-- [ From: Bob Nogueira * EMC.Ver #3.1a ] --
Far be it for me to disagree with Lawrence and Owens but I can't help but
think the louvers do remove some hot air. I base this on my experience with
leaking fluids. Any time I have had a coolant or oil leak I end up with more
fluid on the windscreen than anywhere else. It flys out the louvers back to
the screen.
Also in summer, I can't use the Areo screens since the heat coming
out of the louvers will singe your eyebrows off.
