The Mishimoto silicone radiator hose kit for 2001–2007 Subaru WRX and WRX STI replaces factory radiator hoses with dual-layer, high-grade silicone reinforced by heat-resistant embedded fibers. It’s an OEM-fit replacement intended to improve heat resistance and pressure tolerance, rated to 330°F, and designed to reduce heat soak compared with stock hoses while fitting factory connections on supported Subaru models.
