Varis Cooling Bonnet - does it really cool?

This is exactly why most hood scoops for combustion air toward the front of the hood don't any good and can actually reduce performance. A good hood scoop is either tall enough to get into higher-pressure air (which causes a lot of drag and hinders vision) or located near the base of the windshield (and facing rearward). Front vents work better for pulling hot air out of the engine compartment.

A picture (or two) is worth a thousand words.
