Description
The Mishimoto Silicone Radiator Hose Kit, part number MMHOSE-WRX-15BL, replaces the factory rubber cooling hoses on your Subaru with a blue, four-layer silicone upper hose, lower hose, and coolant overflow port hose. Built for drivers who push their Subaru hard on track days or rallycross events, this kit is engineered to resist the degradation that plagues stock rubber hoses over time.
Where stock rubber hoses harden, crack, and weep coolant as they age, Mishimoto’s silicone construction uses heat-resistant embedded fibers across four layers to deliver improved heat and pressure tolerance, rated to a maximum temperature of 330°F. As part of Mishimoto’s broader line of cooling components, this hose kit is designed as a direct, specific fit rather than a universal solution, so installation stays straightforward. Each kit ships with four worm-gear clamps to secure the hoses in place, making the swap easy for a home garage install, and every Mishimoto hose kit is backed by the Mishimoto Lifetime Warranty for long-term peace of mind.
