Product Details

This Rotomaster New Turbocharger Cartridge is engineered for applications where the damage is isolated to the turbo core rather than the full assembly. By replacing the cartridge instead of the complete turbocharger, technicians can retain the original housings and complete the repair more efficiently. Part number K1040215N is a standard-grade, journal-bearing cartridge with oil and coolant cooling, built to support reliable turbocharger operation on 2006-2007 Mazda 6, 2007-2013 Mazda 3, and 2012 Mazda CX-7 applications. This part cross-references Monroe Shocks & Struts (e.g., N104215C) for the same application.

Common Repair Symptoms
