Yes, once the car is moving temps come down. The temp difference is pretty dramatic in stop and go traffic or normal commuting. Once you get to freeway speeds, you're right, the temps come down. But if you log IATs on this platform, the short rams are sucking in a lot of hot air at lower speeds and you can feel it pulling timing.
EDIT - That's why the OEM setup with drop in filters and silicone maf tubes works so well. It's still drawing outside air. You just leave a few HP on the table vs long tubes.
