ISR Performance Silicone Radiator Hose Kit - Scion FR-S / Subaru BRZ - BLUE

The ISR Performance Silicone Radiator Hose Kit for the FR-S and BRZ in blue is a silicone replacement for the factory rubber radiator hoses. Higher heat range, higher pressure tolerance, and silicone's anti-expansion property prevents the hose ballooning you eventually get from aging rubber. Cleans up the FR-S/BRZ engine bay while it cleans up the cooling system.

What It Does

Factory rubber radiator hoses soften and expand under coolant pressure as they age. Silicone hoses are stronger than rubber and resist that expansion entirely, holding their shape through the full range of operating temperatures and pressures. On the FR-S/BRZ platform. which sees a lot of track and autocross use. this is the kind of cooling system upgrade that pays off in reliability and visual cleanup at the same time.
