The stock air boxes are effectively cold air intakes from the factory. There is a short plastic tube that directs the air to the air box filter compartment, collecting air from behind the front fascia.
There are only a few minor tweaks that can be done to make it better, such as cutting holes in the fascia (Mine's nose holes) or extending the tubing to collect from another fascia opening (fang vents etc). The second tweak it is to replace the corrugated intake tube sections with something smoother, such as silicon. And finally you can replace the stock air filters with something that lets a little more air (and dirt) in.
