Z1 Motorsports Silicone Brake Booster Hose Kit for all '03-'06 350Z & G35 coupe models.

4 ply reinforced high quality silicone hose, custom formed for perfect fitments. These hoses connect the brake booster to the upper intake manifold supplying the necessary vacuum.

Over time the factory rubber hoses will crack and deteriorate creating vacuum leaks that will rob you of power and make the car undriveable.  Any leaks or lack of vacuum for the 350Z or G35's braking system will result in an undesirably firm brake pedal and could possibly pose a safety hazard.

These are the last Brake Booster hoses 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.

This kit comes complete with the following hoses:

Z1 Silicone Brake Booster Hose (Booster Side)  Z1 Silicone Brake Booster Hose (Booster Side)
Z1 Silicone Brake Booster Hose (Engine Side)  Z1 Silicone Brake Booster Hose (Engine Side)

Please Note: The one way check valve needs to be removed from the factory hose and reinstalled in the Z1 silicone hose (This is essential for engines equipped with forced induction)

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.
