Product Features

The 20931029 air cleaner outlet duct assembly is built to match factory performance and installation requirements:

  • Directs filtered air from air cleaner housing to intake system
  • Designed specifically for 4.3L V6 engine configuration
  • Maintains sealed airflow path to prevent unfiltered air entry
  • Matches factory routing for proper fit and clearance
  • Supports consistent airflow under varying engine load
  • Built to GM specifications for correct installation

Application Notes

The 20931029 is intended for trucks equipped with the factory intake system listed above, and it needs to be properly seated to avoid air leaks. A loose or misaligned duct can affect airflow readings and engine performance.

Always verify part number, engine configuration, and intake routing before installation.
