BorgWarner Remanufactured Low-Pressure Turbocharger for International MaxxForce 9 9.3L
Replace a worn or failed low-pressure turbocharger with this genuine BorgWarner remanufactured B2FS turbocharger for select 2010–2012 International MaxxForce 9 9.3L engines. Part number 12749900077 is designed for qualifying I354 applications equipped with the factory two-stage compound turbocharger system.
The EPA10 MaxxForce 9 uses separate high- and low-pressure turbochargers working together to provide responsive boost throughout the engine’s operating range. This B2FS unit is the low-pressure stage of that system. It is not the complete compound turbocharger assembly and does not include the high-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 tag number from the original turbocharger or the International/Navistar original equipment 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.
