The full rundownProduct details
Heat, pressure, time—factory hoses eventually fail. These don’t.
The Fuji Racing Silicone Radiator Hose Kit replaces your OEM top and bottom hoses with high-temp, high-pressure silicone lines that are built to last. Designed to handle extreme engine bay temps and long-term abuse, these hoses deliver both performance and reliability in one clean upgrade.
Every hose is handmade using custom jigs, ensuring a precise, repeatable fit. The internal lining is OAT coolant compatible and rated from -150°C to +230°C—ideal for tuned builds, track use, or just peace of mind on the daily drive.
