Im gonna have to disagree on that one. My SMA ColdAir intake is putting me on some nice times, and better throttle response. I have no problems with it either. Its hard to say if it really does suck in hot air from the tranny...being air is sucked in while your driving so how warm can it actually get flowing from the filter to the engine, in a matter of less then a second. The KKM sucks in air that has already been trapped in the engine bay.
