GrimmSpeed Radiator Hose Kit (08-21 STI, 08-14 WRX)

Your vehicle's cooling system is only as good as its weakest link, commonly that’s the old, dry-rotted OEM coolant hoses. As your vehicle ages and the integrity of those hoses degrades, cracks develop and you can suddenly find yourself stranded on the side of the highway or the racetrack.

To keep a car reliable, whether it’s a daily driver or a high-horsepower build, it's important to make sure your 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, leaking, or altogether blowing up. That’s where GrimmSpeed comes in.
