During development of various 2016+ Q50/Q60 components our engineers noted that the factory rubber coolant hoses are a potential area of failure as your Q50 begins to age. So, we set out to develop a replacement hose kit using durable silicone that*s guaranteed to outlast and outperform your stock hoses. Mishimoto silicone hoses are constructed from five layers of silicone with embedded heat resistant fibers. The silicone construction improves heat tolerance, and the internal fiber layer provides higher pressure tolerance. In addition, silicone offers improved physical properties compared to EPDM rubber, making it more resilient to degradation over time. Our silicone radiator hose kit includes a full set of stainless-steel worm gear clamps for ease of installation. We offer this kit in black, blue, or red. As with all our products, this kit includes or signature Mishimoto Lifetime Warranty. Silicone Radiator Hose Kit, fits Infiniti Q50/Q60 3.0T 2016+
