People install them for the look, the arguable HP gains, and on some rare occasions, actual better throttle response.

"optimal"-I think a better word would be compromise. Performance and air temperature are probably on the bottom of the priority list (most cars). On my '01 Accord you could barely hear the engine running from all those dang resonators. In the case of the G35 engine noise (reducing) took the lead and it's obvious based on the "z-tube".
The setup on the G35 can draw cold air. If you follow the air path coming in the grill, it comes up through the hood latch and there sits the air filter ducts. The hood seals to the top of those ducts so the air has to come in from the front.
From all I have read cold air intakes tend to be restrictive at higher RPM due to their length.
Best bang for the buck is z-tube and drop in k&n, every little bit helps.
