For 2007+ Nissan 350Z VQ35HR owners, this reinforced silicone coolant hose kit replaces aging rubber hoses to support reliable coolant and vacuum routing during repairs or upgrades.

2007+ Nissan 350Z VQ35HR Silicone Coolant Hose Kit

The SPELAB Motorsports Silicone Master Hose Kit is designed for 2007 and newer Nissan 350Z models equipped with the VQ35HR engine. Each hose is custom formed to follow the factory routing and connection points, helping provide accurate fitment and straightforward installation.

Factory rubber hoses are constantly exposed to engine heat, coolant, pressure, and repeated temperature changes. Over time, they may harden, swell, crack, or develop leaks. Replacing worn hoses with reinforced silicone components can help improve the reliability of the cooling system while refreshing the engine bay.

• VQ35HR 3.5L V6 engine models

Note: Please verify your vehicle year, engine code, hose routing, and connection sizes before ordering.

Why Upgrade to Silicone Hoses?

Silicone hoses are designed to remain flexible under repeated heating and cooling cycles. Compared with aging factory rubber hoses, reinforced silicone hoses offer improved resistance to heat, pressure, cracking, and long-term deterioration. They are a practical upgrade when servicing the cooling system, rebuilding the engine, or replacing worn original hoses.

Installation

The hoses are custom formed for application-specific fitment and are intended to replace the corresponding factory rubber hoses. Professional installation is recommended. Always allow the engine to cool completely before opening the cooling system, and inspect all clamps and connections during installation. Refill and bleed the cooling system according to the vehicle manufacturer’s procedure.
