yup, heat rises. Plus, even at highway speeds, they wouldn't get as much airflow as they would with a fmic. Yes, they have hood scoops, but they are still fighting against rising heat in the bay. Nothing beats direct flow from the front. The only way to get better results with a TMIC or SMIC is chemical cooling like water/methanol injection
