And as for the heated intake from the fentons you should have both hooked up if you want anything to happen. With one you are essentially trying to push hot air into a sealed chamber with a single line. Without the second line connected you are not allowing the hot air to move around and circulate. I went with water heated on mine. During a cold start i just have to let mine idle a few more min to get the intake warm unlike the old stock instant heat setup.
