And obviously I will clean the car hahahahaha.
By the way I have never seen someone taking fresh cool air from there.And I quite like the sleeper standard look of my Rx-7 , so change the bumper for the new or the gt-c to get more air is not an option.
The only mod that I made at the outside is that I open 2 holes in the hood ( well I have one hood for spare) it dosn't look nice at all , but it is 100% necessary, one cause the T° inside the hood is so bad that make all the electronics of the rx7's last less , and the wiring too , and 2 cause when you drive at hi speed you have + pressure inside the hood that make your hood looks like its going to fly away.
By theory in that place is where is less pressure when you drive so I should be the best place to make a hood vent , that suck the hot air from the engine and turbo
I will appreciate if you can show me some little real small CF hood vent so I can change this ones, by the way it was the smallest ones that I found

I did the same thing but I used 2 seperate 3 inch rubber flex hoses and for the "air scoop" I used 2 shop vac attachments. I installed the two shop vac attachments behind the passenger brake duct and routed the hoses up to directly under the air filter(about 2 inches from the bottom of the filter).
The picture with the white dotted line shows how I have the second shop vac attachment mounted. You can see the vertically mounted one clear as day. I simply used the bumper to be my "air box" to guide the air into the hoses.
Cheap but effective and my AIT temps are very low when above 30mph. At 70mph I see the temps drop dramatically.

nice color!!!!
Yep the problem is all ways at low speed , cause at hi speed the air pressure is so hi that it get into the engine bay by everyware. last week I just ended tunning up an S2000 with individual runners , and open air filter , at hi speed ,when the outside T° was 20°c in the intake was 10° , but at low speed it get to 30°C. So I made an cool air intake from one of the fakes entrances of air in the bump , now it get to 20°max and at hi speed is quite the same , meaby 9°C.

This is not up for argument. This is a FACT.
So, either your IAT is wrong
or you are bullshitting.

But I know that that's happens cause there is a difference in the pressure that make that the air takes some heat from the surround in special in the case of the individual runners that I got in the S2000. and drop the temperature.
For Ex ,In the case of the Sport Kartings (Im talking of the 125cc 2 strokes) , just check out the temperature of the intake before the carburetor after a race , and let me know if it less or the same that the ambient air temperature.
It the same that the way that the refrigerator works , when you expand the gas it takes temperature from the surrounding (-P) and in the opposite like the turbos , when you compress it , generates heat.
If you want I can give you the physics formulas with the reason why that's happens , but I agree you with you in some way , cause my first impression was the same that the AIT sensor was wrong or the EMS ECU was bad or bad calibrated.

Ok, I'm not a real physic but I know why that's happens, In fact when I have that readings , the first impression was that the IAT sensor was wrong.

I bet the induction noise of those ITB's sounds Glorious at WOT

"Elusive, not deceptive!”
I think most of the temp drop that you were feeling at the carb can be attributed to the heat of vaporization of the gas, not just the lowering of the pressure.
