Not sure either, but it was just a midnight idea I had when I was working on the car one night - figured it would either help or do nothing
The IAT savings come from the hood, in my opinion and analysis. I was taking note of some temperatures yesterday, nothing officially recorded, but off the top of my head:
On a drive to Denver (85 miles for me) and back, with very heavy throttle use for the sake of experimenting, even at WOT it only got to 10 over ambient, then dropped to 1-2° over ambient within 30 seconds afterwards. This was on a 90° day too, so definitely not a cool day. I’m very curious to see how much the hood effects the IATs, so over this upcoming weekend, I may put the stock hood on and try and scientifically repeat a test and look at the results.

Another aspect of what I had worried about and why I put the additional shielding - back before I had a catch can, I had a breather cap which would spew quite a bit of oil... idk if it’s hot enough or even possible, but I’d rather not have my air filter burning, melting, or catching fire.
