Product Description

Z1 Motorsports Silicone Brake Booster Hose Kit for all '07-'08 350Z 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 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, which is now discontinued and no longer available new!

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 or a check valve added inline (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.

Available in:

  • BLACK
  • BLUE
  • RED

Absolutely nothing wrong with the quality of the product, but many more attention to safety should be revised. I ordered them and they sat for a while because i was waiting for my supercharger which took 6 months to arrive. I forgot there was a check valve in the OEM hose because its been 6 months since ordering. I believe there should be an Edit to the part Description, instead of the note being in blue it should be in red because this is in fact a very critical safety hazard after going boosted. As well as a safety label in the box about the check valve, or many include one with the new hoses so this doesn't turn into a possible accident for someone.
