This component serves as a critical intake tract upgrade for 2011-2016 Chevrolet and GMC trucks equipped with the 6.6L LML Duramax diesel engine. The stock component, often constructed from restrictive materials, can impede airflow into the engine’s cylinders. An aftermarket replacement typically features improved internal volume and smoother flow paths, often fabricated from materials like mandrel-bent aluminum or stainless steel. The improved design is intended to provide a more direct and less turbulent route for air entering the engine, supporting enhanced combustion efficiency.
The implementation of an enhanced intake system offers several potential benefits for the engine’s overall performance. Improved airflow can translate into increased horsepower and torque output, particularly at higher engine speeds. This upgrade can also contribute to reduced exhaust gas temperatures (EGTs), leading to improved engine reliability and longevity. Furthermore, by optimizing the air intake process, fuel economy may also be positively impacted. Early designs were often focused solely on increasing diameter; modern designs consider the velocity and laminar flow of intake air through modeling and testing.
