Product Description

The **Mishimoto MMHOSE-WRX-01BK Black Silicone Radiator Hose Kit** is a premium cooling upgrade designed to replace the aging or degraded stock rubber radiator hoses on GD-chassis Subaru WRX and WRX STI models built between **2001-2007**. Constructed from high-grade reinforced silicone with heat-resistant embedded fibers, these hoses offer improved pressure and temperature tolerance compared to standard rubber hoses, helping maintain consistent coolant flow and reduce heat soak in boosted or spirited driving conditions.

This kit includes two silicone radiator hoses with four heavy-duty worm-gear clamps for a secure, leak-free installation. The black silicone finish not only provides long-lasting performance but also enhances the overall look of your engine bay. Designed as a direct OEM replacement, the MMHOSE-WRX-01BK installs easily without modification - providing a reliable upgrade for both stock and lightly modified turbocharged WRX and STI applications. Backed by Mishimoto's Lifetime Warranty, this hose kit delivers improved durability and cooling reliability over the original rubber components.
