Lots of questions but that's because I'm interested in the product. 10whp is too good a gain to turn down if it is plug and play.

If the TB remains in the same position which it think it does you should be able to use the stock airbox.... BUT,, why would you do that? In order to achive the full benefits of an Intake manifold the car will require a performance Intake and Exhaust. Other wise what would be the point to invest on the Intake Mani???
