How would it "suck in" CO? there would have to be a CO leak to begin with
and that has nothing to do with the 8x8 hole that is probably just the
return for that particular area.

Depending on air circulation in the area, a danger exists of exhaust
gases being drawn into the air return. For that reason, a forced air
furnace installed in a closet often must have a combustion air supply
separate from the living space.

The purpose of outside combstion air is efficiency. You don't want to burn
the air you just heatgead and push it up the stack.

The colder outside air also has more air in the same space, right, and
more oxygen. Even if it is colder.
