This silicone hose replaces the failure-prone driver-side PCV hose on all 2003-2006 Nissan 350Z and Infiniti G35 models equipped with a VQ35DE powertrain. 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. Our silicone hoses are made from high-quality multi-ply reinforced silicone and custom formed for perfect fitment. Unlike conventional stock rubber hoses that deteriorate over time, dry rot, and ultimately crack, silicone hoses will stay soft and never degrade. These are the last hoses you will ever need!

Z1 silicone hose can be purchased in your choice of BLACK, RED, or BLUE.

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.

Benefits of Z1 Silicone:

• Exceptional thermal resistance prevents breakdown even at higher than normal operating temperatures.
• Superior flexibility when compared to rubber, making installation and service a breeze!
• Durable silicone material ensures these hoses will last as long as your truck.

Fits:

• 2003-2006 Nissan 350Z
• 2003-2007 Infiniti G35 Coupe
• 2003-2006 Infiniti G35 Sedan
