BorgWarner Remanufactured High-Pressure Turbocharger for International MaxxForce 9 9.3L Replace a worn or failed high-pressure turbocharger with this genuine BorgWarner remanufactured B1UG turbocharger for select 2010–2012 International MaxxForce 9 9.3L engines. Part number 11559900049 is designed for qualifying I354 applications equipped with the factory two-stage compound turbocharger system. The MaxxForce 9 uses separate high- and low-pressure turbochargers working together to provide responsive boost across a broad operating range. This B1UG unit is the high-pressure stage of that system. It is not the complete compound turbocharger assembly and does not include the low-pressure turbocharger. The 9.3L I354 engine evolved from International’s DT570 platform, so this turbocharger may also appear in parts catalogs under DT570 or MaxxForce DT570 terminology. Fitment should always be confirmed using the original turbocharger or International/Navistar part number. This turbocharger is remanufactured by BorgWarner to restore critical dimensions, clearances, and operating performance. The completed assembly is inspected and tested to support dependable service in demanding International medium- and heavy-duty applications.
