unless i am mistaken it seems i may have heard of someone putting a cooing fan in the engine compartment to help blow some of the stagnant air out of there when the car is stopped or moving slowly. does anyone have these details?
I'd heard of people making the rear vents bigger though, I forgot who did it. I guess theoretically if you can make an engine compartment fan with some clever engineering. Enlarge those rear vents and put some fans behind them?
