infiniti fx35 performance parts

[infinitifx35]

I just got my fx35 a couple weeks ago and they haven't came out with any specific fx35 performance parts, but i was thinking about getting maybe g35 parts like a injen short ram intake. I don't know if thats a good idea or not. Ive seen my friends g35 and it looks identical under the hood. Anyone know for sure let me know thanks.

Cold Air intakes are a misnomer. Without direct access to outside air you can only suck in the air that's under the hood. That air is a long way from being cold. The reduction of resonators or air chambers may be of some benefit, but as far as cold air....Its not possible with the intake in the engine compartment.
A supercharger would make a 60 to 80 hp gain but they are not cheap, you are looking at about $6000.00 in the cost of the supercharger alone not including installation.
FXs come with a quasi dual exhaust system. not a true dual exhaust. You could modify that into a true dual exhaust system but there is the question of pressure balance and the computers ability to adjust to the modification, some exhaust modifications can hurt performance.
The least expensive way is to gain power is to remove restrictions from the air intake. You can be creative about that.
