Our Intake Manifold for your 2007.5-2018 Dodge 6.7L Cummins is built around a 3.5" inlet that smoothly transitions to two 3" mandrel bent tubes. This design also enabled the use of a short bolt in place of the long driver-side flange bolt that passes right through the center of the stock manifold air plenum. Thus freeing up airflow even more yet maintaining the stock six bolt pattern for a proper seal. The twin tube design nearly doubles the outlet size of the stock manifold while minimizing the impact of the initial section of the number one injector line.
