Description
The Mishimoto Silicone Radiator Hose Kit (MMHOSE-WRX-15BK) replaces your Subaru’s degradation-prone rubber cooling hoses with a black, four-layer silicone construction reinforced with heat-resistant embedded fibers. This specific-fit kit bundles the upper radiator hose, lower radiator hose, and coolant overflow port hose along with four worm-gear clamps so the whole cooling upgrade installs as a matched set.
Rubber is out, silicone is in. Where factory rubber hoses can crack and degrade over time, this Mishimoto silicone hose kit is built as a Performance-grade cooling component designed to hold up to a 330°F maximum temperature rating while improving heat and pressure tolerance under sustained load. Whether your WRX or Forester 2.0XT is out on track day laps or tackling a local rallycross event, this kit is engineered to keep coolant flowing reliably through the system, and it’s backed by the signature Mishimoto Lifetime Warranty.
