Greetings. I live in the southwest where it's most often 90-100+ degrees outside with full sun. (I've heard this makes the pavement 140!) I wonder if a cold air intake will have the same or any effect in this weather. Then it floods like crazy in the monsoon, so an intake at the bottom of the car can easily suck in water.
BTW I've noticed my G35 has more oomph at 70 degree night versus 99 degree day.
