^if ur gonna attach it to the oem airbox then no if not then yes u should bolt to something so it doesnt move around

 

Thanks a ton man. I have it attached to the the OEM airbox with a drop in filter.

 

Good setup. I think the addition of the Z-Tube with <whatever intake> has a more noticable effect when you have a non-oem exhaust. It just lets the car breathe better all around and with a larger exhaust and possibly hfc's you will notice it much more.
