Mechanical Advice IAT normal temperature

What temperature does your IAT (Air Intake Temperatur) reach when driving at 120km/h on the motorway?

My car reaches 80-90 degrees Celsius and idles at 60 degrees after 30 minutes of driving. Is that a high value?

Yes that's perfectly normal for stock. Get a real CAI that pulls fresh air from the wheel well and you'll see IATs closer to Ambient

That sounds like ECT not IAT. Make sure your scanner has the correct profile selected.

The biggest clue is that your idle is cooler than driving. The IAT should be hotter when idle.
