ISR Performance Silicone Radiator Hose Kit – Scion FR-S / Subaru BRZ
ISR Performance has released a line of Silicone-based coolant hoses that are designed to take a higher range of heat and coolant pressures than the OEM style hoses. Silicone has a much higher strength than the OEM rubber hoses which will prevent the hoses from expanding.
With aggressive driving, your coolant pressure will rise above the rated OEM pressure. Replace it with silicone hoses that can take the high pressure and not deteriorate like the OEM ones!
