I agree, just get a drop in, the factory intake is almost a cold air intake anyway, not sure how you can make it much better short of maybe putting a hood scoop or something like that, forgot to mention, according to my scangage, the intake temperature is within 1 or 2 degrees of the outside temperature, certainly doesn't get better than that.

This is a scan gage. Not showing intake air temperature in the photo, but it will if you want. Since that temperature is displayed constantly on the instrument panel it's of little interest on the auxillary gage.
Thats a big version of the one I have, but exactly right. My instrument cluster does not display intake temp? You must have an EB or Limited. The scangage displays just about everything the truck monitors, and it plugs into your OBDII port, plug n play just a bout every vehicle since 96, very easy and relatively inexpensive. Mine also reads any engine fault codes and gives me the ability to reset them. Just a gadget...

It generally stays in my car, for gas mileage tracking, but it is not vehicle specific and easily transfers from vehicle to vehicle. You can find them 100 to 150. It monitors fuel rail pressure, throttle position, %load on the engine, and a ton of other parameters in real time. Like I said, just a gadget...certainly not a necessity.
I agree with the factory intake is basically a cold air intake. With my MSD Dashawk monitor, I'm seeing temps at cruising speeds <5°F then the outside temperature display on the dash.
I was a bit disappointed that it is so efficient because that means that an aftermarket KAI won't add any cooler air for improved efficiency.
Shouldn't CAI be called AII. Ambient air intake? Cold air? I guess if we took a ice chest full of ice and routed the air intake through that, it would be a cold air intake.

Most of the newer factory set-ups will draw air from 'outside' the vehicle -- which is to say, it wont be artificially hot air from inside the engine compartment. My Scangage indicates the same as nfntruth said, within a couple of degrees (usually) of the ambient air temp (unless you're at idle or moving slow while 4x4'n - then it'll jump up).
Even aftermarket CAI's will only give you air that is the same temp as ambient air. On a hot day, using the ice trick would probably just confuse the computer and cause you to run really rich and lose power and economy.
