This LML Y-Bridge Kit is an upgraded high flow intake kit for the 2011-2016 6.6L Duramax diesel engine which replaces the OEM upper intake manifold supplying air to the engine intake runners and cylinder heads.

Key Features

  • This kit improves air flow by 36% using a precision CNC machined cast aluminum high flow bridge which provides maximum airflow volume for the available space.

  • Incorporates factory intake air heater grid for superior cold weather performance.
  • Billet resonator plate eliminates the stock plastic resonator for improved engine bay appearance and more aggressive turbo and engine sound.
  • Finished in your choice of custom powder colors.
