The 2.3L already has a ton of things in the mix, but the previous V6's haven't had too much(k&n and ???) except for the 2.5L Duratec. Since the 3.5L will be used in a few Ford vehicles, that might change. But as for the revised 3L that most people will get other then the 2.3L, will probably not see a whole lot. Look at the options for the 3.5L in Nissans for example, cams, stroker kits, exhaust, intakes, blowers, turbos, etc... Basically what I'm asking is who with a 3L would be interested in some of those performance options, and then maybe someone will see that there is an interest.
