For bigredtruck, sorry man, what I mean by the pressurized box is simply the big straw little straw effect. It reminds me of when I used to tinker with carburetors and the effects of trying to increase power by increasing more fuel and air to the engine. From a stock enclosed airbox on older cars/trucks, if you removed the lid and tried to run the engine around town, you noticed a significant loss in throttle response at bottom end but a drastic effect on mid to top end performance. Even with fuel injection now, and with IAT,TPS and MAF sensors on fully stock/OE vehicles, you are still losing bottom end performance from bolting on a CAI system without the addition of performance programs or other performance parts to bring it all together. Noticed this effect on every vehicle I bolted just a CAI on. Going back to the straw comparison; it takes more pressure to drink a milkshake through a tiny/skinny straw than it does through a big/giant straw yes? Thats what I was meaning by the OE pressurized box because it is sealed, dimentionally air limited and only has the small opening in the airbox to the wheel well air. Whereas a CAI, fully opened and dimentionally increased to air from inside or outside the engine bay. Sorry I got so technical but now I need a drink.
