The best is the stock air box. The idea of a CAI (cold air intake) is providing cooler air for the intake. The stock set-up does this by drawing the air from the wheel well. A lof of the aftermarket kits that replace the complete air box unit only has a plate to help block heat from the engine but, it still draws a lot of the heat.
