Turbo 01 1.8, 8 lbs of boost, 58k miles....
Temps have hit ~ 80* lately, my ultra-gauge shows IAT of approximately 40-50*F over ambient. 125* Saturday morning when it was ~ 75 outside.
That'll be 160* in a few months when it hits 100* outside.
Pardon the crappy wrap of the intake, I threw it on as I was leaving for work.. header wrap, poorly applied by me![facepalm](https://www.miataturbo.net/images/smilies/facepalm.gif)

If you have an intercooler and seeing those temps, youre doing something wrong.

Stock, newish Kia, just to use as a reference point.... If a NEW car has somewhat fluctuating IAT that run anywhere from ambient to 'whatever over ambient', then I can extrapolate some of that info to my NB. I also will start monitoring my wife's Kia Soul's intake temps too, just to see if they get so high over ambient.
Jank setup is still a work in progress, I didn't build it. Was told that it was experiencing higher than normal IAT's when I got it, I'm just gathering information.
It has the Bell Engineering intercooler #1 if I recall on it.

Post intercooler, about 2" behind radiator and fan, it blows fkin hot! I'm just trying to keep the heat OFF the aluminum. I GOTTA believe that air coming out of the radiator is heat soaking the aluminum connector pipe?
It's not an exhaust piece, how would YOU insulate from intense heat on that tube?

sorry bruh, try again.
You can reorganize this pretty cheaply. Really just look to move the location of the IAT closer to the intercooler and out of the way, or if you have access to someone who welds aluminum, you can have a bung welded to the intercooler end tank. Worst case, Begi sells a coupler with a bung attached you can use and just rework your cold side piping a tad. I don't know what's going on with the BPV, but it should be relatively ok to modify.
I'm personally switching some couplers around for my under tray to work and using the following sources:
2.5" coupler

BEGI reflash....
The IAT sensor is stock I assume, it's post intercooler, about 18"down from the throttle body, right in the line of intense heat coming from the fans. I didn't put it there, it was put there by the builder.
I wonder if it's a false sensor reading, or is it heatsoaked (also giving it a false reading), or if my temps really are that high in winter?
Katy, Texas to be exact. A/C runs every month of the year down here lol

This is still very much a work in progress
