Rubber is out, silicone is in! Upgrade your old Pontiac Firebird radiator hose with the Mishimoto 1967-1969 Pontiac Firebird Silicone Lower Radiator Hose to provide your Firebird with an advancement in both style and reliability. With this hose, two worm-gear clamps are included for ease of installation.

Whether you use your classic for daily driving or use it to cruise on the weekends, trust Mishimoto with all your Firebird parts. This silicone hose is available in black and, like all of our Classic Line parts, includes the Mishimoto Lifetime Warranty.
