You can see (hopefully) from that equation that lowering the temperature will increase the density with no change in pressure.

Excuse me, I should have said, "IN THIS CASE, air density and pressure are in direct correlation to each other, since air temperature variance is not a factor being that air density rises at a rate of .0017 PSI per 10 degree temperature change at 14 PSI.
So, anyways, whatcha think? Is ram-air via cold air scoop on a car hood possible?
Since you consider .0017 PSI to be significant enough to argue about, I take it your answer would be...yes?
