Turbocharger Cartridge for Mazda CX-7

Restore turbo performance on your Mazda CX-7 with the Rotomaster New Turbocharger Cartridge, part number K1040216N. This direct OE replacement is built for 2007-2011 Mazda CX-7 applications and focuses on the core wear components inside the turbo assembly.

Rotomaster’s New Turbocharger Cartridge line is built for repair work where the compressor and turbine housings can be reused. That approach can reduce teardown time while keeping the repair centered on the damaged cartridge rather than replacing the entire turbocharger.

Key Features

• Direct OE replacement for 2007-2011 Mazda CX-7 turbocharger service
• Journal bearing design for standard-duty applications
• Oil and coolant cooling method
• Allows reuse of the original compressor and turbine housings

Product Details

The Rotomaster K1040216N turbocharger cartridge is a new, standard-grade replacement built around the internal core of the turbocharger. When the housings remain serviceable, replacing the cartridge can address bearing and rotating assembly wear while preserving the original turbocharger shell components. This makes it a practical repair path for Mazda CX-7 turbocharger service, especially when diagnosing a cartridge-level failure rather than a complete housing failure. The K1040216N is assembled with OE-grade components to support consistent operation in oil- and coolant-cooled turbo systems.

This part cross-references N104216C for the same application.

Common Problems It Can Help Solve

• Turbocharger shaft play caused by worn internal bearings
• Loss of boost from cartridge wear inside the turbo core
• Oil leakage related to internal turbocharger wear
• Coolant and oil-cooled turbo service where the core assembly has failed
• Need to repair a Mazda CX-7 turbocharger without replacing reusable housings

Installation Notes and Tips

Before installation, inspect the compressor and turbine housings for cracks, scoring, or heat damage. Confirm that the oil supply and return passages are clean, and verify that the cooling system is free of contamination. Because this cartridge is supplied as a direct OE replacement, it is important to follow the vehicle service procedure for turbocharger removal, inspection, and reassembly on 2007-2011 Mazda CX-7 models.

Rotomaster builds this new turbocharger cartridge with OE-grade components for durability and consistent performance. The cartridge format is intended to support a focused repair of the turbo core while retaining serviceable original housings on Mazda CX-7 applications.
