Z1 Motorsports Silicone Brake Booster Hose for all '07-'08 350Z models. 

4 ply reinforced high quality silicone hose, custom formed for perfect fitments.  This hose is located on the passenger side of the engine compartment connecting the brake booster's vacuum feed line to the upper intake manifold.

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

This is the last Brake Booster 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, which is now discontinued and no longer available new!

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 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.
