The BorgWarner EFR B2 9280 cartridge with an aluminum bearing housing is a replacement rotating assembly for EFR B2 turbos, configured to the 9280 specification. It allows rebuilding or upgrading a turbocharger by replacing the internal cartridge rather than the housings, restoring rotor and bearing function for EFR‑series applications that accept the 9280 core.
