3 Important reasons why Silicone hoses is better than Rubber hoses:
Silicone’s resistance to Heat
esp for high temp applications such as radiator hose areas that don’t have much air flow so the silicone with stay supple for longer and resist cracking and bulging, splitting esp as the hoses age, black hoses are fine for a short time but with break down very fast causing problems. Esp in hard to reach places and in places where a lot of work has to be done to get to the hose that needs to be replaced. $7 in silicone may save you big $$$ in the long run.
Flexible
Long last but also easier to install because you can fold and push it in STORY
Longer Lasting
High heat loads will last long (elaborate).
