Going to replace my water pump on my LBZ and I'm going to go ahead and change hoses while I am draining the system. Is there any performance improvement on silicone hoses? Or other hoses for that matter? I do a lot of heavy pulling with my truck and would like to see cooler temperatures if there is an option. If they aren't worth the money I'll stick to OEM as I don't really care about looks in the engine bay that much. Thanks in advance.
