Yup..What you are seeing is very close to the results I got. My intakes are not sealed to the Fang vent tubes, but IAT's cool down much faster from underhood soak and generally run 6-10 degrees above ambient. If I were to seal the intakes to the inlets (or had stock air boxes) I suspect that number would be even lower.

With the vents, it's amazing to see how 150 degree+ temps dissipate so quickly after a red light heat soak...!

Not too many guys here have the abilty to measure IAT's so I don't suspect you'll get much response.

Cooler is better...

Some more data over here: Intake air temp data (Stillen Gen 3, need stock)

I haven't retested since installing my oil cooler, but I suspect the IAT's will have risen from the heat coming off the oil cooler right under the passenger-side Stillen Gen 3 filter. Pretty soon I'm going to order up some hose and flanges from Modshack's setup and see what I can make work for the Gen3. I'm actually considering the shop-vac ends (like he used for intakes for his brake cooling on pics of another car) at the top of the hose run to dump cold air over the Gen 3 filters.

Modshack, is there anyway to do your set up with the G3 Intake cause the intakes run right through the place where you put the hoses?
