The turbocharger forces more air into the engine to increase power and efficiency, typically rated at 425–460 horsepower depending on the engine calibration. It is replaced when the original turbo fails due to worn bearings, excessive oil leakage, or loss of boost pressure, restoring engine performance to factory specifications.
