I never said airflow wasn't necessary. I said it was "minimal".
I still think spending time and money on roof scoops to get air in is a waste of time. Because the air coming though the scoops is going to be directed right out the top of the engine lid Scoops look cool (to some people anyway), other than that, they are useless.
I'll say it again... The greatest place to increase airflow into the engine bay will be from underneath the car and up through the engine lid vents. And I dont think you can increase anymore air into the engine bay until the size of the engline lid vents are increased. That's where money is better spent.
