Do not drive it. That is not the bent fin from ice that has been shown here on a few trucks. That is mangled from a hard object that was either dropped in intake post filter on assembly or maliciously from disgruntled employee at PDI dealer. .
If it were me I would demand a new truck because this is just purchased, and the turbo looks to have lost chunks of metal that have been blown into intercooler and possibly beyond.
If it were a bent fin like the ones that were affected by ice, I would say to keep driving it ( as some have done with no issues), have turbo replaced and carry on, but this is completely different. But, bolt ,screw, something was left in the intake and you should not have to own this truck.
