MAHLE Turbocharger P/N:479TC20177000

Restore forced-induction boost with the MAHLE Turbocharger 479TC20177000, a direct-fit replacement for the 2003-2005 SAAB 9-3. A turbocharger uses energy from the engine's exhaust flow to spin a turbine wheel, which drives a connected compressor wheel that pressurizes intake air — packing more air into the cylinders than a naturally aspirated engine can draw on its own.

• Forced induction: Exhaust-driven turbine and compressor deliver the pressurized intake charge the engine relies on for its designed boost.
• Direct-fit application: Built as a replacement turbocharger for the listed SAAB 9-3 applications.
• MAHLE build: Supplied by MAHLE under manufacturer part number 479TC20177000.

Signs the original turbocharger may need replacing include a loss of boost pressure, a whining or whistling noise under load, blue exhaust smoke, or a boost-related check engine light. Because these symptoms can have other causes, diagnose the source before replacing — if a failed turbocharger is confirmed, this unit replaces it. Consult the vehicle service information for the correct fasteners, oil-supply lines, and gaskets, and whether any may be reused.
