Silicone Radiator Hose Kits for Subaru WRX

The cooling system in your Subaru WRX is only as good as its weakest link.  More often than not, that weak link ends up being tired factory radiator hoses.  Their construction can lead to premature cracking, splitting, and bulging with age and continued heat cycles.

Reinforced silicone hoses have a higher temperature operating range, are more resistant to chemical reactions, and maintain their flexibility through a longer lifespan than factory rubber hoses. They happen to look much better, too.

Constructed of 3-ply reinforced silicone, these hoses will not only look better but also last longer. Silicone hoses have a higher operating temperature range, making them a must for any car that may see extended periods of aggressive driving or track time. COBB branding is found at both ends of the hose.

Included in each kit is one lower and one upper radiator hose, each with two clamps each.
