Big Improvement Over Stock. Mishimoto’s Silicone Radiator Hose Kit withstands heat better than your Mustang’s stock hoses. These dual-layered radiator hoses reduce heat and have improved pressure tolerance. This means the chance of your hoses leaking or bursting is greatly reduced for the entire life of your car. Durable Construction. These silicone radiator hoses have two layers, one silicone and one constructed with embedded heat-resistant fibers. Together, these layers hold up to temperatures as high as 330 degrees. The blue color of the silicone adds a little style under the hood of your Mustang. Easy to Install. You can install this set of 6 radiator hoses with common hand tools. They are designed to be a direct-fit replacement for your car’s OEM hoses.
