"the stock intake is great" is, IMO, one of the biggest wive's tales on here. With a VF on my 07, switching to an AEM CAI gave noticeable gains. Car spooled more readily, making more torque everywhere. The tuner stated that the later model intakes are even more restrictive, meaning there are more gains to be had.

Tuner also was emphatic that intakes must be tuned for, so either get protuned, or use a map specifically made for the particular intake you choose.

And don't cry about how you should only run a CAI if you live in a desert for fear of hydrolocking, if you don't drive through foot-deep puddles you will be fine. Course it never rains where I live, in Seattle.
