I installed my CAI first and plan on getting my hi-flow cat H-pipe in January. Anyway, the cold air definitely made a noticeable difference. MAC claims about 10-12 hp and I have no reason to doubt it. The H-pipe should yield around 15 hp. I can't wait to get my pipe! I am hungry for a more aggressive sound. Also v8powered, the 3.73s really do make a sweet difference, especially down low. Good luck!
