Z1 Motorsports Silicone PCV Hose for the Driver side of the VQ35DE found in all '03-'06 350Z & G35 models. 

4 ply reinforced high quality silicone hose, custom formed for perfect fitment.  This hose is located on the driver side of the engine, connecting the driver side valve cover to the upper plenum.

Over time the factory rubber hoses will crack and deteriorate creating vacuum leaks that will rob you of power and make the car undrivable.  The factory PCV hoses are also prone to oil build up from dirt and oil collecting in the hoses.

This is the last PCV hose you will ever need.  Unlike conventional stock rubber hoses that deteriorate over time, dry rot, and ultimately crack this silicone hose will stay soft and never degrade.  Best of all it costs less than a new OEM rubber hose. 

Please note: If you are using a "Z" Tube on your G35 you should choose 350Z from the model options below as the rear PCV hose is shaped differently for the Z. 

Z1 Motorsports offers a full line of silicone hoses for the 350Z & G35 that will be the last hoses you will ever have to purchase.  They will outlast the car at a comparable cost to new OEM replacements!  There's no reason to consider anything else.
