Product Description

Z1 Silicone Oil Filter Coolant Hose Kit for all '03-'06 350Z & G35 models equipped with the VQ35DE Engine.

The VQ35DE engine is equipped with a special sandwich adapter that cools the engine's vital oil as it is passed from the block to the oil filter.  By allowing the cooler engine coolant to circulate around the oil passages, the engine's coolant can thereby extract any unnecessary (...and harmful) heat from the oil.  This will not only result in cooler oil temperatures but will greatly extend the life of the engine. Over time the factory rubber hoses will crack and deteriorate forming coolant leaks.  Not only will this allow air into the coolant system, but this will prevent the cooling system from functioning at its full capacity.

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.

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.

This kit includes all 3 necessary hoses feeding coolant to the oil filter sandwich adapter, located on the passenger side of the engine.

I had a pretty bad coolant leak from a torn hose that connects to the top of the oil cooler. These hoses were a direct fit and solved my overheating problem! I’ve been driving my Z occasionally for the last few weeks and no issues so far!

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

My short formed hose was in pretty bad shape, I found it to be leaking where the OEM spring clamp was, I added a SS clamp until I got new hoses ordered. The new hoses are super quality compared to OEM rubber hoses, they were formed correctly and now I don't smell coolant after I get home after the vigorous stop and go traffic that Atlanta has to offer. Wish I would have purchased these hoses three years ago!
