Note: that is a threaded IAT sensor. You'll have to weld in a bung on the intake. There is a press in sensor, but I dont know the part number. Wasnt sure it would hold under boost anyway.
I just looked up the IAT sensor for a base 98 corvette on rockauto. It is not threaded. I haven't had any problems with 12 psi. A threaded one isn't a bad idea though.
I think the treaded one is from a typhoon? I have the push in one and its holding fine @ 11 psi but the treaded/ metal one would probably be the ideal set-up.
The push-in will stay in just fine and you will most likely never notice it leaking boost unless you actually make tools for doing a boost leakdown test. I have pvc end caps with schrader style air fittings threaded in them that I clamp to the charge piping to pressurize the entire system and check for leaks before ever driving the vehicle. It will save you a lot of hassle to fix the leaks before going out and tuning it. I had one Z06 that would never hit the boost it was suppose to when it came in the shop and I tested it and found all 8 lower injector o-rings leaking badly at only 3psi.
Here is the threaded IAT to use. #25036751
It's a 3/8-18 NPT thread.

Use the purple and tan wires:

I know this is a old post but I'm relocating my IAT sensor on my 2001 coupe with the screw in IAT Sensor (25036751) and the pigtail. What I'm having trouble with is trying to figure out what wire go were. Inside The Sensor it has a small slot and a larger slot, what wire goes to small slot side? Is it the purple one or the tan one? And what wire goes to the other side?
Thanks
Ok, Sorry for reviving an old thread but I figured it would be easier to post in here rather then start a new threa. Ok, the vehicle is a 2002 ZO6 and I have purchased a screw in IAT sensor and weather pack to delete the intigrated MAF/IAT combination relocate the IAT sensor on the back on my LS2 Intake manifold. As far as I know it dont matter which of the two wires go where in relationship to the blades on the sensor but my question is which two wires do I use? I read here that it's the tan and purple wires. However, I read on another forum that it's the brown & black/white wires? Can anyone help me with this?
Thanks for the infor gents! I already have my sensor that I'm going to run.

IF that diagram is correct, it's purple and tan. For sure it's 2 on the end. The way an IAT works, it doesn't matter which way you wire the purple and tan to the pigtail, just do purple to one and tan to the other.

Right, I understand that it dont matter which wire (because its a resistor). I was wondering is it the purple and tan wires or the black/white and brown wites as it suggested on another corvette forum.
