BorgWarner Cartridge EFR 9174 (Iron Bearing Housing)

This is the core assembly of a BorgWarner EFR 9174 turbocharger, featuring a cast iron bearing housing. It comprises the rotating assembly (compressor and turbine wheels) and the bearing system. This part is a cost-effective solution for rebuilding EFR turbochargers when only the internal components or wheels are damaged, provided the existing compressor and turbine housings are in good condition. The EFR series is recognized for its advanced features and performance, including a forged milled compressor wheel, an integrated compressor recirculation valve, an integrated boost control solenoid valve, dual ceramic ball bearings, a water-cooled cartridge, and a gamma titanium aluminide turbine wheel, contributing to its light weight and high heat resistance.
