depends on how you port it

Depends on how you port it and other mods. With the right porting a 30 hp + gain is possible and alot more with extreme porting like bridgeing.

If you are talking about the intake manifold then not very much from conventional methods such as gasket matching. Maybe a couple but nothing you will feel. You have to do something really radical to it before you really feel it or see any big differences. Theres not much you can do to that piece (T-II) that will do much unless you decide to start cutting things open like the plenum and getting crazy with a die grinder in there. Then you will end up changing the usable powerband. It can be improved a good amount but unfortunately it will take a standalone ecu to reap the benfits from any serious mods and your powerband may or may not change to your liking. Unless you are using a standalone ecu, and have done everything else possible to the car, don't worry about it. If you get to this point you should be pondering an entirely different and better intake manifold anyways.
