Mishimoto Silicone Radiator Hose Kit Nissan 370Z 3.7 V6 2009-2020 – Black, Red or Blue

Replace ageing factory rubber coolant hoses and upgrade the engine bay of your Nissan 370Z with the Mishimoto Silicone Radiator Hose Kit.

Developed specifically for the Nissan 370Z, these hoses provide an OEM-style replacement fit while offering the durability and temperature resistance associated with high-quality silicone construction.

The kit uses a dual-layer construction incorporating high-grade silicone and heat-resistant embedded fibres. This construction helps the hoses tolerate the demanding temperatures and pressures experienced within the cooling system, making them an excellent upgrade for both standard and modified 370Zs.

Whether your Nissan is used as a daily-driven road car, fast-road build, show car or performance project, replacing older rubber radiator hoses with Mishimoto silicone hoses provides a practical cooling-system upgrade while also improving the appearance of the engine bay.

Direct Fit for Nissan 370Z

The Mishimoto kit has been designed as a direct-fit replacement for the factory radiator hoses on 2009-2020 Nissan 370Z models.

UK-market 370Z models use the naturally aspirated 3.7-litre V6 engine, including standard 370Z V6, GT and NISMO variants.

High-Grade Silicone Construction

Unlike conventional rubber hoses that can deteriorate with repeated heat cycles and age, Mishimoto radiator hoses are manufactured from high-grade silicone reinforced with heat-resistant fibres.

This design provides improved resistance to:

• High coolant temperatures
• Cooling-system pressure
• Repeated heating and cooling cycles
• Age-related hose deterioration
• Performance driving conditions

Maximum Temperature Rating

The Mishimoto silicone radiator hose kit is designed to withstand temperatures of up to approximately 330°F / 166°C, providing a significant operating margin for demanding cooling-system environments.

OEM Replacement Fit

No custom fabrication should be required when replacing the corresponding factory radiator hoses. The hoses are formed specifically for the 370Z cooling system to provide an OEM-style replacement fit.

Available in Three Colours

Choose the colour that best suits your 370Z engine bay:

Black – MMHOSE-370Z-09BK
Ideal for a subtle, factory-style appearance.

Red – MMHOSE-370Z-09RD
A bold performance-inspired upgrade that stands out in the engine bay.

Blue – MMHOSE-370Z-09BL
Classic Mishimoto styling for a distinctive modified engine bay.

Why Upgrade Your Nissan 370Z Radiator Hoses?

The cooling system is critical to maintaining stable engine temperatures. Factory rubber hoses are exposed to continuous heat, pressure and coolant throughout their service life and can eventually become hard, swollen, cracked or weakened.

A silicone radiator hose upgrade is particularly worthwhile on older 370Zs, performance-modified vehicles and cars that regularly experience demanding driving conditions.

The Mishimoto hose kit combines an upgraded construction with direct-fit installation, making it an excellent preventative-maintenance and engine-bay upgrade for the Z34 Nissan 370Z.

Important Fitment Note

Vehicle specifications can vary according to model year and market. Please compare your existing hose layout before ordering if your vehicle has an unusual cooling-system configuration or aftermarket cooling components installed.
