Product Description

The Torque Solution TS-SU-420BK Silicone Radiator Hose Kit is a direct-replacement cooling upgrade designed for a wide range of Subaru performance models. OEM rubber radiator hoses can dry out, crack, and weaken over time due to heat cycling and age - especially in turbocharged applications. This silicone kit replaces those aging parts with high-strength, multi-layer silicone hoses that resist heat and pressure far better than stock, helping maintain optimal coolant flow and reliability.

Finished in a sleek black and fitted with stainless steel clamps designed to protect the silicone from damage, this kit not only enhances durability but also improves the appearance of the engine bay. Installation is straightforward thanks to the direct-fit design, and the hoses are engineered by reverse-engineering new OEM units to ensure an exact fit. Backed by Torque Solution's limited lifetime warranty, this kit is ideal for daily drivers and performance builds alike who want long-lasting cooling system components.
