MODIFYING THE STOCK AIRBOX
It seems that the reason CAIs such as the AFE flows so much more air than the stock box is because it has much more surface area that is actually exposed to the air. What if you just cut out the bottom of the stock airbox, and eliminate that small restrictive hole in the side that air is sucked through, allowing more air into the stock tube that leads to the throttle body such as the AFE. Then replace the filter with a drop in K&N. The filter would still stay in place because it is held up by flat surfaces half way up the box. I know many people who I talked to who have done this on the old model F-150s etc (my previous car, well truck) and it seemed to work great! Is that at all a good idea for the mustangs?

RE: INTERESTING
does anyone know how much more air is acceptable without a tune?
rygenstormlocke: what does lean refer to on these cars? Im almost sure its the air/fuel ratio but I want to make sure
The stock tubing only allows a certain amount of air in and isn't it when you increase the diameter of this tubing with a better filter that results in the car running lean?

I have seen CAI kits that require retune that do not include maf tube.
