Technical characteristics of the BMW turbocharger housing

• restore correct exhaust flow and rotor stability,
• reduce the risk of leaks and incorrect assembly thanks to the original geometry.

Product Condition and the Benefits of Choosing a Used OEM Part

The turbocharger housing is in used condition, meaning it has been disassembled but remains functional enough for continued use after proper preparation. For many users and workshops, this represents a reasonable compromise between cost and quality, especially for components with a stable, robust construction.

Choosing an original, used BMW OE housing ensures, among other things:

• factory fit to mounts and other turbocharger parts,
• material consistency with other components of the charging system,
• can be used in the process of professional regeneration carried out by a specialized service.
