I have a ripped hose that connects to my intake that i think is causing my weird idle, i’ve tried looking it up and can’t find it anywhere, does anyone know what the hose is and where it connects? Also, is it a vacuum hose i could just get from an auto parts store ? thank you

 

Check google for G intake tube, it’s likely the vacuum hose on the bottom of the intake hose there.

 

There are 3 hoses that make up the PCV system on the VQ35DE, that's the hose that runs from the intake tube to the left side valve cover.

You have the Stillen intake which I believe uses the 350Z PCV tube, not the G35 one.

 

PCV valve, hose and o ring or gasket G35 from (2003 to 2008)

Part number for the PCV valve

O ring/gasket sold separately

Part number for the PCV valve hose

Old PCV valve, gasket/o ring, and hose after taken out. When install new parts get 2 hose clamps for each end of the hose. 10 minutes job. Enjoy more life to you baby!
