building a cowl induction hood

Umm, wont that just let hot engine bay air into your cowl area where it will get sucked into the interior when you have the fan blower on?

It may but the air moving around the car will most likely push the engine air over the car instead of into the cowl.

I don't use the heater that much anyways. And I also figure that now the hot air has somewhere to go instead of over heating inside the engine compartment.
