Will an aftermarket air filter be necessary, or can you just bolt the stock airbox back in?

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???

This is not entirely accurate, as the intake will offer gains with the stock air box and exhaust. The combination of the intake, CAI and free-flowing exhaust will produce more power than the intake with a stock exhaust and air box, but the intake will still off the same percentage gains with both combinations.
