The trade off is that at lower speeds in hot weather, hotter air will be injested that will lower your power until cooler air is brought back in with the car in motion. The best solution is some kind of free flow setup that draws cool air from right under the decklid intake.

hmmmm.....does having a Turbo wing have any effect on getting cool air into the engine compartment? I don't recall ever seeing a "cold air" system for older 911's like i see for many other cars
