Product Description
This silicone hose kit replaces the failure-prone PCV hoses on all 2003-2006 Nissan 350Z and Infiniti G35 models equipped with a VQ35DE powertrain. Over time the factory rubber hoses will crack and deteriorate creating vacuum leaks that will rob you of power and make the car undriveable. 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. These are the last hoses you will ever need. Unlike conventional stock rubber hoses that deteriorate over time, dry rot, and ultimately crack, silicone hoses will stay soft and never degrade.
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.
The Z1 Silicone PCV Kit includes the following hoses:
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
Z1 offers a full line of custom-formed silicone hoses for your Nissan and Infiniti! CLICK HERE to shop the complete line of Z1 Silicone products.

These hoses are great quality. Installed on a 2005 350z. Valve cover is plastic and second hose is installed on to plastic male ends. I broke one trying to get old hose off. Had to replace valve cover. Learn from my mistake be careful when taking driver's side off and if needed remove the 10mm bolts holding the bracket on to allow more space to remove hose.

These look great in blue and my original spring hose clamps fit. The hoses are an exact fit, exactly like the stock hoses in shape and everything. The stock front most hose of the 3 actually has no hose clamps from the factory. I verified this from the factory exploded diagrams. I like mine!

These are great for replacing those crusty old hoses that, by now, have all but deteriorated. Every time I come across a vacuum or PCV hose on my 18 year old vehicle, and have a need to move it, it would nearly fall apart in my hand. Won't have that worry again with these!!! Great fit using OEM hose clamps.

Amazing product, very high quality, and a good upgrade. Also was fast shipping. 4 stars because most of the OEM clamps do not fit back on due to the hoses being thicker, witch is a good thing but maybe offer a option with these products for a new clamp that fits well.

Super high quality, as all the z1 hoses are. These are a must if you are doing anything from valve covers down, as the valve cover vent hose that connects the two is gonna be so hard, it'll crack. Very easy to install, and adds a great look to your engine bay. You wont find better hoses, and the price is unbeatable!
