has any one thought of upgrading there hoses to either silicone or stainless? Im thinking of doing this in the next couple of months. My heater hose gave up on me and my car almost overheated. Luckily I was parking and my hot light came on. I immediatly turned the car of and let it coast into the parking spot. NaiSSo sells the silicone kit for 170 thinking about purchasing it. I feel it would be a smart investment.
