Why use silicone instead of rubber hoses/radiator hoses? Silicone has a much higher temperature yield. Another benefit of good silicone under high temperature is its increased adhesion properties to metal under high temperature. Also, radiator hoses are cooled from the direct transfer of coolant/water which allow the hoses to have a longer life.
Normal rubber hoses stiffen over time and this causes them to split under pressure. Silicone will have a much longer life.
That being said I bought a set of the OBX brand silicone hoses for my GT, honestly hate the "wrapped" look of them and will be putting a hose cover of some sort on them before I install them.
