A recent underbody inspection of my car revealed that the right hand side (US passenger side) intercooler piping was rubbing against a sharp bolt/rivet on top of the steering gear shaft. It's hard to see in the below photo, but the piping is almost worn all the way through. It has not penetrated the kevlar layer yet so as of now, no boost leak.
For now, I have placed several layers of black duct tape over the area but It will eventually wear through. I recommend everyone inspect their hoses for similar wear. There is a relatively easy fix that is more permanent. A small piece of tin sandwiched between a protective layer and taped or glued over the vulnerable areas would provide sufficient protection. Another idea I have is to 3D print a small plastic brace that would lift up and support the piping just enough to clear the steering shaft. My drawing below isn't good but gives you an idea of what I'm talking about. Unfortunately, I have no way to create this brace but some of you might. I did not observe any degradations on the left hand side piping. I have about 5,800 miles on the EC intercooler at this point.
