Is this only for Na FC? I search on the web but most of the NA owener didn't put it in........... I just wondering is it a gas saver only?
Cause it seem like if we put it in the FC NA, the hood have to change to T2 hood too.
Thanks for your help.

 

You definitly won't save gas over a properly running stock fuel injection system. Anyone who says that this is a fuel saver is either crazy or nieve.

 

Theoretically it can get you more power due to a better intake setup, but I think you can get at least as much with a standalone, and definately a more usable powerband.

 

So, is it will increase for more HPS? I don't know is it good for NA and the people who like to do the swap. I means, at least the NA car can get some more hourse power.

 

I don't recommend running a carb unless its a track-only car. It screws up drivability and reduces gas milage, plus I don't think its that much of a hp gain, at least over a properly tuned car with a fuel controller of some sort.
