[Healeys] Side Vents

The under-bonnet situation is that it is a high pressure area....meaning
that a lot of hot air stays in the engine compartment before it moves out.
The ralley vents allow an escape route for that air. That allows more air,
with less back pressure, to enter your radiator and move through the engine
compartment at a faster rate.  It will reduce the air temperature under the
bonnet. Not sure how much you will feel it in your feet but the vents look
cool and your engine will run cooler as well.

I put the vents in my race car 35 years ago to reduce engine temps and it
was very effective.
