can some post a picture of what a z-tube looks like? the reason why i'm asking is because i was looking at my stock intake yesterday and the tube coming out of the airbox has a big Z on it. just wondering if this is the regular g35 part, or if i have a z-tube. also, what exactly does it do? thanx

 

Just log onto Performance Nissan to look this up, I believe they have a picture posted.

 

z tube is the one on top. why? supposed less air restriction = sound change and improved performance. how much is arguable.
