  Description:

  Genuine OEM Nissan Active Radiator Grille Shutter Assembly — Part # 21421-4MT0A

  Restore proper aerodynamic efficiency and cooling system management to your 2024–2025 Nissan Rogue with the factory-correct active grille shutter assembly. This genuine OEM assembly contains the electrically actuated shutter vanes that open and close behind the front grille — reducing aerodynamic drag and improving fuel economy when the engine doesn't need maximum airflow, and opening fully when cooling demand increases. Direct factory fit for the Japan-built Rogue.

  Part Details:

  • Part Number: 21421-4MT0A
  • Other Names: Shutter Assembly-Radiator, Active Grille Shutter, Radiator Shutter Assembly, AGS Assembly
  • Condition: New, Genuine OEM Nissan
  • Position: Front — behind radiator grille (Reference #20 on diagram)
  • Application: 2024–2025 Japan-built Rogue

  ⚠️ Critical Build Origin Note — Japan Built Only: This shutter assembly fits Japan-built 2024–2025 Rogue models only. US-built Rogues use a different active grille shutter configuration. Japan-built Rogue VINs begin with JN8. Always confirm your build origin with your VIN before ordering — this is one of the most common ordering errors for this part.

  Compatible Vehicles:

  • 2024–2025 Nissan Rogue (Japan built — JN8 VIN prefix)

  Always confirm fitment using your VIN before purchasing.

  Why buy OEM? The active grille shutter system requires precise actuator calibration and vane geometry to integrate correctly with the Rogue's ECM cooling management strategy. Aftermarket shutter assemblies are virtually nonexistent for this application, and any substitute risks incorrect vane response, motor incompatibility, or AGS fault codes. The genuine Nissan assembly is the only unit built and validated to the T33 Rogue's aerodynamic and cooling specifications.

  Symptoms this part fixes:

  • Active grille shutter warning light or fault code
  • AGS actuator not responding — vanes stuck open or closed
  • Reduced fuel economy — shutter not closing in low-demand conditions
  • Engine running warmer than normal — shutter not opening under cooling demand
  • Shutter assembly physically damaged from a front-end impact or road debris
