I did my PHH in silicone and I kinda regret it after seeing all the trouble people had with that type of hose, but I kinda think that one is short enough and most of it is connected to steel pipes(I kept mine because it was fine and I had a lot of other fish to fry when it came to doing my head job) that it probably couldn't weep too much coolant out of the 1/2" or so that is actually exposed.Thanks for the feedback on the filter. I got all excited and ordered the entire HPC silicone heater hose kit and read here that they are prone to fail so quickly canceled my order. Off to the dealer to order them individually. Learning from others mistakes....I don't need anymore setbacks.
That said, I wish I would have just went with the Gates Green Stripe for everything.
