Rubber is out, silicone is in! Upgrade your old Chevrolet Impala radiator hose with the Mishimoto 1966-1968 Chevrolet Impala Silicone Upper Radiator Hose to provide your Impala with an advancement in both style and reliability. With this hose, two worm-gear clamps are included for ease of installation. Unlike the degradation-prone rubber hoses your Chevrolet Impala currently has, every Mishimoto silicone hose is constructed from five layers of silicone with heat-resistant embedded fibers to provide unmatched durability, heat tolerance, and pressure tolerance. Whether you take your classic to a show or use it to cruise on the weekends, trust Mishimoto with all your Impala parts. This silicone hose is available in black and, like all of our Classic Line parts, includes the Mishimoto Lifetime Warranty.
