Description

The Mishimoto MMHOSE-WRX-01MBK is a matte black silicone radiator hose kit engineered specifically for the Subaru WRX and STI platform. Built with a dual-layer construction that combines high-grade silicone with heat-resistant embedded fibers, this hose kit is designed to handle serious underhood heat while delivering a direct, OEM replacement fit.

Mishimoto Cooling products are built to keep engine bay temperatures in check, and this silicone hose kit is no exception. The dual-layer silicone and fiber construction is designed to efficiently reduce heat and increase pressure tolerance compared to standard rubber hoses, all while maintaining the fitment and routing of the original equipment hoses. With a maximum temperature rating of 330°F, this kit is built to stand up to demanding conditions under the hood, giving WRX and STI owners a durable, performance-grade cooling component that installs in place of the stock hoses.
