Who knows where i can buy the clear side markings/light thingy from? Also what performance upgrades are available for G35 coupe... Maybe for HP increase or Acceleration increase.

 

I just put the stillen high flow intake and the grounding kit on yesterday. The borla exhaust is on the way. Just from the intake I can tell there is a difference. Exactly how much I am not sure. It is advertised as around a 10Hp increase of so. The borla runs as high as about 12Hp increase. With that along with the grounding kit I expect somewhere in the neighborhood of 20-25Hp increase. But really the difference is in the throttle response so far with the intake. Cannot contest to the borla, but people tell me its an improvement - especially on the sound. Also, with the intake you can here the air being sucked in when you start from a stop, before the engine drowns it out. Hope this helps.

 

so the stillen intake is good? and the exhaust is good too?

Are there any disadvantes of these mods? and where did you buy them from

 

HEy WHAT about the Injen Cold Air Intake? Which is better and What are the costs?
