Description
The Mishimoto MMHOSE-WRX-01BL is a blue silicone radiator hose kit engineered specifically for the Subaru WRX and STI platform, replacing the factory rubber hoses with a dual-layer silicone construction reinforced by heat-resistant embedded fibers. Designed as a direct, OEM-style replacement, this Performance-grade kit is built to handle sustained heat while maintaining a factory-correct fit in the engine bay.
Standard rubber radiator hoses can degrade over time from constant heat cycling and coolant pressure, eventually leading to swelling, cracking, or leaks. Mishimoto’s silicone hose construction combines high-grade silicone with embedded fiber reinforcement to efficiently manage heat and increase pressure tolerance, giving the cooling system a more durable connection between the radiator and engine. As part of Mishimoto’s broader Cooling lineup, this hose kit is intended for enthusiasts who want a longer-lasting, performance-oriented alternative to the factory hoses without altering the vehicle’s OEM hose routing.
Vehicle Applications
This specific-fit hose kit is designed for the Subaru Impreza WRX from 2002 through 2007, including the WRX Limited and WRX TR trims covering 2006–2007. It also fits the Subaru Impreza WRX STI from 2004 through 2007 and the WRX STI Limited for the 2007 model year. Additionally, this kit is compatible with the Saab 9-2X Aero for the 2005–2006 model years, reflecting the shared platform between Subaru and Saab during that period.
