Description
The Mishimoto MMHOSE-GC6-99BK is a purpose-built silicone radiator hose kit engineered specifically for the 1999-2001 Subaru Impreza RS. Finished in black, this kit replaces both the upper and lower factory rubber radiator hoses with silicone construction rated to a maximum temperature of 330°F, giving your Impreza RS’s cooling system a genuine upgrade in durability over the degradation-prone rubber it left the factory with.
Every Mishimoto silicone hose in this kit is built from five layers of silicone reinforced with heat-resistant embedded fibers, a Cooling-focused construction method designed to improve heat and pressure tolerance compared to aging rubber hoses. Whether your Impreza RS sees local rallycross events, regular track days, or daily street duty, this Mishimoto hose kit is designed to hold up where stock rubber hoses eventually crack, soften, or fail. As a Specific-fit, Performance-grade cooling component, it’s a direct, no-guesswork upgrade rather than a universal hose you have to trim and adapt.
