyone is running A cold air intake on their truck. I al talking about a full intake not just a drop in.

The stock intake is, by definition, a CAI. I have used aftermarket units in the past and will never again waste money on them. Not only do they fail to significantly improve engine performance, they invariably do more harm than good. Oil used in the filter element tends to coat the MAF sensor, while the filter itself can allow a significant amount of dirt to enter the throttle body.
Additionally, the OEM breather has its intake outside the engine bay, while the aftermarket units are inside.

not all aftermarket CAI 's draw air from inside the engine bay and not all CAI's use an oiled filter.. please get your facts srright before you steer somebody wrong

^^^^i agree with tech^^^^^

But all K&N CAIs are. Please read all the post before jumping down somebody's throat.
Fact is, for MOST applications, the K&N kit is a waste of money. I try to never say never, so will stop short of ALL.

I actually have the oiled k&n cai and it does draw some air from the engine bay but it also draws a lot of air from the hole leading to the driver side inner fendewell, which means it's cooler because of the air forced in when the tire is spinning. I would have opted for the Blackhawk series but it was not out at the time I purchased the oiled one.

I am not simply regurgitating some rhetoric I heard/read somewhere. I have had the K&N system on two different vehicles. Being well aware of the shortcomings of the design, I have chosen to not install it on my truck.
However, this is a good opportunity to point out to the OP that while based on my experiences, my post is still only my opinion and my recommendation. While it could be said I am discouraging the use of the K&N ( I am), I don't want the statement that the OEM intake does, in fact, take air in from outside the engine compartment, and does, IMO, function better than the K&N to get lost in the shuffle.
It is a truism that the engines in these trucks are not simple machines. The computers integrate hundreds of thousands of bits of data per second to achieve optimum timing, fuel flow, air intake, and such (optimum being defined by the manufacturer). To change anything without regard to it's potential effect on other systems can at worst cause damage and at best be ineffectual due to compensation by the computer.

Point taken, not trying to bash you bro so sorry if I came off wrong

I have had K&N in the past and will never have another. Oiled filters are garbage in my opinion since they have the potential to leave oil residue on your MAF, which is never a good thing. If the CAI (cold air intake, "cold" being the key word) has a filter that draws air from inside your engine bay, well then it is NOT a CAI. I prefer just a few filters, WIX or if you have the urge for a "performance" filter, buy an AEM (which is what I run). Does my AEM improve performance? Not enough that I really notice, but I did it with the Gotts mod and it does make my exhaust louder, which I prefer. I average 18-19 on my weekly commute on an 07 with 135K, so I can say that I like my set-up.
