True...The stock intakes pull 100% of their air from in front of the radiator. The R2C's are not sealed to the pass through so some engine compartment air is gonna get in...Same as my set-up. IAT's can go as high as 150 degrees when sitting and heat soaking. Ventilating the airbox (either stock or R2C) will bring those temps down fast as soon as the car starts moving.
I didn't do a lot of IAT monitoring when I had my stock box on, but I have since doing my custom intake. I have it up in real time on my Scangauge. No ventilation, temps will run 15-20 degrees above ambient. Ventilate and those drop to 5-10 degrees. The cooler the IAT's the more the timing advance and consequently the more power you have on tap..
