Z1 has not changed their hoses, I just got off the phone with Spencer @ Z1, it's the same shrink wrap (black netting plastic protective) that they sell as an option with their kits. I bought this option ($30) when I ordered my kit. The truth is, he said to get some heater hose or water hose or low pressue fuel line hose and insulate it where ever it touches any body parts. He said they probably should add some to the kits for future sales. Dunno if it will happen thou. One note he made that was interesting is that it's not widespread and specific to no certain model or year but some cars are more noisey than others meaning it's just how they are mfg'd. So some may get the whine noise and some may not, but it's safe insurance to spend the extra $10 on the above mentioned insulatation hose and wrap it (sleeve it) when there is any contact with other parts of the car or the body of the car. I will be heading out this Sat for some hoses prior to my installation.
