Description
Stock rubber hoses degrade under sustained heat and restrict coolant flow, compromising your Civic Si’s cooling efficiency and engine longevity. The Samco Sport silicone radiator hose kit replaces OEM hoses with handcrafted British engineering that withstands higher temperatures while improving thermal transfer—delivering up to 9°F cooler operating temps. Beyond performance, the factory-matched red silicone gives your engine bay a finished, professional appearance without sacrificing function.
