It is not just the temperature, but the filter location of the G3s also will net a much larger ram air effect once the car is at speed as they are placed directly behind the biggest opening on the entire front of the car. The Injens are still partially linked to the hot engine bay even thought they are way at the bottom while the G3's filter locations are completely separate.

There is probably not an appreciable difference in intakes temps between the G3 and Injen intakes, but the ram air effect of the G3's filter location will still give it the edge in my mind.
