GrimmSpeed Radiator Hose Kit for Forester, WRX - Red

Your vehicle’s cooling system is only as strong as its weakest link, and often, that’s the old, dry-rotted OEM coolant hoses. Over time, these hoses lose their integrity, leading to cracks that can leave you stranded on the highway or racetrack. To ensure your car remains reliable—whether it’s a daily driver or a high-performance build—it’s essential to have radiator hoses that can withstand both everyday conditions and the increased temperatures and pressures of a built motor without bulging, leaking, or failing. This is where GrimmSpeed comes in.

GrimmSpeed is synonymous with top-tier parts manufacturing, creating components that can endure whatever you put them through. The new GrimmSpeed Silicone Radiator Hoses are no exception. Made with a 5-ply construction system featuring fiber reinforcement between each layer, these hoses maintain their shape and durability throughout the life of the vehicle. Designed by reverse engineering factory hoses, they offer a perfect fit and easy installation—no trimming or kinking required. Available in black or red with the iconic GrimmSpeed logo embedded, these kits come with an upper and lower hose, as well as four stainless steel high-torque clamps from BREEZE. Every kit is tailored to fit various Subaru models. Backed by a Lifetime Warranty, these hoses will be the last set you’ll need to purchase.
