Please do add some more question marks. I'm not sure you used enough. The stock air inlet tube is not a restriction. The stock airbox lid and stock MAF/housing ARE restrictions. The Saleen upgraded airbox lid and MAF looks to be an excellent design. The resolution of the air transfer function may be suited for supercharged applications (same way as the 90mm Lightning MAF is to a naturally aspirated Mustang) or it may not. However, you incorrectly said, "Therefore there would be very little to be gained if anything at all if you were to replace the Mustang's stock airbox with Saleen's.." The Saleen unit uses a revised airbox lid and larger MAF housing.
On the 4.6 2V Panthers, going to a revised airbox lid with a larger MAF housing yields a 15-20 fwhp gain over the stock airbox. Raising the roof of the airbox lid increases the volume of that plenum which can effectively increase the amount of airflow going into the engine. On the other hand, the ribs on the stock air inlet tube are not restrictions regardless of how many question marks you use.
