If I wanted outside, non-air conditioned air, I turned off the AC, turned the recirculating to outside, and the fan blew fresh outside air.
When the systems were off, no air came out from the vents.

1) no air leaks in when fan is off
2) air "leaks in when fan is off, but temp is relatively equal to outside air
3) air leaks in when fan is off, temp is hotter than outside air

My counterpoint/counterargument to the posted "problem":
- S13 240SX: blows air inside with fans off and recirculation off
- P10 G20: same
- P11 G20: same
- 2005 Camry: same
- 1992 Infiniti Q45: same
The air "leaking in" is a combination of the location of the intake of the A/C system, as well as any leaks in the cabin whether it's windows or something else. I've never found this to be a problem for my BRZ, and frankly it's welcomed as makes the car more fuel efficient, all else equal.
