in order for a cowl induction to have an advantage the air needs to go directly to the air intake, not the whole engine compartment. take for instance this Chevelle which had a stock cowl induction, see the thick rubber gasket around the intake? when the hood is down this sticks up into the cowl and seals the air intake from the rest of the engine compartment, making sure that no more air is going in there than necessary

its not about cowl induction.... its nothing about any type of induction at all. its simply about moving air through the engine bay as youre moving. allowing the engine to get a cooler source of air to help cool things off.
think of this... pop your hood up on a mid summers day after driving on the highway for and hour or so. when you open the hood, its hot. everything is hot, the engine, exhaust, intake manifold, battery, hoses, wires, air. now..... open the back of the engine bay up, by raising the hood a couple of centimeters... after a mid summers day driving on the highway for an hour or so. pop open the hood. it will still be hot. the exhaust manifold, engine, etc will still be hot, but not as much because there was some sort of air flow over everything.
dont think this is my personal view on it. ive heard of people doing this for several years. does it help? i dont know.... does it hurt anything?... i dont know...
