🔧 Product Description

Genuine intake silencer used in the supercharger air system of Volvo Penta D11 marine diesel engines.

🚤 Compatibility

Typically suits:

  • Volvo Penta D11A-C MP
  • Volvo Penta D11A-D MP
  • Volvo Penta D11A-C (IPS)
  • Engine Family: D

⚙️ Key Features

  • Genuine Volvo Penta inlet silencer
  • Reduces supercharger intake noise
  • Maintains unrestricted air supply
  • Correct D11 mounting and connection profile
  • Used with air outlet 21162922 and supercharger 21145185

🔌 Function

The silencer reduces intake pulsation and supercharger noise while supplying the engine with a stable airflow path.

⚠️ Common Signs of Failure

  • Increased intake noise
  • Cracked housing
  • Restricted airflow
  • Loose connections
  • Dust entry
  • Reduced engine power or black smoke
  • Rattling from internal damage

🛠️ Service Notes

  • Sits between air outlet 21162922 and supercharger 21145185 - inspect both while the silencer is off
  • Check for anything shed inside the silencer before reusing it; debris here is drawn straight into the supercharger
  • Confirm the mounting and joints seal fully, since a loose silencer both increases noise and lets unfiltered air past
