The BorgWarner 11637100000 EFR 7163 Iron-Bearing Cartridge is a top-tier replacement core (CHRA) designed for high-performance turbo assemblies. Built with a rugged iron bearing housing, it delivers exceptional durability under elevated boost pressures.

It allows full flexibility in selecting compressor and turbine housings, making it perfect for bespoke setups. Note that compressor and turbine housings are not included and must be sourced separately - the cartridge is designed as a core rebuild or upgrade component.
