The BorgWarner EFR 9174 cartridge with an aluminum bearing housing provides the internal rotating assembly for compatible EFR turbo housings. Intended for turbo rebuilds or upgrades, the cartridge lets you refresh bearing and rotor components without replacing the external housings, facilitating maintenance and performance restoration in EFR‑configured turbo systems.
