Description
The Mishimoto MMHOSE-Z-23BK is a direct-fit silicone radiator hose kit engineered specifically for the 2023+ Nissan Z, replacing the factory rubber coolant hoses that Mishimoto’s engineers identified as a wear point as these cars age. Finished in black, this kit was developed to outlast and outperform the stock hoses on the Z’s VR30DDTT-powered RZ34 chassis.
Built from five layers of silicone with embedded heat-resistant fibers, this Mishimoto cooling hose kit is designed to improve heat tolerance while the internal fiber layer boosts pressure tolerance. Compared to factory EPDM rubber, the silicone construction offers improved physical properties and greater resistance to degradation over time, making this a performance-grade upgrade for anyone looking to protect their Z’s cooling system for the long haul. The kit also arrives with stainless-steel worm gear clamps so installation is straightforward from the start.
Vehicle Applications
This hose kit is a specific fit for the Nissan Z, covering the Nismo trim for 2024–2025, the Performance and Sport trims for 2023–2025, the Proto Spec trim for 2023, and the Touring trim for 2023–2024. It is designed around the Z’s 3.0L V6 with engine code VR30DDTT on the RZ34 chassis.
