Grimmspeed Radiator Hose Kit [2008-2014 WRX, 2008-2021 STI]

A Subaru’s cooling system is only as good as its weakest link, commonly that’s the old, dry-rotted OEM coolant hoses. To keep a car reliable, whether it’s a daily driver or a high-horsepower build, it's important to make sure the radiator hoses are up for the job. They need to be able to handle not only everyday conditions, but also the increased temperatures and pressures of a built motor without bulging or leaking. That’s where GrimmSpeed comes in.

GrimmSpeed has always been synonymous with top-notch parts manufacturing and superior quality, developing parts that can handle whatever you throw at them. Things are no different when it comes to the brand new GrimmSpeed Silicone Radiator Hoses.

These hoses are manufactured using a 5-ply construction system with fiber reinforcement between each layer of silicone to ensure that they maintain their shape and durability for the life of the vehicle. GrimmSpeed Silicone Radiator Hose Kits were designed by reverse-engineering brand new factory hoses for a perfect fit and effortless installation. The kits are offered in a black or red color with the trademark GrimmSpeed logo embedded into each one and are available for a variety of Subaru applications. Every kit includes an upper hose, a lower hose and four stainless steel high-torque clamps from BREEZE.
