Intake temps CAI vs. factory

I took a drive this morning and wanted to know what kind of difference my cold air intake made vs. not having one was. My Titan with a Volant (non ram-air) was pulling in constantly 40-42 degress. Then I hopped in my buddies Chevy 6.0 with the Edge programmer and his was pulling in 57-60 degrees. He has a stock air box on his truck. The temperature was 35 degrees outside. I was pretty impressed to actually see the difference in a CAI vs. factory air box. Yeah I know we had two totally different vehicles, but I still think it would be extremely close either way.

Considering our stock box is already setup like a CAI I would think that the change would be nominal. Probably less than 10*. What is bigger I think is air flow volume.

His airbox is in the same position as ours. Sorry but my findings tell me otherwise.
It was just a hypothisis. Someone should tape a small digital thermometer inside the airbox as it is stock and then after a CAI and see what the temps are.

The other thing that happens with greater air flow is that the air cools - which is how it is probably possible to get the gains on the butt dyno.

So the air itself isn't much of a difference in temp with the stock box to a CAI box, but when you add a higher flow that decreases the temp and allows your intake a higher o2 concentration.
So we all agree that they freakin work? ok......cool.
I've got it now :idea: i'll weld an air conditioner to my throttle body
Just turn your CAI into a beer cooler using dry ice... Kill two birds with one stone...

Sounds like another secret project to me! :rofl:
THAT i would like to see!

Actuallt me and a buddy took his windshield washer bottle and ran tubing from it into the car once. Our fluid of choice was whiskey.

Kids please dont try this at home.......it is not advised and should be performed by professionals. :evillaugh
Well, before I did my custom ram air mod on my Volant, my intake temp was on average 15-20 degrees warmer than ambient temperature. After the custom ram air mod (5" opening tube ramming air through front grille into cut hole in side of Volant), my intake temp now about 7 degrees warmer than ambient temperature.

I'm in humid south Texas too.

Dont forget to install a fast opening, direct acting kanooter valve.:bouncy:

Oh and after you install that remove it and reinstall OEM parts to justify your hypothesis.:rollingsm

I think I need some photos of that. Anyone ever done a ram intake from the hood?

I'll get some this weekend.

Done the same thing. OBDII readings for AIT (air intake temp) is no more than 5 degrees over ambient temp.

I've tested my Hybrid Volant VS my friend's SE with stock intake.
Same identical vehicle: SE, CC. '04. Even the color is the same. I have the "Scan Gauge" and we hooked it up into the OBD-II ports. We ran our trucks one at a time, same route, same speed, same distance and the passenger wrote the temps at specific locations of the route.

Result: My volant maintained 5-7 degrees above ambient temp and his truck was reading 40-50 degrees higher than me.

Nice!!! Thanks for adding your findings as well. BTW, thats a sweet looking intake mod with the carbon fiber look and all. Mine is installed strictly as directed, and I went out again last night just to see if it would retain the IAT as i was getting earlier that day. It still stayed appx. 8-10 degrees above ambient air temp. I got my data from my Scangauge II as well. It will be interesting this summer to see what the differences are.
