S&B 2004.5-2005 GM LLY Duramax Diesel Turbo Inlet Manifold 76-1006B

S&B part number 76-1006B is a performance turbocharger intake manifold upgrade kit for 2004-2005 Chevrolet and GMC trucks with the 6.6L LLY Duramax diesel engine.

The 2004.5-2005 GM LLY Duramax Diesel trucks have a known issue with their turbo inlet tube.  The factory part was a compromise in flow versus space.  With the addition of the EGR system, the inlet tube needed to take a sharp turn into the turbo.  This created a restriction to airflow in that turn.  To make things worse, some of the manifolds had an additional restriction due to the process of creating the part.  The plastic mold has a seam at the bend and extra plastic protrudes out into the airflow stream.  This is now considered the main reason for overheating issues during heavy towing conditions with LLY engine.  GM redesigned the turbo inlet tube on the next-generation LBZ engines and the overheating issues were a thing of the past.  This inlet manifold guides the airflow in the desired direction to a 78.6% increase in flow and reduces power-robbing turbulence.  This is a must-have for all performance and heavy work applications.
