What is normal intake air temps on the highway?

What do you all see as normal IAT temps while cruising on the highway as well as during a hard pull. Please share the ambient temp at the time as well.

My IATs are pretty consistent at 20-25 degrees over ambient temps ranging from 50-90f. The only time it really rises is when i'm at idle.

I think that depends on your driving mode . This cooling system is really conservative in cooling down the air so if you are cruising on the highway in comfort mode, the active grille may never need to open and that will bring your IAT to the high 50 or 60C.

But if you are in sport Plus and are doing WOT runs the cooling system will start to bring it down to ~42C , in a 20C ambient.

Do you have a turbo heat shield installed?

My IATs are pretty consistent at 25-30 degrees over ambient temps ranging from 45-100f.
