I too recently got my g35 bone stock. I got my windows tinted and black out the rims and grill. Next will be a ztube,pop charger. Than maybe new clutch and other maintenance

 

Enjoy that pop charger and the loss of power it will create for you. Because it's not shielded all it will suck in is hot air from the engine bay which destroys the power the engine will create. Back in the day it was my first intake mod and after owning it for 4 weeks I sold that POS as fast as I could. Do some research on here about alternate intake choices and you'll thank me later.
