Should we be replacing anything to avoid potential fire hazards?

The only issue that I am aware of Boxster fires is from a failing power steering hose leaking power steering fluid onto the headers/exhaust which ignites causing a fire.

This mostly occurs to cars that are tracked when the potential for highly elevated power steering temps are more likely.

For a street car, inspect the power steering hoses regularly and you should be fine. For tracked street cars, the UDP is throught to help mitigate this issue by reducing the load, and therefore temps, of the power steering system. Dedicated race cars have the option to install a separate power steering fluid cooler along with the UDP.
