Yes, IAT = Intake Air Temp. Heat soak is a bitch in this car, especially without a proper oil cooler. There are a number of things you can do to help combat it, but there is no true solution except for driving fast to get some airflow.

The stock intake box and silicone post-MAF tubes are a lot better at insulating intake air from the engine bay heat compared to metal tubes on most aftermarket intakes. The are some DIY mods for older model years with the "fangs" in the front bumper to help get more airflow to the intakes, but ambient temperature only does so much against the heat of the VQ.

A proper oil cooler helps with engine bay temps. As can upgraded radiator and/or fans. A tune can adjust the fans to come on sooner (lower temp) to help stave off heat soak as much as possible.

But the end result is if you drive the car hard its going to get hot. And if you stop while its hot, it is going to heat soak. And high IATs are going to pull timing.
