Interesting point the 2 guys make about the positive pressure in the engine
compartment trying to lift the engine cover while driving at speed. That
is engine compartment pressure vs interior pressure. I wonder what the
pressure difference is engine compartment vs side air plenums. Visually it
looks like air would ram into those intakes on the upper sides and cause
high pressure and airflow in the plenums but maybe it really doesn't not.
Somebody put an air flow meter in there and see what it shows at various
speeds. Right side with plate intact and left side in its stock open
configuration. Thank you!
