Application & Compatibility
Source application path clues for buyer verification. These are source category/application paths, not confirmed fitment claims:
- CUMMINS
This HE221W turbocharger is listed for Cummins engine applications. It is associated with OEM reference numbers 4047746 and 4956071, which serve as verification clues for your specific powertrain.
- Application Clue: Cummins

Technical Notes
The HE221W model is a fixed-geometry turbocharger. This configuration uses a static turbine nozzle ring, meaning vane count and height are fixed at the factory and cannot be adjusted during operation. Buyers should verify these physical dimensions against their existing Cummins unit to ensure the correct replacement application.
- Turbine Design: Fixed-geometry nozzle ring
- Verification Step: Cross-check nozzle ring vane count and height against OEM reference 4047746 or 4956071
- CHRA Balancing: Ensure the core assembly is balanced to specification before installation
- Housing Check: Confirm turbine housing flange type and bolt pattern match your engine setup
