Each Z1 Silicone Radiator Overflow hose is made of 2 layer reinforced silicone.

This hose will dress up your engine bay and is easy to install. 

Hoses come long enough for NA applications, but can easily be trimmed on the straight end to shorten the hose for use on a tt radiator.  

Each hose is formed with a hook end for factory original like fitment.   

Available in high gloss Black, Red, and Blue.
