having some more info on this would be amazing because im wondering the same thingSame exact mark on my heat shield.
I am concerned by a product like this though.
Wouldn't something like this lead to premature turbo failure as it essentially cooks the turbo in its own heat which should be allowed to dissipate?
I would think this would cause the oil/coolant of the car to also increase in temperature as the turbo heat has no other place to go.
Pure speculation of coarse. hopefully someone with an oil temp gauge can tell us what they find before and after this install.
