my 2014 ford fusion 2.0.. there have been some problems with the turbo and cat. damaging the electornic steering and it cost a LOT to replace it,,, the car has heat sheilds in the area.. but just stamped steel....i am thinking to clean really, really good, and apply the gold tape to the ( facing ) the heat source.. and perhaps add a extra heat sheild to prevent any heat getting to any $$$$ parts
