The GPP 3.5″ Intake Manifold for your 07.5-16 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. These design features amount to a 49.4% increase in flow over the factory manifold. With this vast improvement over the stock manifold you can expect quicker turbo spool, lower egt’s, and less over all strain on your motor. This manifold also includes instructions, a polished stainless dipstick mount, port plugs, a gasket and hardware to make installing this intake extremely easy.
