The Mishimoto MMHOSE-WRX-01BK Silicone Radiator Hose Kit is a direct-fit cooling-system upgrade for compatible 2002–2007 Subaru WRX and 2004–2007 Subaru WRX STI applications. This black 2-piece hose kit replaces the factory upper and lower radiator hoses with high-grade silicone hoses designed for improved heat and pressure tolerance.
Mishimoto constructs these hoses with a dual-layer design that combines high-grade silicone with heat-resistant embedded fibers. The kit retains OEM-style fitment while providing a durable replacement for aging factory rubber radiator hoses.

Installation
Mishimoto lists an estimated installation time of approximately 45 minutes. Always allow the engine and cooling system to cool completely before service. Drain the coolant, replace the factory upper and lower radiator hoses, secure the new hoses with the supplied clamps, refill the cooling system with the appropriate coolant, and bleed the system according to the vehicle service procedure.
Mishimoto notes that proper upper-hose orientation is important and that minor trimming may be necessary on some applications due to engine-bay packaging.
