untill recently I thought any of the aftermarket cold air intake kits were the same, but I recently removed a volant intake and installed a k/n fipk intake on my truck. If I didn't witness the results myself, I would have never believed it, the k/n fipk made a drastic differance over the volant. It's a bit quieter and makes a very noticable differance in power. It also has a much cleaner and more sturdy install. I believe the two kits you were asking about are pretty much the same kit, I think the aircharger kit becomes the fipk kit once it passes the CARB approval certain states require. I believe they sell them under the aircharger name stating offroad use only, but once it passes they change it to a fipk kit.
